Egg Collection

The egg collection procedure, which involves retrieving or aspirating the eggs from the ovary, fertilizing them in the laboratory, and transferring the embryos back into the uterus a few days later. It is a minor procedure performed under sedation or general anaesthesia depending on the patient’s condition.

How does egg collection work?

  • The egg collection is performed in our specialized IVF Operating Theatre (OT) via transvaginal ultrasound (similar to the ultrasound used for monitoring of follicles during stimulation).
  • Once the ovary is visualized by ultrasound, a very fine needle is passed through the vaginal wall into the ovary to harvest the eggs. The eggs which are now in a test tube are handed over to the embryologist for processing.
  • The embryologist examines the follicular fluid, identifies the egg, and then transfers each egg to a special culture media.
  • In order to ensure minimal exposure to the external environment our laboratory is located next to the IVF OT. The procedure takes about 15 minutes to complete and refreshments will be served once you are fully awake. You will be discharged about an hour later.

Body Mass Index calculator

Being overweight or underweight can reduce fertility, so it is important to keep your body weight within the normal healthy range.

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

Being underweight

If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
