Ovitrelle is a hormone called chorionic gonadotropin. It is administered to induce ovulation in those women who do not ovulate spontaneously or after ovarian stimulation as part of an assisted reproduction treatment.
Depending on the bioavailability of the drug, its half-life is 30 hours, after which most of it will be eliminated from the body. However, there may be interference in blood and urine tests up to 10 days after administration, which may lead to false-positive pregnancy tests. It is important that patients are warned to always take a pregnancy test at least 11 days after Ovitrelle has been administered.
