In this cohort study of young Danish men, self-reported older age at voice break was linked to certain reproductive hormone changes that suggest reduced male fecundity, but associations with semen characteristics and testicular volume were not statistically significant.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This report describes a 19-year-old male with 49,XXXXY syndrome receiving testosterone replacement therapy, which led to improvements in reproductive development, metabolism, and social interaction after a year of treatment.

This study found that exposure to certain pesticides may be associated with delayed sexual maturation in adolescent males.

This study found that boys in Mexico City with selenium intake below the recommended dietary allowance had lower odds of progressing to advanced stages of pubertal development, while no association was observed in girls.

This review discusses therapeutic options for pubertal induction in congenital hypogonadotropic hypogonadism, focusing on recombinant gonadotropins, and highlights the need for larger randomized trials to determine optimal treatment strategies.

In this study of male patients with 46,XY 5α-reductase type 2 deficiency, DHT therapy was effective in achieving penile enlargement during infancy, while testosterone replacement therapy proved more beneficial during puberty, possibly due to increased conversion to DHT.

Using hair loss drugs finasteride and dutasteride may cause sexual side effects.

Larger prostate size in older men may be linked to poorer semen quality and fertility issues.

Man experienced post-finasteride syndrome symptoms after using finasteride and dutasteride for hair loss.

This study found that tildacerfont treatment in males with congenital adrenal hyperplasia reduced androgen levels and improved markers of testicular function, suggesting potential benefits for male reproductive health.

In this study, G. brevis and M. myristica, alone or together, improved hematological and testicular antioxidant parameters in male rats with finasteride-induced reproductive toxicity, showing potential protective effects against oxidative stress and supporting therapeutic use for related male reproductive disorders.

In this study, oral melatonin given to male Pomeranian dogs with Alopecia X improved semen quality and testicular blood flow in a dose-dependent manner, but altered hormonal balance, indicating complex effects that require further investigation for long-term implications.

In this rat study, finasteride treatment significantly reduced body, testis, epididymis, and prostate weights and affected testicular histology, indicating potential negative impacts on testicular function.

This study concluded that Buserelin can effectively inhibit gonadal activity in children with central precocious puberty over 18 months, potentially improving final height predictions with prolonged treatment.

This study reports a rare case of polyorchidism in a 96-year-old male cadaver, suggesting a new classification based on anatomical and histological findings to aid in accurate diagnosis.

This study found that men with early-onset androgenetic alopecia who also met criteria for the male PCOS-equivalent may have impaired gonadal steroidogenesis, suggesting increased risk of future gonadal dysfunction.

This chapter reviews the biosynthesis, mechanism of action, and therapeutic effects of testosterone and related androgens, but reports no new research findings.

This study found that in male rats, hesperidin co-administration ameliorated finasteride-induced testicular toxicity by reducing oxidative stress and improving antioxidant status, sperm parameters, and enzyme activity compared to finasteride treatment alone.

This study examined the most common chemotherapy side effects among patients with prostate, bladder, and testicular cancer, noting hair loss, fatigue, and decreased appetite as frequent symptoms.

In this study, autologous intratesticular PRP injection was found to be a feasible and well-tolerated procedure with low complication rates and quick recovery, but the authors indicated that current evidence is insufficient to confirm its effectiveness for mTESE.

This study found that combining Flutamide and an LHRH agonist in adult male rats effectively inhibited prostatic growth and reduced androgen-sensitive prostatic activity markers to levels similar to castrated rats.

This dissertation found that finasteride reduced prostate volume by 6.3% and total serum PSA by 10.51% in young patients over one year.

This study found that chronic exposure to finasteride did not significantly impact spermatogenesis in rats.

This study found that blocking androgen receptors inhibits testicular descent in rats more effectively during the early stages of gubernacular outgrowth than inhibiting 5a-reductase.

This article discusses laboratory and physical markers that may help detect androgenic anabolic steroid abuse in athletes and reports no new primary research results.

The document concludes that accurate diagnosis of male and female gonadal disorders is crucial for effective treatment and better patient outcomes.

In this study, the authors concluded that COVID-19 may not cause direct long-term harm to testicular function, but temporary indirect effects could occur, suggesting a possible delay in pursuing parenthood post-recovery.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

This review discusses recent data on the use of anabolic-androgenic steroids and other steroid compounds and reports no new clinical results.
