Spermatogonia

Correct Answer: A

Rationale: The correct answer is A because spermatogonia are indeed germ cells that give rise to sperm cells through the process of spermatogenesis. They are diploid cells, not male gametes. Spermatogonia do not have flagella; instead, mature sperm cells have flagella for motility. So, the correct answer is A because spermatogonia are the precursor cells for sperm cells, they are diploid, and they do not have flagella.

Correct Answer: C

Rationale: Correct Answer: C - Ectopic pregnancy Rationale: 1. IUDs do not prevent ectopic pregnancies. 2. IUD insertion increases the risk of ectopic pregnancy. 3. Ectopic pregnancy is a serious complication of IUD use. Summary of other choices: A: Young age - Age alone is not a contraindication. B: Nulliparity - Being nulliparous is not a contraindication. D: Abnormal uterine bleeding - It is a relative, not absolute contraindication.

Correct Answer: A

Rationale: The correct answer is A: Bleeding. Assessing for abnormal bleeding is crucial in reproductive health as it can indicate various conditions such as hormonal imbalances, infections, or malignancies. Bleeding can provide important clues about the client's menstrual cycle, potential pregnancy complications, or underlying health issues. Pain (B) is important but may be more subjective and can be related to various factors beyond reproductive health. Sexual orientation (C) is not directly related to assessing reproductive health problems. Masses (D) can be important but may not be as common or specific as abnormal bleeding in reproductive health assessments.

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.

Correct Answer: B

Rationale: The correct answer is B because increasing ICSH (Luteinizing Hormone) inhibits testosterone production by exerting negative feedback on the testes. ICSH stimulates Leydig cells in the testes to produce testosterone. When testosterone levels rise, it signals the pituitary gland to decrease ICSH secretion, thus inhibiting further testosterone production. A: Increasing FSH (Follicle-Stimulating Hormone) does not inhibit testosterone production. C: Decreasing ICSH would lead to reduced stimulation of Leydig cells and lower testosterone production. D: Decreasing FSH would not directly inhibit testosterone production as FSH primarily stimulates sperm production in the testes.
