- Describe the stages of labor.arrow_forwardIn the fertility awareness method of birth control, a woman gauges her monthly fertile period by monitoring changes in the consistency of her vaginal mucus. What kind of information does such a method provide about the likelihood of getting pregnant?arrow_forwardA 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. (b) Harmful substances usually cannot pass from mother to embryo, so she can keep using drugs. (c) There could be defects in the fetus, so she should stop using drugs and visit a doctor as soon as possible. (d) If she has not taken any drugs in the last week, she is OK.arrow_forward

- Describe 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_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_forwardHow is labor induced if a woman’s pregnancy extends past her due date?arrow_forward
