testosterone Leydig cells Sertoli cells seminiferous tubules germ cells spermatogenesis male reproductive toxicology

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

The document from 2013 provides a brief review of the complex biology of spermatogenesis, the process of sperm cell production. It explains that under pituitary stimulation, Leydig cells synthesize and secrete testosterone, which is necessary for spermatogenesis and much of male characteristics. Sertoli cells inside the seminiferous tubules support and nurture the germ cells during their differentiation. The document also discusses male reproductive toxicology, which is the study of how toxicants affect the male reproductive system. It mentions that most lesions in this tract will reduce the number or function of the germ cells produced, leading to a reduced sperm count and fertility. The document also reviews a few classic male toxicants and their subcellular targets.

Testosterone within the normal range does not significantly contribute to male pattern baldness (MPB); DHT is the main factor that can be controlled. Genetics play a crucial role in hair loss, and treatments like finasteride and dutasteride, which block DHT, can help despite potentially raising testosterone levels.

in Research/Science 82 upvotes 1 year ago

The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.
