What is the purpose of the bulbourethral glands in the male reproductive system?

Correct Answer: D

Rationale: The purpose of the bulbourethral glands is to lubricate the urethra before ejaculation. This lubrication helps to neutralize any acidic urine remnants in the urethra, providing a more suitable environment for sperm to pass through. The other choices are incorrect because: A: Sperm is produced in the testes, not the bulbourethral glands. B: Testosterone is mainly produced in the testes and adrenal glands. C: Semen is produced by the seminal vesicles, prostate gland, and sperm from the testes.

Correct Answer: A

Rationale: The correct answer is A: Ovary. The ovary is the primary organ responsible for producing estrogen in the female reproductive system. Estrogen is mainly produced by the ovarian follicles. It plays a crucial role in regulating the menstrual cycle, maintaining bone density, and promoting the development of female secondary sexual characteristics. The other choices, B: Uterus, C: Fallopian tube, and D: Cervix, do not produce estrogen. The uterus is responsible for implantation and gestation of a fertilized egg, the fallopian tube is where fertilization occurs, and the cervix is the lower part of the uterus that connects to the vagina.
