Egg Donation With Gestational Surrogacy In India
Oocyte donation (Egg Donation) combined with gestational surrogacy is one of the most effective treatments available to help infertile couples achieve pregnancy. The probability of a live birth depends greatly on the fertility potential of the oocyte donor and has been in the 50-80% range at IVF-ICSI CENTER.
This treatment is used if the intended mother is unable to conceive or carry a pregnancy in her uterus and cannot or should not for genetic reasons get pregnant with their own eggs. It allows a couple to have a child genetically linked to the intended father.
The most common reasons for surrogacy are the intended mother’s previous hysterectomy, congenital uterine malformations and medical conditions making being pregnant too risky for the intended mother. The most common reason for needing egg donation is age-related suboptimal oocyte quality.

Process of oocyte donation with gestational surrogacy:
The gestational surrogacy with oocyte donation procedure is similar to in vitro fertilization: after the egg donor’s ovaries have been stimulated, the eggs are aspirated, inseminated with sperm from the intended father, incubated and one or more of the resulting embryos are subsequently transferred into the surrogate’s uterus.
Below is an example of a gestational surrogacy with egg donation treatment sequence. Actual treatment is individualized.
All medications are given as pills, skin patches, vaginal capsules or tiny, shallow injections just under the skin. The surrogate also takes one intramuscular injection a day for four days. All stages of this treatment take place in our clinic.
Gestational surrogacy consists of the following steps:
1. Ovarian Stimulation
To maximize the probability of a live birth, the egg door takes FSH (follicle stimulating hormone) and LH (luteinizing hormone) to stimulate production of as many high quality eggs as possible (usually 6-14 eggs).
During the 7 to 12 day ovarian stimulation, two to four ultrasound examinations and blood estrogen determinations are used to follow the development of the eggs. When the eggs are ready for retrieval, your donor will take an injection of HCG (human chorionic gonadotropin) hormone. This hormone completes the maturation process of the eggs.
The ultrasound image below shows fully stimulated ovaries. Each of the grape-like follicles (0.5 to 1 inch in diameter) contains a microscopic egg.

2. Egg Retrieval
Thirty-six hours after the hCG injection, a non-surgical oocyte retrieval is done in our center. This is typically a 5 to 10 minute procedure.
Using ultrasound guidance, a thin aspirating needle is passed through the top of the vagina into the follicles. Only the tip of the aspirating needle enters the pelvic area. Since the ovaries are located just above the top of the vagina, the tip of the needle is passed into the follicles without penetrating the uterus, cervix or the Fallopian tubes.
The intended father collects a semen sample by masturbation either at home or at our office and the highest quality sperm are added to the eggs 6 hours after the egg retrieval.
If your infertility history suggests the possibility of a male factor significant enough to keep the eggs from being fertilized using regular laboratory methods, you will be scheduled for the ICSI procedure. ICSI or Intracytoplasmic Sperm Injection, is a micromanipulation technique in which a single sperm is inserted directly into an egg.
The next day, select embryologists will examine the eggs for signs of fertilization. A normally fertilized egg (zygote) will show two pronuclei representing the genetic material from the egg and sperm.
The following day, embryos reach 4 cells, the day after, 8 cells and by day 5 after egg retrieval, they should reach the blastocyst stage.
4. Embryo Transfer
One to five days after the egg retrieval, the resulting embryo(s) are transferred into the surrogate’s uterus by passing a thin embryo transfer catheter through the cervix to the top of the uterus.
Extra embryos that are not transferred at this time can be cryopreserved and stored in liquid nitrogen.
5. Establishment of Pregnancy
A blood pregnancy test is scheduled approximately two weeks after the embryo transfer. A fetal heartbeat ultrasound is done two weeks after a positive pregnancy test.
Estrogen and progesterone supplementation of the pregnancy continues for 6 to 8 weeks. By that time, the placenta produces enough of its own estrogen and progesterone so that the supplementation can stop.
This ultrasound picture shows a six week pregnancy. The pregnancy sac is approximately an inch in diameter. The baby inside the sac is about 0.5 inch long, yet it is possible to already distinguish the head and the “tail” portion of the baby’s body.
