Fadrozole and finasteride change gene expression related to sex hormones and thyroid hormones in frog larvae development.

Finasteride exposure harms tadpole reproduction and hormone balance.

Scientists restored fertility in male mice lacking a key fertility gene by using a modified gene.

The study concludes that a genetic mutation in TFM mice leads to reduced androgen receptor activity, affecting the body's response to male hormones.

New genes and pathways are important for testosterone production and male sexual development.

More research is needed to confirm sperm DNA fragmentation as a reliable tool for diagnosing male infertility.

Androgens and estrogens are crucial for male reproductive health, affecting hormone levels and tissue function.

Fadrozole and Finasteride change frog sex ratios and cause intersex animals with altered gene expressions.

Finasteride treatment changes Cx43 in rat testes, possibly causing fertility issues.

Dihydrotestosterone has a reduced effect on muscle-building in people with testicular feminization syndrome, especially after their gonads are removed.

Diagnosing sex development disorders requires combining medical history, physical exams, imaging, lab tests, and genetic data.

A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.

Testosterone changes how certain channels work in male rat reproductive tracts, affecting fertility-related fluid balance.

DHT affects testicular development and regulates spermatogenesis in some fish.

The development of breeding tubercles in male zebrafish relies on a specific enzyme that processes hormones.

The testes produce sperm and hormones essential for male development.

Finasteride, at doses of 5mg or higher, may negatively affect male fertility by reducing the expression of certain genes involved in sperm production.

Blocking a specific enzyme in male rat fetuses leads to the development of nipples and feminized genitalia.

Testosterone significantly affects urination differences between male and female mice.

The document explains how sperm cells are produced, the role of testosterone in this process, and how toxins can reduce sperm count and fertility.

Androgens regulate Sertoli cells and affect fertility through specific receptors and coregulators.

Young and adult hamsters both respond similarly to testosterone and finasteride treatments, but young hamsters aren't good for testing the inhibitory activity of a specific enzyme.

Most zinc in rat sperm is in the tail, linked to structures similar to hair keratin.

DHT is crucial for urethral formation, and its disruption can affect masculinization and lead to hypospadias.

A small BOTOX dose improved sperm production and movement in older mice.

Finasteride affects offspring's antioxidant enzymes in epididymis, possibly disrupting sperm maturation.

COVID-19 can harm male fertility by reducing sperm stem cells and damaging testicular function.

Mouse genital development depends on male or female hormones for specific features.

Impaired androgen production in 46,XY DSDs causes ambiguous genitalia and requires long-term care.
