Describe the role of pregnancy hormones during human pregnancy. What hormones prepare the mammary glands for lactation and what hormones continue to be important during this process?
If the ovum is not fertilized, the corpus luteum regresses, and the endometrium sloughs off to result in the first day of menstrual bleeding. The latter event would be duplicated, even if fertilization occurred, if receptors for which of the following hormones were occupied by an antagonist? A) Dehydroepiandrosterone B) Estradiol C ) Estriol D) Estrone E) Progesterone

Each of the four female reproductive hormones ( FSH, LH, estrogen & progesterone) have specific roles or function to complete to ensure a successful pregnancy. While these hormones may be released at a different time during an average 28-day cycle there are key times in the cycle where their release is critical in ensuring a successful pregnancy. Which of the following list the order of hormonal release from 0-28 requirements to support the fertilization and implantation of the ovum? Select one: A. FSH, estrogen, LH, progesterone. B. FSH, estrogen, progesterone, LH C. LH, FSH, estrogen, progesterone D. FSH, LF, estrogen, progesterone
If a genetic female fetus is exposed to testosterone in utero, would that individual develop a complete male phenotypic sex, partial male phenotypic sex, or a normal female phenotypic sex? Explain your answer, describing the sex phenotype of the gonads, internal genital ducts and external genitalia. What would the developmental outcomes be if the fetus were instead exposed to dihydrotestosterone in utero?
