Egg retrieval: definition and meaning
Egg retrieval, also called egg collection, is a short procedure in IVF or egg freezing in which mature eggs are removed from the ovaries. Guided by a vaginal ultrasound, a doctor passes a thin needle through the vaginal wall into each follicle and gently suctions out the fluid and egg. It usually takes 15 to 30 minutes under sedation.
How egg retrieval fits into IVF
- Stimulation: about 8 to 14 days of hormone injections help several follicles grow.
- Trigger shot: an hCG or GnRH agonist injection finishes egg maturation.
- Retrieval: done about 34 to 36 hours after the trigger, just before eggs would be released.
- Next: eggs are fertilized in the lab or frozen. See IVF.
What recovery is like
Most people go home the same day. Cramping, bloating, spotting and tiredness for a few days are common, because the ovaries are enlarged. Rest, fluids and simple pain relief usually help. A period often comes about 10 to 14 days later if no embryo is transferred.
Call your clinic urgently for severe or worsening belly pain, fast weight gain (more than 1 kg or 2 lb a day), a very swollen belly, shortness of breath, peeing much less, heavy bleeding or fever. These can be signs of ovarian hyperstimulation syndrome (OHSS), bleeding or infection.
The emotional side
The number of eggs collected can feel like a verdict, and the days waiting for fertilization news are tense. Mood can also dip as hormone levels drop after retrieval. Many clinics offer counseling, and it is normal to need support. See also ovarian reserve and the IVF due date calculator.
Frequently asked questions
Does egg retrieval hurt?
You are usually sedated, so most people feel little during it. Afterward, cramps similar to strong period pain are common for a day or two.
How many eggs are usually retrieved?
It varies widely with age and ovarian reserve; around 8 to 15 is common in younger people. More is not always better, as quality matters too.
