Content: is a glycoprotein (beta-globulin) produced by the Sertoli cells in the seminiferous tubules of the testis that binds specifically to testosterone & dihydrotestosterone (DHT). The higher levels of these hormones enable spermatogenesis in the seminiferous tubules and sperm maturation in the epididymis
11.22. Discuss the role of the hormone Inhibin in the feedback process, what cell secretes it and why, what are its target cells? ...
11.23. Describe testosterone in terms of its chemical makeup (ie is it amino acid, protein or steroid) and how this affects its method of transport in the blood and method of action on target cells. a steroid hormone from the androgen group
Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT), DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T. T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects. 11.24. Testosterone is an important hormone in the male reproductive system, discuss the effects of this hormone in relation to the seminiferous tubule and the whole body? ...
