Abstract
Psoriasis is a chronic, immune-mediated skin disease significantly impacting women, with disease severity often modulated by hormonal fluctuations. This review examines the influence of hormonal changes on the course of psoriasis in women, focusing on key life stages—including the menstrual cycle, pregnancy, postpartum, and menopause—and their impact on disease progression and symptomatology. Estrogen, the principal female sex hormone, plays a critical role in immune modulation. Variations in estrogen levels, which occur naturally throughout a woman's life, are associated with fluctuations in psoriasis severity. Low estrogen levels, as seen during menstruation or menopause, are linked to symptom exacerbation, while elevated levels during pregnancy may reduce symptoms in some women. However, responses are variable, with others experiencing no change or worsening during pregnancy. Postpartum, the rapid decline in estrogen often triggers severe flare-ups, while menopause, marked by a sustained estrogen reduction, frequently correlates with increased disease severity and flare frequency. The review also addresses the profound impact of psoriasis on women’s quality of life, including physical discomfort, psychological distress, and social stigma. Additionally, fertility concerns are discussed, as severe psoriasis and associated treatments may increase the risk of adverse pregnancy outcomes. Consideration is given to hormonal therapies, lifestyle modifications, and their effects on psoriasis, underscoring the need for personalized treatment approaches that account for hormonal influences. Understanding these hormonal dynamics is essential for developing targeted, effective management strategies that enhance quality of life for women affected by psoriasis.

Menstrual Cycle
-
Symptom Worsening During Luteal Phase and MenstruationIn the luteal phase (post-ovulation) and menstruation, estrogen and progesterone levels decline significantly, reducing their anti-inflammatory effects. This hormonal drop is linked to increased inflammation, often exacerbating psoriasis symptoms such as itching, redness, and scaling.[31] Research suggests that low estrogen levels may increase pro-inflammatory cytokine activity, such as TNF-α and IL-6, which are key players in psoriasis pathogenesis.[11,12]
-
Clinical ImplicationsRecognizing this cyclical pattern enables healthcare providers to implement proactive strategies, such as temporary increases in topical treatments or lifestyle adjustments, to mitigate flare-ups during high-risk phases of the menstrual cycle. Lifestyle modifications and stress management may also enhance symptom control and quality of life.[7,19,32]
Pregnancy
-
Improvement of SymptomsDuring pregnancy, many women with psoriasis experience symptom relief due to the anti-inflammatory effects of high estrogen and progesterone.[6,8,9] Estrogen has been shown to modulate immune responses by promoting an anti-inflammatory environment, decreasing levels of pro-inflammatory cytokines like TNF-α and IL-6, and fostering regulatory T cell activity.[11,12] Research indicates that up to 60% of pregnant women with psoriasis may see an improvement or even achieve remission.[32]
-
Variability in ResponseDespite the general trend of symptom improvement, a subset of women may experience no change or worsening symptoms. This variability could be due to genetic factors, environmental influences, and individual differences in immune system sensitivity.[32]
-
Immune System ShiftPregnancy involves a shift toward a Th2 immune response, which is less inflammatory and beneficial for psoriasis. This shift decreases Th1 and Th17 responses—typically dominant in psoriasis—and helps prevent excessive inflammation, contributing to symptom improvement.[33]
-
Clinical ManagementManaging psoriasis in pregnant women requires a careful balance between effective symptom control and fetal safety. Topical therapies are generally preferred, while systemic treatments are used cautiously due to potential risks. Collaboration between dermatologists and obstetricians is vital for optimal care, as psoriasis treatment must be tailored to minimize risks to the mother and baby.[9,31,32]
Postpartum Period
Rebound Effect and Symptom Flare-ups
-
Contributing FactorsIn addition to hormonal fluctuations, factors like sleep deprivation, physical recovery from childbirth, and postpartum stress can exacerbate psoriasis. Psychological aspects, including postpartum depression and anxiety, may also worsen disease severity, emphasizing the need for mental health support.[34]
-
