IVF Procedure – Step Two: Egg Harvesting

The in vitro fertilization procedure involves four primary stages - ovulation induction, egg harvesting, insemination and fertilization, and embryo transfer. IVF usually begins on the third day of the patient's menstrual cycle. Once the embryo transfer procedure has been performed and the IVF process is complete, the chance of a successful pregnancy ranges from 20 to 50 percent, according to some clinics.

Egg Harvesting

In this stage of the in vitro fertilization process, the ova must be harvested before ovulation occurs, or else they will be lost in the female reproductive tract. Ultrasound scanning can be used to monitor follicle development. Blood samples can also be taken to measure estrogen levels, which should rise as the follicles mature. About a day and a half before ovulation, an hCG injection is administered. This should cause ovulation to occur approximately 36 hours later. In some cases, a spontaneously occurring luteinizing hormone (LH) surge can trigger premature ovulation.

Ultrasound-Guided Aspiration

The most common technique used for egg harvesting is called ultrasound-guided aspiration. This method involves inserting an ultrasound probe into the vagina. The probe emits sound waves, which are used to form an image of the reproductive organs. The fertility specialist guides a tiny needle through the vagina and into a follicle, where gentle suction draws the ovum into the needle. The aspiration procedure can also be performed through the abdominal wall or bladder. In some cases, a laparoscopy may be needed for successful egg harvesting.
