IVF involves administering supraphysiological FSH and LH to mature multiple eggs for fertilization.

“IVF involves administering supra-- meaning greater than normal-- supraphysiological levels of follicle-stimulating hormone and luteinizing hormone during the follicular phase of a woman's cycle. What that causes is the maturation of not just one egg that would be ovulated but multiple follicles and eggs. And then ovulation itself is suppressed also through the administration of exogenous hormones. And then, under ultrasound guidance, an OB/GYN goes in and collects the mature eggs and follicles, puts them in a dish, and then sperm are delivered to that dish, and those could either be sperm that were frozen previously, or more typically or ideally, it would be live sperm collected that day that are washed through a very straightforward procedure.”
