Textbook Question
Chapter 28, Problem 1CT
Joe and Jane desperately want to have children, and although they have tried for 2 years, they have not been successful. Finally, each of them consults a physician, and it turns out that Joe has oligospermia (low sperm count). He confides to you that he doesn't understand why this would interfere with his ability to have children since he remembers from biology class that it only takes one sperm to fertilize an oocyte. What should you tell him?

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?
Isabella, 28, and Omar, 30, have been together for three years. A year ago, they decided they wanted to have a baby, and they stopped using birth control. At first, they did not pay attention to the timing of their sexual activity in relation to Isabella’s menstrual cycle, but after six months passed without Isabella becoming pregnant, they decided to try to maximize their efforts.
They knew that in order for a woman to become pregnant, the man’s sperm must encounter the woman’s egg, which is typically released once a month through a process called ovulation. They had also heard that for the average woman, ovulation occurs around day 14 of the menstrual cycle. To maximize their chances of conception, they tried to have sexual intercourse on day 14 of Isabella’s menstrual cycle each month.
After several months of trying this method, Isabella is still not pregnant. She is concerned that she may not be ovulating on a regular basis because her menstrual cycles are irregular and often…
A male patient is upset by all the testing that is occurring to determine why he and his wife have not conceived. He is sure she is the one with the problem.
After all the testing, it is discovered that the man has a low sperm count. What questions might the nurse ask to determine the source?

- A friend in your dormitory, a freshman, tells you that she just discovered she is 3 months pregnant. You know that since she came to college she has been experimenting with recreational drugs. Circle the best advice you could give her, and explain your choice. (a) She must stop taking the drugs, but they could not have affected her fetus during these first few months of her pregnancy.

- If spermatogenesis is normal and all cells survive, how many sperm cells will be formed from 100 spermatogonia?arrow_forwardA couple living in Florida is trying to have a baby, but they are having trouble getting pregnant. The male is very light skinned yet enjoys spending as much time as possible outdoors in the sun. From the male's perspective, why might he be contributing to the trouble with getting pregnant? Excessive ultraviolet light exposure can reduce folate levels, and folate is required for normal sperm development. Excessive heat from the sunlight inhibits normal sperm production; thus, he probably does not have enough sperm. The male does not have enough melanin production to support normal sperm development. Excessive sunlight exposure can rapidly increase folate levels, which then inhibits normal sperm development. Normal sperm development occurs best in colder temperatures; thus, living in Florida he has a reduced chance of getting his partner pregnant.arrow_forwardEmily 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_forward
