Does the male gonad secrete something that affects male differentiation? In this experiment, the testes were removed from a developing fetus and the subsequent development of the ducts was noted as follows: Experiment Mullerian Wolffian Normal male - + Remove testes + - What would you conclude now about the role of the testes in causing differentiation of the ducts in males?

Outline the roles of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in the ovarian cycle of a human female.
Label the early development stages shown in the following diagram.
Figure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.
In 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?
Which 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?
Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Figure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estrogen are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.
If fertilization occurs, the corpus luteum continues to produce hormones under the direction of Human Chorionic Gonadotrophin (HCG), which is produced by the embryo. By the third month, what begins to produce estradiol and progesterone?
Follicle cells left behind after ovulation A)are shed during menstruation. B)become the corpus luteum, which secretes steroid hormones. C)become the placenta, which secretes human chorionic gonadotropin. D)become the corpus luteum, which secretes luteinizing hormone.
All of the followings are correct about female reproductive system except----------------.A. At any one time, ovaries contain follicles and corpora lutea in various stages of developmentB. LH is secreted from Theca cells under the influence of GnRHC. FSH is secreted from the anterior pituitary glandD. Estrogen and FSH further stimulate granulosa cell differentiationE. Progesterone is secreted from the corpus Luteal cell