Treatment ConsiderationsPostpartum psoriasis management should take a holistic approach, focusing on physical and emotional health, breastfeeding considerations, and social support. Topical therapies are generally preferred for their safety profile in breastfeeding mothers. If systemic treatments are required, healthcare providers must carefully weigh the benefits against potential risks for both mother and infant.[34]
Menopause
-
Increased Disease ActivityWith the loss of estrogen’s anti-inflammatory properties, many women experience more frequent or severe psoriasis flare-ups during menopause. Estrogen deficiency is linked to increased production of pro-inflammatory cytokines and decreased regulatory T cell function, creating an immune environment conducive to psoriasis exacerbation. Lesions may become more extensive or resistant to previously effective treatments.[7,8,10]
-
Skin Changes and SensitivityMenopause also induces changes in skin texture, such as dryness, thinning, and reduced elasticity. These alterations can worsen psoriasis symptoms by making the skin more susceptible to irritation, discomfort, and heightened sensitivity to treatments. Reduced skin barrier function in menopausal women with psoriasis may lead to an increased risk of injury or infection.[7]
-
Hormone Replacement Therapy (HRT)Hormone replacement therapy (HRT) may offer symptom relief by restoring estrogen levels, potentially mitigating psoriasis severity. Some studies indicate that HRT may alleviate menopausal symptoms and improve psoriasis outcomes. However, the effects of HRT on psoriasis vary among individuals, and HRT carries potential risks, including an increased risk of cardiovascular disease and breast cancer. A comprehensive evaluation of HRT’s benefits and risks is essential in managing menopausal women with psoriasis.[34]
-
Clinical RecommendationsIn postmenopausal women with psoriasis, healthcare providers should consider revising treatment strategies to account for hormonal changes and skin sensitivities. Adjustments may involve optimizing topical treatments, emphasizing skincare to address dryness and sensitivity, and evaluating the potential role of HRT in symptom management.[7,34,35]
4. Impact on Quality of Life
Physical Effects
-
Discomfort and PainWomen with psoriasis frequently experience persistent itching, pain, and skin tightness, which can worsen during hormonal fluctuations. Lesions in sensitive areas such as the scalp, nails, genitals, and skin folds can interfere with routine activities like dressing, grooming, and hygiene. Discomfort can disrupt sleep, leading to fatigue, which further diminishes quality of life. Sleep deprivation can exacerbate both physical symptoms and psychological distress, creating a cycle that compounds disease burden.[37]
-
Functional ImpairmentPsoriasis can affect fine motor skills, particularly if lesions are present on the hands or if psoriatic arthritis is involved. Nail psoriasis, for instance, may impair tasks such as typing, writing, or buttoning clothes. Joint pain and stiffness, characteristic of psoriatic arthritis, can limit mobility and make simple movements painful. This functional impairment impacts independence and productivity in both personal and professional contexts.[38,39]
Psychological and Emotional Well-being
-
Self-esteem and Body ImageThe visibility of psoriatic lesions can cause psychological distress and impact body image. Women with psoriasis may feel embarrassed, self-conscious, and stigmatized, affecting their confidence in social, professional, and intimate settings. This can result in social withdrawal and reluctance to engage in activities that reveal affected skin, such as swimming or exercising in public spaces.[40]
-
Mental Health DisordersWomen with psoriasis are at an increased risk of mental health conditions, particularly depression and anxiety. The chronic nature of psoriasis, combined with hormonal imbalances and the unpredictability of symptom flare-ups, can exacerbate these mental health challenges. Depression and anxiety are not only consequences of physical symptoms but also contribute to a cycle that can worsen psoriasis severity due to stress and emotional strain.[41]
-
Coping MechanismsSome women may develop maladaptive coping mechanisms in response to psoriasis, such as social withdrawal, substance use, or disordered eating. These behaviors can provide temporary relief from emotional pain but ultimately worsen physical health and mental well-being. Access to mental health support and counseling is crucial for promoting adaptive coping strategies and breaking this cycle.[42]
Social and Interpersonal Relationships
-
