- Where (specifically) does fertilization take place in the body? When the zygote divides, is it using meiosis or mitosis?arrow_forwardWhat is the most significant difference in the process of gametogenesis comparing oogenesis with spermatogenesis?arrow_forwardOogenesis 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.arrow_forward
- What is the importance of Meiosis to Oogenesis and Spermatogenesis?arrow_forwardWhat are two important differences between the processes of spermatogenesis and oogenesis in animals?arrow_forwardFertilization is the fusion of haploid gametes, ovum and spermatozoon, to form a diploid zygote. Discuss physiologic mechanisms in the male and the female that make sure that indeed only one sperm fertilizes a single eggarrow_forward
- In-vitro fertilization occurs in the laboratory. The resulting embryos remain in a laboratory culture for up to six days before being transferred to the potential mother. If fertilization had occurred naturally (i.e., inside the female reproductive system instead of in-vitro), where would the embryo be and what developmental processes would it be undergoing during those first six days of development?arrow_forwardIf spermatogenesis is normal and all cells survive, how many sperm cells will be formed from 100 spermatogonia?arrow_forwardWhich of the following is true about Organogenesis? Choose all possible answers. anterior pituitary gland releases FSH and LH that drives ovarian development is the process by which mature female gametes, or ova, develop from germ cells. begins at puberty LH surge causes the oocyte to mature. After the secondary oocyte is released from the ovary, meiosis is completed.arrow_forward
- Darcy and Raul are having difficulty conceiving a child. Darcy ovulates every 28 days, and Raul’s sperm count is normal. If we could observe Raul’s sperm about an hour after ejaculation, however, we’d see that they appear to be moving only sluggishly. When Raul’s sperm eventually encounter Darcy’s oocyte, they appear to be incapable of generating an adequate acrosomal reaction. Which process has probably gone wrong?arrow_forwardAfter 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.arrow_forwardIf fertilization occurs, the corpus luteum continues to produce hormones under the direction of Human Chorionic Gonadotrophin (HCG), which is produced by the embryo. By the third month, what begins to produce estradiol and progesterone?arrow_forward
