1. Bromocriptine reduces elevated prolactin levels, which can normalize menstrual cycles and increase ovulation, thus enhancing fertility.

2. By lowering prolactin, bromocriptine helps restore ovarian function and regular ovulatory cycles, leading to improved conception rates.

3. Bromocriptine therapy corrects prolactin-induced hypogonadism, allowing for resumption of normal ovarian function and fertility in women.

4. Bromocriptine usage directly decreases high prolactin, which is often responsible for anovulation and infertility, thereby improving pregnancy chances.