Social IsolationDue to the visibility of lesions and the fear of judgment or misunderstanding, many women with psoriasis withdraw from social activities. Misconceptions about psoriasis being contagious can amplify feelings of isolation, as friends, colleagues, or even strangers may avoid physical contact. This isolation can deepen psychological distress and reinforce negative self-image.[43]
-
Intimate RelationshipsPsoriasis can affect intimate relationships on both physical and emotional levels. Concerns about appearance, physical discomfort during sexual activity, and decreased libido (influenced by hormonal changes and psychological distress) can impact intimacy. Open communication with partners is essential for managing expectations and providing reassurance. Educating partners about psoriasis’s non-contagious nature can also foster understanding and empathy, strengthening relationships.[43,44,45]
-
Communication and EducationEducating close contacts about psoriasis and its impact can dispel misconceptions and improve social support. Friends and family who understand the chronic, non-contagious nature of psoriasis are better equipped to provide meaningful support, reducing the emotional burden and promoting acceptance.[46]
Professional and Educational Impact
-
Work ProductivityPhysical symptoms such as pain and fatigue, combined with psychological distress, can reduce productivity, increase absenteeism, and limit career opportunities. Psoriatic arthritis may further hinder workplace performance by restricting mobility and causing joint pain, especially in physically demanding jobs. Visible lesions can be particularly challenging in professions that emphasize appearance or require public interaction, as stigma and discomfort can affect performance and self-confidence.[43,47,48]
-
Discrimination and StigmaWomen with psoriasis may encounter discrimination or harassment in the workplace or educational settings due to misconceptions about their condition. Psoriasis is often misunderstood, with some perceiving it as contagious or reflective of poor hygiene, leading to prejudice. Legal protections may be necessary to address workplace discrimination, ensure fair treatment, and promote an inclusive environment.[49,50]
-
Academic ChallengesManaging psoriasis symptoms and treatment regimens can interfere with academic responsibilities, impacting performance and opportunities for advancement. For students with psoriasis, navigating treatment schedules alongside coursework and social obligations may be challenging. Educators and academic institutions that are informed about psoriasis can help provide support and accommodations, such as flexibility with assignments or exams, allowing students to manage their health without compromising their education.[51,52]
2. Fertility and Reproductive Health
Disease Severity and Systemic Inflammation
- Hormonal Disruption: Chronic inflammation can interfere with the hypothalamic-pituitary-ovarian (HPO) axis, which is crucial for regulating reproductive hormones like estrogen, progesterone, and luteinizing hormone (LH). Disruptions in this axis can lead to irregular menstrual cycles, affecting fertility by making it harder for ovulation to occur predictably.[6,8,9,25,53,54]
- Impact on Ovulation and Implantation: Inflammation may also affect the uterus and ovaries directly, impairing ovulation or creating a less hospitable environment for implantation. Studies have shown that elevated inflammatory markers (e.g., TNF-alpha, IL-6) can influence the reproductive environment, potentially lowering conception rates or increasing the risk of early miscarriage in women with chronic inflammatory conditions.[12,54,56]
Medication Effects
- Methotrexate: Methotrexate is a systemic immunosuppressive drug that is often used to treat severe psoriasis but is highly teratogenic. It interferes with folate metabolism, which is crucial for DNA synthesis and cell division, affecting both male and female fertility. Women planning a pregnancy are advised to discontinue methotrexate for at least 3 months prior to conception.[57]
- Retinoids (e.g., acitretin): Retinoids are derivatives of vitamin A that are used in psoriasis management but can cause severe birth defects if used during pregnancy. Women on retinoids are usually advised to wait at least 3 years after stopping treatment before attempting to conceive due to the drug’s long half-life.[57]
- Other Immunosuppressants: Some other medications, like cyclosporine, may be used in specific cases but require close monitoring due to potential risks to the developing fetus and possible impacts on fertility.[57] Biologic drugs such as TNF inhibitors are generally considered safer for use during pregnancy, but each case should be evaluated individually.[57]
