Provera (medroxyprogesterone acetate), a synthetic form of progesterone, is used in IVF (In Vitro Fertilization) to regulate menstrual cycles, particularly for women who ovulate irregularly or not at all.
Here's a breakdown of why Provera is beneficial in the IVF process:
-
Regulating the Menstrual Cycle: Provera helps to induce a predictable menstrual bleed. This is crucial because IVF cycles require precise timing for the administration of fertility medications. By triggering a withdrawal bleed after a course of Provera, the start of the IVF cycle can be controlled.
-
Preventing Ovarian Cysts: While not its primary purpose in IVF, Provera, similar to oral contraceptives, can help prevent the formation of ovarian cysts that might develop during the stimulation phase involving GnRH analogs.
-
For Irregular or Absent Ovulation: Provera is often prescribed for individuals who don't ovulate regularly or at all (anovulation). By inducing a period, it creates a clean slate, allowing fertility specialists to begin ovarian stimulation with other medications in a controlled manner.
In summary, Provera plays a vital role in synchronizing the menstrual cycle and preparing the body for the subsequent stages of IVF treatment, ensuring a more predictable and controlled process.
