Question: how long does it take to ovulate after taking ovidrel?
Answer: The patient will receive just one injection of a hormone called human chorionic gonadotropin (Ovidrel) that will cause the egg(s) to be released about 38-40 hours later and to mature the egg(s) for fertilization. 36 hours after the Ovidrel injection, she is ready for the intrauterine insemination.