Psychological Stress and Hormonal Balance
- Stress and the HPO Axis: Psychological stress can lead to changes in the HPO axis, impacting hormone release and potentially leading to menstrual irregularities, anovulation (absence of ovulation), or luteal phase defects (which can hinder implantation). Chronic stress activates the hypothalamic-pituitary-adrenal (HPA) axis, increasing cortisol levels. Elevated cortisol can disrupt the delicate balance of reproductive hormones, further complicating fertility.[25,53,54]
- Cyclical Impact of Flare-Ups: Psoriasis symptoms often fluctuate with hormonal changes, and flare-ups may exacerbate stress levels, creating a cyclical problem. The additional stress during flare-ups may impact reproductive hormones, increasing the likelihood of irregular periods and complicating timing for conception.[31,53]
Lifestyle Factors
- Obesity and Insulin Resistance: Obesity is prevalent among individuals with psoriasis and is a known risk factor for insulin resistance, which can contribute to polycystic ovary syndrome (PCOS). PCOS is a common endocrine disorder that can cause irregular menstrual cycles and anovulation, both of which can negatively impact fertility.[57,58]
- Smoking and Alcohol: Smoking and excessive alcohol use are also more common in individuals with psoriasis and have both been linked to decreased fertility. Smoking can lead to premature ovarian failure, reduced egg quality, and increased risk of early pregnancy loss. Alcohol, on the other hand, can interfere with hormone levels and reduce the likelihood of conception.[59,60]
- Metabolic Syndrome: Psoriasis is also linked to metabolic syndrome, which is a combination of conditions including hypertension, hyperglycemia, and abnormal cholesterol levels. Metabolic syndrome can contribute to inflammation and hormonal dysregulation, further complicating fertility and reproductive health.[57,61]
Pregnancy Planning and Management
- Preconception Counseling: Women with psoriasis should consult with healthcare providers before trying to conceive to discuss medication adjustments and other preparation steps. Discontinuing certain medications, switching to safer alternatives, or modifying the dosage under medical supervision may be necessary to ensure a safe pregnancy.[57,62]
- Management During Pregnancy: In some cases, pregnancy can improve psoriasis symptoms due to hormonal changes that favor an anti-inflammatory state. However, managing psoriasis during pregnancy can be challenging because options for systemic treatments are limited. Topical treatments are generally safer and are often preferred for controlling symptoms.[7,57,62]
6. Management Strategies
2. Personalized Treatment Approaches
- Calcineurin Inhibitors (e.g., Tacrolimus): Effective for delicate skin areas like the face and genitals, these agents modulate immune response without the same side effects as steroids, although they are usually used as second-line treatments.[57]
- Emollients and Moisturizers: Regular use of emollients helps keep the skin hydrated, reducing scaling and discomfort. Studies show that well-hydrated skin can improve the efficacy of other topical treatments.[64]
Systemic Treatments
- Methotrexate and Cyclosporine: These immunosuppressants are often used for moderate to severe cases of psoriasis but can have significant side effects, including liver and kidney toxicity. For women planning pregnancy, methotrexate is contraindicated due to its teratogenic effects.[57]
- Acitretin: A retinoid used in psoriasis treatment, acitretin is effective but also teratogenic, with pregnancy avoidance recommended for 3 years post-treatment.[57]
- Biologic Agents: Biologics, including TNF-α inhibitors (e.g., infliximab), IL-17 inhibitors (e.g., secukinumab), and IL-23 inhibitors (e.g., guselkumab), target specific immune pathways involved in psoriasis and offer targeted, effective control with fewer systemic effects. Biologics are generally considered safe but must be evaluated on an individual basis, especially for pregnant or breastfeeding women.[57]
Phototherapy
- Narrowband UVB and PUVA Therapy: Phototherapy is effective for moderate to severe psoriasis and is considered safe during pregnancy, making it a valuable option for women needing more than topical treatments. Narrowband UVB therapy has been shown to reduce flare-ups without systemic side effects, making it suitable for long-term management.[65]
Hormone-Based Therapies
