Controlled Ovarian Hyperstimulation (COH)
- The patient is treated with a medication to enable her to release several eggs at the time of ovulation. Increasing the number of eggs the women releases may increase the probability of conception.
- This type of therapy is generally used for couples who have unexplained infertility, have mild male factor infertility, or have failed less aggressive treatment strategies.
- COH is often coupled with intrauterine insemination (IUI).
- Northwestern Medicine Fertility and Reproductive Medicine offers COH with oral medications (e.g., Clomid or Letrozole) or injectable medications (e.g., Bravelle, Follistim, or GonalF).
