48. Semen nourishes and transports sperm cells. It also neutralizes and lubricates the female
reproductive tract during sexual intercourse. Three types of glands add their secretions to
spermatozoa from the testes to form semen. These glands are the seminal vesicles,
prostate, and bulbourethral (Cowper) glands.
49. LH controls hormone production in both males in females. In males, LH stimulates
testosterone secretion from interstitial cells. In females, LH controls progesterone release
from the corpus luteum. LH also directly regulates elements of gametogenesis in females,
since LH stimulates the release of the gamete from the ovary (ovulation), and maintains
the corpus luteum. LH plays an indirect role in male gametogenesis, since LH-induced
testosterone is involved in the maturation of spermatozoa.
50. 1. Birth control pills, injections, or patches prevent ovulation. 2. Intrauterine devices and
emergency contraceptives prevent fertilization and/or implantation. 3. Barrier methods
(female condom, tubal ligation) prevent contact between the spermatozoa and the ovum.
4. Spermicides kill spermatozoa.
