At puberty, the testes contain a finite number of cells and producean enormous number of sperm cells during the life span of a male.Explain why testes do not run out of spermatogonial cells

as possible, because a In oogenesis it is important to produce an egg with as much fertilized egg must repeatedly and produce numerous daughter cells.

Reproductive physiology (human)     a) At the time of ovulation, the released ovum (egg) has completed both meiosis I and meiosis II.   b) Because the corpus luteum (CL) is rescued from atresia by hCG early in pregnancy, the CL continues to produce progesterone throughout the 9 months of a normal pregnancy.   c) Late in the follicular phase, estrogen participates in a positive feedback loop that leads to a surge in luteinizing hormone and ovulation.   d) Both (a) and (b) are correct and (c) is incorrect   e) Statements (a), (b) and (c) are all correct

Describe in detail spermatogenesis

A professional male athlete has been taking a synthetic testosterone supplement for several months. He and his wife have been trying to have a baby, with no success, and have decided to begin treatment for infertility. Before testing the man’s sperm, the doctor discovers that the man’s LH levels are very low. Why do you think his LH le count vels are low? Would low LH levels affect sperm production?

Oogenesis is the process of female gamete (ovum or egg) production in animals. Spermatogenesis is the process of male gamete (sperm) production in animals. Provide two major differences between the processes of oogenesis and spermatogenesis.  Provide one similarity between the processes of oogenesis and spermatogenesis.

What means to retain the ability to become any cell type—including germ-line cells and gametes—when exposed to the appropriate signals in a developing embryo?

Puberty in females begins with the first menstrual cycle the development of breasts an increase in GnRH increased estrogen from follicular development the completion of meiosis in oogenesis

From what I understand, menopause occurs after depletion and atresia of ovarian follicles. So, would something that depletes follicles at a faster rate than normal, such as fertility treatments, lead to early menopause?

After learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy? Feel free to check with your older friends, doctors, nurses, or anyone who you feel comfortable talking about this.