- Hormone Replacement Therapy (HRT): Postmenopausal women may see some improvement in psoriasis symptoms with HRT, as estrogen can have anti-inflammatory effects. However, HRT carries risks (e.g., cardiovascular disease, breast cancer), and its impact on psoriasis varies; thorough risk assessment is essential before initiation.[34]
2. Lifestyle Modifications
Healthy Diet
- Anti-Inflammatory Diet: Diets rich in antioxidants, omega-3 fatty acids, and anti-inflammatory foods, such as fruits, vegetables and whole grains, have been associated with reduced psoriasis symptoms. Omega-3 fatty acids, found in fish and flaxseeds, have been shown to reduce systemic inflammation.[68,69]
Regular Exercise
- Physical Activity: Regular exercise improves cardiovascular health, reduces obesity risk, lowers stress levels, and improves psoriasis severity. Exercise also reduces pro-inflammatory markers, aiding in better disease management.[71]
Avoiding Triggers
- Personal Triggers: Common triggers include smoking, alcohol, allergens, and certain foods. Keeping a symptom diary to identify triggers can help in managing flare-ups more effectively. Smoking, for instance, is associated with higher psoriasis risk and severity, making cessation highly beneficial.[59,60,70,72]
2. Multidisciplinary Care
Collaborative Approach
- Team-Based Care: A multidisciplinary approach involving dermatologists, rheumatologists, gynecologists, mental health professionals, and primary care providers offers comprehensive care. This collaborative care model is critical for women with psoriasis, addressing physical symptoms, emotional challenges, hormonal influences, and reproductive health needs.[62,73,74,75]
Patient Education
- ● Self-Management Education: Educating women about how hormonal changes impact psoriasis empowers them to manage their condition proactively. Support groups, counseling, and access to educational resources can improve self-management and treatment adherence, particularly during life stages associated with hormonal changes, such as pregnancy or menopause.[46,62]
Psychological Support
- Mental Health Access: Psychological support is crucial for managing psoriasis, as the visible nature of the disease can lead to anxiety, depression, and social withdrawal. Access to mental health resources like counseling and support groups can help women manage the emotional aspects of living with a chronic skin condition.[75]
Family Planning Services
- Safe Contraception and Preconception Counseling: For women of reproductive age, coordinated care is essential to address contraception choices, preconception counseling, and pregnancy management. Many psoriasis medications are contraindicated during pregnancy, so advance planning with a healthcare provider can optimize reproductive outcomes and minimize disease activity during pregnancy.[57,62]
7. Future Directions and Research
Estrogen Receptor Studies
- Role of Estrogen Receptors in Psoriasis Pathogenesis: Estrogen has been shown to influence immune function, but the exact mechanisms remain unclear.[6,10] Estrogen receptors (ERs), specifically Erα and Erβ, are expressed on immune cells and play roles in immune regulation. Research suggests that Erα activation might have pro-inflammatory effects, while Erβ activation could be anti-inflammatory, potentially impacting psoriasis severity.[11,76]
- Targeting Estrogen Receptor Pathways: By investigating how different estrogen receptors influence immune cells, scientists may uncover specific pathways that could be modulated for therapeutic purposes. For example, selective estrogen receptor modulators (SERMs) might offer ways to manage inflammation in psoriasis without the side effects associated with broad hormone replacement therapies.[77]
Genetic and Epigenetic Factors
- Genetic Variations and Psoriasis Susceptibility: Studies have identified several genetic loci associated with psoriasis, particularly in genes related to immune responses, such as IL-23 and TNF-α pathways.[78] Research into how these genetic variations interact with hormonal changes could explain why psoriasis severity fluctuates with life stages (e.g., puberty, pregnancy, menopause).[7,9,19,78]
- Epigenetic Modifications and Hormone Sensitivity: Epigenetic changes, such as DNA methylation and histone modifications, influence gene expression without altering DNA sequences.[79] Hormones like estrogen can impact these epigenetic mechanisms, potentially affecting psoriasis severity and treatment responses.[16,80,81] Investigating how epigenetic factors modify hormonal sensitivity in individuals with psoriasis may provide insights into why some patients experience more severe symptoms and aid in the development of personalized therapies.
