Title: Explain the roles of the hormones GnRH, FSH, and LH, in the male and female reproductive systems. ... Post by: noah.ratliff on Mar 31, 2018 In both males and females, gonadotropin-releasing hormone (GnRH) is secreted by the hypothalamus gland and acts on the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH) into the bloodstream. While these two hormones were named for their function in females, they both exert effects on the male reproductive system as well. In females, the target of FSH and LH is the ovary: FSH stimulates follicular growth and maturation, and LH triggers ovulation and subsequent formation of the corpus luteum from the remaining follicle cells. In males, the target of the two gonadotropins is the testis. FSH stimulates Sertoli cells to secrete a protein and other molecules that are required for spermatogenesis, while LH stimulates the Leydig cells to secrete testosterone. Both spermatogenesis and oogenesis are types of gametogenesis, or gamete production. Spermatogenesis (sperm production) occurs in males in the seminiferous tubules of the testes, while oogenesis (egg formation) occurs in the ovaries of females. The two processes involve early mitotic and late meiotic divisions. Spermatogenesis and oogenesis differ in many respects. These include the following: 1) Spermatogenesis begins at puberty and continuous throughout the male's lifetime. Oogenesis, on the other hand, begins during embryonic development and stops at menopause. 2) While spermatogenesis is a continuous uninterrupted process, oogenesis undergoes two long pauses (one in meiosis I and the other in meiosis II). Indeed, oogenesis is not completed until fertilization occurs. 3) Spermatogenesis involves equal cytoplasmic divisions that result in four equivalent and functional gametes. Oogenesis results in one large functional gamete and up to three very small nonfunctional polar bodies. 4) Spermatogenesis results in the production of about 130 million sperm per day. Oogenesis, on the other hand, produces an average of one egg per month Title: Explain the roles of the hormones GnRH, FSH, and LH, in the male and female reproductive systems. ...
