The correct Answer is:
To solve the question regarding the effects of disrupted progesterone receptors, we need to analyze each option based on the role of progesterone in the body. ### Step-by-Step Solution: 1. **Understanding Progesterone's Role**: - Progesterone is a crucial hormone involved in the menstrual cycle and pregnancy. It is primarily responsible for preparing the endometrium (the lining of the uterus) for potential implantation of an embryo and maintaining pregnancy. 2. **Analyzing Option (a)**: - **Statement**: Secondary sexual characters would not be maintained. - **Analysis**: Progesterone does not directly maintain secondary sexual characteristics; these are primarily influenced by estrogen. Therefore, this option is **incorrect**. 3. **Analyzing Option (b)**: - **Statement**: Pituitary gonadotropins will not be secreted. - **Analysis**: The secretion of pituitary gonadotropins (LH and FSH) is regulated by the hypothalamus and is not directly dependent on progesterone receptors. Thus, this option is also **incorrect**. 4. **Analyzing Option (c)**: - **Statement**: The uterus will not be able to support pregnancy. - **Analysis**: This statement is **correct**. If progesterone receptors are disrupted, the uterus cannot respond to progesterone, which is essential for maintaining the uterine environment suitable for pregnancy. Without this response, pregnancy cannot be supported. 5. **Analyzing Option (d)**: - **Statement**: The uterine endometrium will not begin to proliferate. - **Analysis**: While progesterone does play a role in the proliferation of the endometrial lining, it is not the only hormone involved. Estrogen also contributes to this process. Therefore, this option is **incorrect**. ### Conclusion: The correct answer is **(c) the uterus will not be able to support pregnancy**.
