How Long After a HCG Shot Should Insemination Occur?

Early to Mid-Ovulation

Insemination procedures are typically done approximately 24 to 36 hours post hCG injection. This is most often the case if only one insemination procedure is scheduled for the patient. Occasionally it can be done as early as 24 hours after the hCG injection is given, though this is not as common.

Late Ovulation

Some clinics report having better results doing the insemination procedure in patients 40 to 42 hours post-hCG injection.

Bottom Line

Ovulation typically occurs between 36 and 40 hours post-hCG injection. Because an egg is only viable for 24 hours after it is released from the follicle, it is preferable for insemination to happen sooner after the hCG injection is given. While some doctors report success doing the insemination at 40 to 42 hours after the hCG injection, it is much more common and widely accepted that it should occur 24 to 36 hours post-hCG injection.
