Finasteride works by inhibiting the enzyme 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). High levels of DHT are crucial for male genital development; if a female fetus is exposed to finasteride, it can lead to improper development of the genitalia and other congenital malformations.

This teratogenic risk necessitates that women who are pregnant or may become pregnant avoid the medication. Due to these concerns, it is classified as a category X medication by the FDA, meaning that it is contraindicated during pregnancy due to the demonstrated risk of fetal harm.

Finasteride does not lead to increased fertility, and asserting that it has no effect on pregnancy or that it is safe for use without restrictions ignores the serious hazards associated with exposure during pregnancy. Therefore, the correct choice highlights the critical nature of understanding the risks finasteride presents to pregnant women or those who
