This study found that finasteride treatment in males with androgenetic alopecia was linked to significant changes in sperm parameters and increased testosterone levels, but no sexual dysfunction was observed, and sperm parameters returned to baseline after treatment stopped.

This study found that salivary testosterone levels were significantly lower in oligospermic and azoospermic men compared to normal men, suggesting its potential use in assessing male androgen status.

Among females with nonclassical 21-hydroxylase deficiency, this study found that low-dose glucocorticoid treatment improved fertility outcomes by increasing pregnancy and live birth rates while reducing miscarriage rates.

This study highlights that hirsutism in women, most commonly caused by polycystic ovary syndrome, should be evaluated with tools like the Ferriman–Gallwey score and total testosterone measurements, and managed using methods like hair removal and combined oral contraceptives when fertility preservation is not a priority.

This article reviews contraceptive options for individuals on testosterone gender-affirming hormone therapy, highlighting unique risks and benefits for this population, but it reports no new clinical findings.

This review discusses the effects of 5ARI drugs on male reproductive parameters, reporting potential decreases in sperm count and motility more significantly in men with pre-existing oligozoospermia, but does not provide fertility outcomes.

This review discusses phenotypic differences in testosterone production between mice and humans with HSD17B3 deficiency and reports no new findings; the authors highlight potential pathways and enzymes involved in testosterone synthesis.

This animal study found that testosterone treatment increased vas deferens fluid secretion rate in rats, with potential implications for male fertility through the upregulation of AQP-1, 2, and 9 proteins.

This pharmacovigilance study identified 19 drugs with high potential risk for causing male infertility, including hormonal agents, antineoplastic drugs, and antidepressants, emphasizing the need for fertility counseling and possible sperm cryopreservation in reproductive-age males before using such treatments.

This study found that both Clomiphene Citrate and Human Chorionic Gonadotropin were effective in restoring testosterone levels in men with hypogonadism, as demonstrated in a short-course randomized study.

This study found that steroid reproductive hormones such as estradiol and testosterone can be preserved and analyzed in archaeological human hair, providing new insights into ancient health and fertility.

This study found that finasteride reduced sperm count, motility, and levels of reproductive hormones, indicating negative effects on fertility in albino male rats.

This narrative review highlights that declining testosterone levels are a complex public health issue potentially influenced by modifiable lifestyle factors and environmental stressors, suggesting integrated strategies may be needed to address the trend's impacts on health.

This study found that administering testosterone to pregnant rats altered connexin 26 and connexin 43 expression in the uterus, which could disrupt embryo implantation and cause early pregnancy loss.

This study demonstrated that cortisol, estradiol, and testosterone are preserved in archaeological human hair, allowing for the analysis of ancient stress and reproductive hormone patterns.

This study found that finasteride induced infertility and increased endoplasmic reticulum stress in rats, but these effects were mitigated by DA-9401 administration.

This study found that in male rats, finasteride significantly decreased spermatogonia and primary spermatocytes numbers and increased Leydig cells, but did not affect overall testis histology or spermatogenesis.

This study found that dual 5α-reductase inhibition in rats led to decreased sperm motility and altered morphology, resulting in subfertility.

This review summarizes research on androgens' roles in female reproductive function, noting their impact on IVF outcomes and the development of PCOS, and highlights the need for mechanism-based therapies.

This study reported that BRL 7660 significantly reduced sebum secretion and acne symptoms in human studies with topical administration, but the placebo effect and commercial pressures halted further investigations.

This study developed two highly reliable Arabic HRQoL questionnaires for evaluating quality of life in married and unmarried women with polycystic ovary syndrome.

This article reviews current diagnostic methods and treatments for hair loss, including FDA-approved drugs and surgical options, but reports no new research findings.

This review discusses recent advancements in understanding and managing congenital adrenal hyperplasia, including improvements in screening, diagnostics, and potential genetic and cell-based treatments, but reports no new clinical findings.

This study updates guidelines for evaluating and managing male infertility, including revised testing recommendations for Y-chromosome microdeletions, use of pelvic MRI, and testicular sperm in nonazoospermic males.

This review discusses the various phenotypes and diagnostic challenges of polycystic ovary syndrome, highlighting its complex pathophysiology and associated health risks, and reports no new clinical results.

This review discusses the pathophysiology, diagnosis, and treatment of congenital adrenal hyperplasia, but reports no new research results.

This review discusses the diagnosis, management, and hormone treatment of transsexual individuals, and examines the risks and effects of cross-sex hormone therapy without presenting new clinical results.

This study suggests that polycystic ovary syndrome symptoms are uncommon among women with metabolic syndrome, indicating it may represent only a specific subset within the broader context of metabolic syndrome.

This study found that dual 5α-reductase inhibitors in rats decreased sperm quality and led to reduced pregnancy success, suggesting potential for use in male contraception.

This article discusses the challenges in diagnosing non-classical congenital adrenal hyperplasia and emphasizes personalized treatment approaches, reporting no new clinical results.
