What is the role of testosterone in women during pregnancy?

1. Stimulates milk production

2. Increases estrogen production

3. Maintains fertility

4. Contributes to follicular development

The correct answer is: Maintains fertility

Testosterone plays a significant role during pregnancy, particularly in the maintenance of fertility. In women, testosterone is produced in small amounts by the ovaries and adrenal glands, and it contributes to various physiological functions. During pregnancy, testosterone helps to regulate the production of other hormones essential for maintaining the pregnancy. One of the key aspects of fertility is the presence of appropriate hormone levels to support ovulation and the early development of the embryo. Testosterone is involved in this hormonal balance, supporting the ovarian function necessary for conception and sustaining early pregnancy. This is important as an adequate hormonal environment is crucial for successful implantation and maintenance of the pregnancy. Although testosterone has a minor role compared to hormones like estrogen and progesterone in pregnancy, its function in maintaining fertility through the regulation of hormonal balance is critical. Other options provided focus on functions such as milk production or follicular development, which are more closely associated with other hormones rather than testosterone's primary responsibilities during pregnancy.
