Which one of the following is NOT the function of Leyding cells? |
Synthesis Androgens Secretes Androgens Immunologically competent cells are present in it Stimulate secretion of some factors which help in the process of Spermiogenesis |
Stimulate secretion of some factors which help in the process of Spermiogenesis |
The correct answer is Option (4) - Stimulate secretion of some factors which help in the process of Spermiogenesis Spermatogenesis starts at the age of puberty due to significant increase in the secretion of gonadotropin releasing hormone (GnRH). This is a hypothalamic hormone. The increased levels of GnRH then acts at the anterior pituitary gland and stimulates secretion of two gonadotropins – luteinising hormone (LH) and follicle stimulating hormone (FSH). The regions outside the seminiferous tubules called as interstitial spaces, contain small blood vessels and interstitial cells or Leydig cells. LH acts at the Leydig cells and stimulates synthesis and secretion of androgens. Androgens, in turn, stimulate the process of spermatogenesis. Leydig cells synthesise and secrete testicular hormones, called as androgens. Other immunologically competent cells are also present. FSH acts on the Sertoli cells and stimulates secretion of some factors which help in the process of spermiogenesis. |
