Watch this series of videos (http://openstaxcollege.org/l/oocyte) to look at the movement of the oocyte through the ovary. The cilia in the uterine tube promote movement of the oocyte. What would likely occur if the cilia were paralyzed at the time of ovulation?
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.

A spermatogonial cell undergoes mitosis before entering the meiotic cell cycle en route to the production of sperm. However, during mitosis the cytoplasm fails to divide, and only one daughter cell is produced. A resultant sperm eventually fertilizes a normal ovum. What is the chromosomal complement of the embryo?
Label the parts of the male reproductive system and state their functions.
