Medications used for IVF treatment primarily focus on Ovarian stimulation. Ovarian stimulation in IVF is required for a good number of infertile couples. Every medical procedure requires a support system to achieve a positive outcome. Thereby in IVF, ovulation stimulation serves as such a system. Both ovarian stimulation and ovulation induction may look like same but are different in the extent to which the ovaries get stimulated. In Ovulation induction(OI) one or two mature eggs are released whereas, in Superovulation or Controlled ovarian stimulation(COS), multiple eggs are released thus resulting in a high success rate for IVF.
