- A study divides healthy females into two groups (A and B). Both groupsare composed of those who have been sexually active for at least 2 yearsand are not pregnant at the beginning of the experiment. The subjectsweigh about the same amount, and none smoke cigarettes, althoughsome drink alcohol occasionally. Group A individuals receive a placeboin the form of a sugar pill each morning of their menstrual cycles. GroupB individuals receive a pill containing estrogen and progesterone eachmorning of their menstrual cycles. Then plasma LH levels are measuredbefore, during, and after ovulation. The results are as follows:Group 4 Days BeforeOvulationDay ofOvulation4 Days AfterOvulationA 18 mg/100 mL 300 mg/100 mL 17 mg/100 mLB 21 mg/100 mL 157 mg/100 mL 15 mg/100 mLThe number of pregnancies in group A is 37/100 females/year.

- _____ is a form of 46,XY intersex that affects chromosomal males. It is by far the most common form of 46,XY intersex. These individuals have testes that produce testosterone, but their bodies lack working androgen receptors. When these individuals are born they often have female-typical genitalia, and they develop female secondary sex characteristics at puberty. They also tend to develop a female gender identity.
