- A. producing
- B. estrogen functions and are called ________.
- C. progesterone
- D. testes
Correct Answer: D
Rationale: Step-by-step rationale for why the correct answer is D:
1. Testes are the male gonads responsible for producing sperm.
2. The testes function as the primary reproductive organ in males.
3. Sperm production occurs in the seminiferous tubules within the testes.
4. The testes also produce testosterone, the primary male sex hormone.
Summary of why other choices are incorrect:
A: Producing - While testes do produce sperm, this choice lacks specificity regarding the male gonads.
B: Estrogen functions and are called ________ - Estrogen is a female sex hormone, not produced by male gonads.
C: Progesterone - Progesterone is a female sex hormone produced mainly by the ovaries, not by male gonads.

What is line “C” pointing to?
- A. Bladder
- B. Fimbriae
- C. Ovary
- D. Uterus
Correct Answer: C
Rationale: The correct answer is C: Ovary. Line "C" is pointing to the ovary because it is the reproductive organ responsible for producing eggs and hormones in females. The ovary is located near the fimbriae and not the bladder or uterus. The fimbriae are finger-like projections near the ovary that help guide the released egg into the fallopian tube. The bladder is an organ unrelated to reproduction, and the uterus is a separate reproductive organ responsible for housing a developing fetus. Therefore, the correct choice is the ovary as it aligns with the function and location indicated by the diagram.
Frank is a 24 year old man who presents with multiple vesicles and burning erosions on the shaft of his penis and some tender inguinal adenopathy. Which of the following is most likely?
- A. Primary syphilis
- B. Herpes simplex
- C. Chancroid
- D. Gonorrhea
Correct Answer: B
Rationale: The correct answer is B: Herpes simplex. This is because the presentation of multiple vesicles, burning erosions on the penis shaft, and inguinal adenopathy is classic for genital herpes. Primary syphilis (A) presents with a painless chancre, chancroid (C) with painful ulcers, and gonorrhea (D) with urethral discharge or dysuria. Genital herpes is a viral infection caused by HSV-1 or HSV-2 and typically presents with vesicles, erosions, and adenopathy in the affected area.
Fertilization occurs in the:
- A. uterus
- B. fallopian tubes
- C. labia
- D. vagina
Correct Answer: B
Rationale: The correct answer is B: fallopian tubes. Fertilization occurs in the fallopian tubes where the sperm meets the egg. The fallopian tubes are where the egg is released from the ovary and where fertilization takes place. The uterus (choice A) is where the fertilized egg implants and develops into a fetus. The labia (choice C) are external genital structures and do not play a role in fertilization. The vagina (choice D) is the birth canal and does not directly participate in fertilization. Therefore, the fallopian tubes are the correct choice for the site of fertilization in the female reproductive system.
The superior region of the vagina is the _____.
- A. vaginal orifice
- B. cervix
- C. hymen
- D. vaginal rugae
Correct Answer: B
Rationale: The correct answer is B: cervix. The cervix is the lower portion of the uterus that protrudes into the vaginal canal. It is located at the superior region of the vagina. The vaginal orifice (A) refers to the opening of the vagina, not the superior region. The hymen (C) is a thin membrane that partially covers the vaginal opening and is not related to the superior region. Vaginal rugae (D) are the ridges or folds in the vaginal wall that allow for expansion, which are not specific to the superior region.
The ejaculatory duct is the union of the vas deferens and _____.
- A. seminal vesicle
- B. prostate
- C. ampulla
- D. urethra
Correct Answer: A
Rationale: The correct answer is A: seminal vesicle. The ejaculatory duct is formed by the union of the vas deferens and the seminal vesicle. The seminal vesicle contributes seminal fluid that mixes with sperm from the vas deferens to form semen. The prostate gland surrounds the ejaculatory duct but does not directly join it. The ampulla is an enlarged portion of the vas deferens but does not directly connect to the ejaculatory duct. The urethra is the tube that carries urine and semen out of the body but is not part of the ejaculatory duct. Therefore, the correct answer is A because the seminal vesicle directly joins with the vas deferens to form the ejaculatory duct.
