Chapter 27, Problem 5ILQ
A baby’s gender is determined at conception, and the different genitalia of male and female fetuses develop from the same tissues in the embryo. View this animation (http://openstaxcollege.org/l/fetus) that compares the development of structures of the female and male reproductive systems in a growing fetus. Where are the testes located for most of gestational time?

Compare oogenesis to spermatogenesis. How are the two processes similar? How do they differ? (Consider both follicle and sperm structure throughout development as well as the timing of the stages.)
Describe the development of an oocyte from primordial follicle to when it is released at ovulation. How do hormones contribute to this progression? Describe the development of a spermatogonia to a spermatozoa. How do hormones contribute to this progression? What is the function of Sertoli and Leydig cells?

What kind of information does such a method provide about the likelihood of getting pregnant?arrow_forwardWhich oocyte stage is ovulated? What happens to it if it encounters a sperm cell there? What happens if it does not meet up with sperm?arrow_forward
- Why is it difficult to find both a corpus luteum and corpus albicans on the same slide? What is the function of the secondary oocyte? What is fertilization? Describe the fate of corpus luteum if: pregnancy occurs pregnancy does not occurarrow_forwardDescribe the development of reproductive organs in a fetus of each gender. Which genes, gene products, and hormones are involved in the sex differences? Which sex- related hormones are circulating in high concentrations in a pregnant woman compared to a nonpregnant woman? Do these hormones cross the placenta (if you are uncertain, consider hormone chemical class relative to membrane permeability to make an educated guess)? Assuming these hormones do cross the placenta, how do they affect the hormonal environment inside the fetus, and how does this relate to fetal reproductive development?arrow_forwardDarcy 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_forward
- Emily and her husband are thrilled as they peer into Emily's uterus by means of an ultrasound. The physician reports that the pregnancy appears normal and that their baby's organs, spine, and arms and legs are developing as expected. Given this information, the current stage of prenatal development is the embryonic period germinal period zygotic period fetal stage placentaarrow_forwardWhat happens if an oocyte combines with sperm? Describe the processes involved in implantation. Mention what is occurring, where it is occurring, and any significant hormones involved. How does the zygote make its way through the uterine tube? Women who smoke cigarettes have an increased risk of ectopic pregnancy because the chemicals they absorb paralyze cilia all through the body. Explain.arrow_forwardIn severe cases of endometriosis, endometrial tissue is found within the peritoneum. How can endometrial tissue from the uterus end up in the peritoneum?arrow_forward
- Describe the 28-day uterine cycle in females, citing important timeframes/hormones/events in the cycle. Your response must include the difference between fertilization occurring and fertilization not occurring throughout this cycle and how that would effect the cycle's "completion" (What I mean by this is describe the entire cycle and how it would change if a zygote is successfully formed and implanted into the uterus resulting in pregnancy)arrow_forwardWhich of the following statements does NOT correctly describe the events following fertilization? Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.arrow_forwardProgesterone, estrogen, prostaglandins, and oxytocin all have important roles that influence parturition. For each of thesubstances listed, describe whether it has a stimulatory or inhibitory effect on the uterus.arrow_forward
