What is Ovidrel, and what does it do in fertility treatment?
Ovidrel is a medicine used to help trigger ovulation as part of fertility care. It contains choriogonadotropin alfa, a lab-made version of human chorionic gonadotropin (hCG). After it is given, the medication starts the body’s “LH surge” process that leads to release of an egg from the ovary, or supports the timing needed for fertility procedures [1].
How does Ovidrel work (mechanism)?
Ovidrel provides an hCG-like signal to the ovaries. This helps initiate the final steps of follicle maturation and the release of the egg. In reproductive medicine, clinicians use this timing effect to better coordinate ovulation with intercourse or with procedures such as intrauterine insemination (IUI) [1].
How is Ovidrel typically used—triggering intercourse or procedures?
In fertility protocols, Ovidrel is usually used to schedule ovulation so that eggs are available at the right time. That timing can be used for:
- Timed intercourse after a trigger injection
- IUI cycles where the procedure is scheduled after the trigger
- Certain assisted reproduction steps where egg timing matters [1]
What does Ovidrel not do?
Ovidrel is not the hormone that stimulates follicle growth by itself. It acts as the trigger for the final ovulation event after follicles have been prepared by other medications (commonly FSH or similar agents, depending on the regimen) [1].
What patients are often told to watch for
Because Ovidrel supports ovulation, patients may be instructed to monitor for side effects related to ovarian stimulation and ovulation timing. One key safety concern clinicians watch for in fertility cycles is ovarian hyperstimulation syndrome (OHSS), which can occur when ovaries respond strongly to stimulation. If you’re using Ovidrel as part of a cycle, your care team’s guidance on symptoms to report is important [1].
