Final answer:
The primary drug of choice for treating infertility due to Polycystic Ovarian Syndrome is Clomiphene, an ovulation induction agent. Metformin may be used as an adjunct treatment, and in more resistant cases, gonadotropins or assisted reproductive technology may be considered.
Step-by-step explanation:
The drug of choice for treating infertility related to Polycystic Ovarian Syndrome (PCOS) is Clomiphene. Clomiphene is an ovulation induction agent that acts by stimulating the pituitary gland to release hormones needed to induce ovulation. This medication is commonly used in cases where women with PCOS are unable to ovulate naturally.
While metformin can be used to treat several symptoms of PCOS, including improving insulin functioning and lowering testosterone levels, it is not the primary choice for treating infertility-related PCOS. Instead, it may be prescribed as an adjunct treatment. In cases where Clomiphene is not effective, other fertility medications, such as gonadotropins, might be considered. The use of gonadotropins involves a higher risk of multiple pregnancies and associated complications. Assisted reproductive technology (ART) is another option if medication alone does not result in successful conception. ART encompasses a variety of procedures that manipulate eggs and sperm in a laboratory setting to improve the chances of fertilization and embryo development.
