Egg Donation

Egg donation is an assisted reproduction technique that uses anonymous donor eggs to create maximum quality embryos. It can be done with donor sperm or sperm from your partner.

Treatment phases

1. Selecting a Donor

The donor is anonymous and selected based on the recipient’s physical traits and blood type. If you would like, the donor can also be selected based on genetics (genetic matching).

2. Preparing the endometrium

The recipient prepares her uterus using oestrogen (in the form of pills or patches) and the process is monitored by If the donated eggs are to be fertilized with your partner’s sperm, he must provide a sperm sample to analyse the sperm’s viability.

3. Follicular Puncture and Fertilisation

Follicular Puncture (donor). After 10 -12 days of ovary stimulation, the donor’s eggs are retrieved via follicular puncture.

ICSI (Intracytoplasmic sperm injection). The highest-quality spermatozoa (from partner or donor) are selected from a sperm sample (fresh or frozen) and microinjected into each egg.

4. Blastocyst Transfer

The embryo (blastocyst) is transferred to the uterus under ultrasound guidance. We recommend that the patient rest for 20 minutes after the procedure.

How are donors selected?

Donors are anonymous women, under 35, without health problems and without a family history of any health problems, who have undergone numerous medical, psychological, and genetic examinations.

The ideal donor is selected based on the recipient’s physical traits and blood type.

If you would like, donors can be selected based on genetic compatibility (genetics matching).

Vitrified Eggs

As well as being able to retrieve fresh eggs (after the donor’s follicular puncture), the treatment can also be done with vitrified (frozen) eggs from our own egg bank.

The pregnancy rates are the same, but the main difference is that less time is needed to prepare the endometrium (starting directly with oestrogens in conjunction with menstruation) since the donor and the recipient don’t need to synchronise cycles. In addition, you can decide on the exact day for the transfer since we thaw the eggs based on the chosen date.

Real testimonials
