🤖 Smallpdf.com: # Summary of Male Reproductive System and Testosterone - **Testosterone Production**: Secreted by Leydig cells in testes; predominant androgen. - **Metabolism**: 97% binds to plasma proteins; converted to dihydrotestosterone in target tissues. - **Functions**: Develops male characteristics, influences muscle mass, bone density, and metabolism. - **Effects**: Promotes hair growth, voice deepening, and skin thickness; can cause acne. - **Estrogen Production**: Small amounts produced, primarily from testosterone conversion. - **Mechanism**: Acts via increased protein synthesis in target cells, influencing primary and secondary sexual characteristics. 🙂: What role do estrogens play in male spermiogenesis? 🤖 Smallpdf.com: Estrogens play an important role in male spermiogenesis by being present in high concentrations within the fluid of the seminiferous tubules. They are believed to be formed by Sertoli cells through the conversion of testosterone to estradiol, which supports the maturation and development of sperm. Thus, estrogens contribute to the overall process of sperm formation and maturation in males. 🙂: What role do Leydig cells play in testosterone production? 🤖 Smallpdf.com: Leydig cells are responsible for the production of testosterone in the testes. They are located between the seminiferous tubules and secrete large quantities of testosterone during fetal development, after birth, and post-puberty. Additionally, Leydig cells can continue to produce testosterone even when germinal epithelium is damaged, such as after x-ray treatment or excessive heat.
