Does fertilization occur immediately after egg release?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

Will fertilization occur immediately after an egg is released? And will the ovulation test show positive regardless of fertilization has occurred immediately? I had sex three days ago but the ovulation test still showed positive today. Please suggest.

Hi,

Welcome to icliniq.com.

Ovulation test is not confirmatory for ovulation. It means LH (luteinizing hormones) hormones increased during the menstrual cycle. Fertilization can happen within 24 hours after ovulation. Once LH surge happens ovulation actually occurs after 36 hours of LH surge. Ovulation test comes positive when LH surge happens. So you should have sex after two or three days of positive ovulation test. It is the most likely time of ovulation. But it is not confirmatory. Ovulation does not always happens after LH surge. Ovulation test does not have a relation with fertilization. Fertilization may or may not occurs even after ovulation.

Patient's Query

Thank you doctor,

So, is it better to try again after the ovulation test comes back positive? Or is there a chance I would be able to still get pregnant since I had sex three days ago?

Hi,

Welcome back to icliniq.com.

Try again is the better option. Sperm can fertilize for 72 hours after vaginal ejaculation. But for a better chance, it is always a good time to have sex after two days of positive ovulation test.
