This review discusses the biology of spermatogenesis and male reproductive toxicology but reports no new research findings.

This study found that an educational program significantly improved knowledge about polycystic ovary syndrome and its prevention among adolescent girls at a selected college.

This article summarizes findings on the role of androgens and estrogens in male reproductive tissues across species, highlighting the roles of hormone metabolism, receptor distribution, and stress-induced changes.

This study reviews the mechanisms by which SARS-CoV-2 may impact male fertility, noting potential disruptions in spermatogenesis and hormone secretion, and underscores the need for follow-up in recovered men.

This review suggests that telocytes in male reproductive organs help organize tissue structure and paracrine factors, impacting organ development and pathology, but more research is needed on their molecular pathways.

In this study on Danio rerio, researchers found that exposure to titanium dioxide nanoparticles did not affect embryonic development but altered the structure of male gonads, acting as potential endocrine disruptors with androgenic activity.

This review highlights potential negative impacts of certain medications on male fertility, such as hormonal disruption and germ cell toxicity, emphasizing the importance of clinicians being aware of these effects to advise on safer alternatives.

This review covers cell transplantation methods for genitourinary reconstruction, discussing tissue sources and complications but presenting no new clinical findings.

This study found that finasteride and minoxidil act as hormone disruptors in mice, with finasteride having a more significant association with reproductive injuries, such as damage to the epididymis and reduced semen volume.

This systematic review reports that HAIR-AN syndrome, characterized by severe insulin resistance, hyperandrogenism, and distinctive skin issues, significantly impacts obese women and can improve with treatments like metformin, emphasizing the importance of targeted management to reduce metabolic complications.

This study concluded that clomiphene citrate is generally preferred over metformin for inducing ovulation in obese women with PCOS, despite low-quality evidence indicating metformin may be superior to placebo for live births.

This study found that lower salmon availability was associated with higher stress hormone levels in grizzly and black bears, influencing their physiological responses and competitive behaviors.

This systematic review concluded that 5 mg of oral finasteride per day could be an effective and safe treatment for female pattern hair loss in normoandrogenic women, particularly when combined with other medications.

In this study, a modified Ferriman-Galwey score greater than 4 was found to be effective for diagnosing hirsutism in Asian women, highlighting key areas such as the upper lip, thighs, and lower abdomen.

In this study, researchers found that both minoxidil and finasteride, commonly used for treating androgenetic alopecia, pose risks to male reproductive health due to their endocrine-disrupting effects and impact on testicular morphology and function, suggesting the need for further research into their reproductive safety.

In this study, topical application of a 10% minoxidil lotion on mature rats over 72 days was associated with reduced testis and epididymis mass and sperm motility, indicating potential gonadotoxic effects.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This review identified and evaluated polycystic ovary syndrome models of care, finding that only three fully aligned with international guidelines and generally received positive feedback on satisfaction; just one showed an impact on patients' BMI.

In this systematic review, researchers observed that Toxoplasma gondii infection is associated with alterations in testosterone levels, generally increasing in humans but showing mixed effects in animals, highlighting a complex relationship that warrants further investigation.

This review discusses the harmful effects of coloring shampoos containing trihydroxybenzene on the scalp-skin barrier and emphasizes the need for safer ingredient selection to prevent side effects.

This review discusses meditation and Suryanamaskar for women with PCOS and reports no new clinical results; the authors emphasize Suryanamaskar's potential benefits and the need for lifestyle modifications.

This study describes the development of a prototype clinical expert system that uses a belief rule-based inference methodology to improve the risk stratification and diagnosis of polycystic ovary syndrome by addressing uncertainties in clinical data and domain knowledge.

This study found that finasteride was associated with more reproductive adverse effects, including sexual dysfunction in men and fetal harm in women, compared to minoxidil in reported alopecia cases.

This study observed that smallholder cattle farmers in West Nusa Tenggara, Indonesia using leucaena as feed managed more cattle and focused more on fattening rather than breeding, but leucaena toxicity led to illnesses such as hair loss and, in a few cases, reproductive issues.

This study observed that women with cicatricial hair loss had an increased risk of hypertension, which may share overlapping biological origins.

This study suggests that gender-affirming testosterone therapy in transgender men is generally safe and effective with adequate screening and monitoring, although high-quality long-term studies are lacking.

This review discusses nitric oxide's physiological roles and the development of strategies for delivering it exogenously, without presenting new clinical results.

This integrative review found that while hormone therapy, under proper medical supervision, can improve quality of life by treating conditions like muscle and bone mass loss, using these hormones without clinical need poses serious risks to neurological, cardiac, hepatic, renal, and reproductive health.

This review highlights the significant risks posed by mercury to the endocrine system, including disruptions in hormone synthesis and regulation, stress response, and potential reproductive dysfunction, while noting the need for further research on dose-response relationships and long-term impacts.

This article discusses the potential of acupuncture as a complementary or alternative therapy for PCOS, highlighting experimental evidence of its positive effects on reproductive and metabolic function, but reports no new clinical results.
