The endometrial thickness is greatest during the:
- A. Secretory phase
- B. Menstrual phase
- C. Proliferative phase
- D. Late follicular phase
Correct Answer: A
Rationale: The correct answer is A: Secretory phase. During the secretory phase of the menstrual cycle, the endometrial thickness is greatest due to increased progesterone levels, leading to thickening of the endometrium in preparation for potential implantation of a fertilized egg. This phase occurs after ovulation and is characterized by glandular secretions and increased vascularity to support a potential pregnancy.
Summary:
- Menstrual phase (B) is incorrect as it is characterized by shedding of the endometrial lining.
- Proliferative phase (C) is incorrect as it involves endometrial thickening but not to the extent seen in the secretory phase.
- Late follicular phase (D) is incorrect as it precedes ovulation and is primarily characterized by follicular development rather than significant endometrial thickening.

Ova and sperm are also known as which of the following?
- A. Gonads
- B. Gametes
- C. Stem cells

Correct Answer: B
Rationale: The correct answer is B: Gametes. Ova and sperm are reproductive cells involved in sexual reproduction. Gametes are specialized cells that combine during fertilization to form a new organism. They are distinct from gonads (A), which are the organs that produce gametes. Stem cells (C) are undifferentiated cells that can develop into various cell types, not specific to ova and sperm. Hormones (D) are chemical messengers produced by endocrine glands, not directly related to ova and sperm production.