- Personalized Medicine: Identifying genetic and epigenetic markers linked to psoriasis severity and treatment response could facilitate personalized medicine.[81] By tailoring treatment approaches based on genetic profiles, healthcare providers may be able to optimize therapies and reduce side effects.
Longitudinal Studies
- Natural History of Psoriasis Through Life Stages: Longitudinal studies that follow women through hormonal transitions (e.g., puberty, pregnancy, menopause) are essential for understanding how hormonal fluctuations impact psoriasis.[7] Such studies can clarify if specific life stages exacerbate or alleviate symptoms, informing the timing and types of intervention strategies.
- Tracking Disease Progression and Triggers: By monitoring psoriasis progression and flare-up patterns in relation to hormonal changes, researchers can gather insights into which interventions are most effective at different life stages. For instance, such studies could identify whether hormone fluctuations are linked to periods of remission or exacerbation, guiding both timing and choice of treatments.
- Evidence-Based Treatment Timelines: Long-term data can help identify optimal treatment windows and strategies for managing psoriasis, potentially leading to interventions that are timed to life-stage transitions, such as beginning hormone-based treatments at menopause if appropriate.
Hormone-Based Treatments
- Selective Estrogen Receptor Modulators (SERMs): SERMs, which are already used in conditions like osteoporosis and breast cancer, may represent a promising area for psoriasis treatment.[77,82] These drugs selectively stimulate or block estrogen receptors, which could allow for modulation of immune responses related to psoriasis without widespread hormonal effects.[77] Trials are needed to determine the efficacy and safety of SERMs for psoriasis.
- Progesterone Analog Research: Progesterone, another key hormone, may have immunomodulatory effects that could impact psoriasis.[9] Progesterone analogs could be explored for their potential in modulating immune function, particularly during life stages where progesterone naturally fluctuates (e.g., pregnancy). Current research is limited, but understanding how progesterone and its receptors impact psoriasis could open new therapeutic options.
- Clinical Trials for Hormone-Based Therapies: Clinical trials investigating hormone-based therapies, including estrogen and progesterone treatments, are essential for understanding their effects on psoriasis.[6,9] Such trials can assess the safety, efficacy, and optimal dosing regimens of hormone therapies for patients with psoriasis, especially for women undergoing hormonal changes.
Psychoneuroimmunology Research
- Mind-Body Interactions in Psoriasis: The emerging field of psychoneuroimmunology (PNI) examines how psychological factors, neurological processes, and immune responses interact in disease contexts.[83] Stress, for example, can exacerbate psoriasis by stimulating the hypothalamic-pituitary-adrenal (HPA) axis, which releases cortisol and other stress hormones. Chronic stress also impacts immune function, leading to increased inflammatory cytokine production that can worsen psoriasis.[84]
- Role of Stress Hormones and Neurotransmitters: Research suggests that stress hormones like cortisol, as well as neurotransmitters such as serotonin and dopamine, may influence immune responses in psoriasis.[26,27] This connection indicates that stress reduction and psychological interventions may play important roles in managing psoriasis, especially given the skin-brain connection.[85] Investigating these pathways could lead to novel, holistic approaches that combine pharmacological and psychological therapies.
- Interdisciplinary Treatment Approaches: Given the complex interactions between the mind and immune function, interdisciplinary approaches that include mental health support alongside dermatologic treatment may improve outcomes. This approach might involve cognitive-behavioral therapy (CBT), mindfulness-based stress reduction, and other interventions aimed at reducing stress and improving mental well-being.[66,67,75]
