IVF Egg Donation in Mexico

Difficulties with ovulation are the most frequent cause of infertility in women. IVF clinics in Mexico pride themselves as pioneers in the science of reproductive treatments. There are many reasons for problems with egg production and women who experience premature menopause. Women who suffer from ovarian failure or are having unrelated treatment that may affect fertility can use donated eggs to conceive through IVF methods. Donated eggs are fertilized with sperm through the process of ICSI, and then they get transplanted into the recipient’s uterus using IVF. Egg donors can be chosen by the recipient or by the clinic. The procedure of egg donation involves a thorough screening of egg donors to check for genetic and mental problems. Donors selected by the clinic are generally between the ages of 20-30, and ideally have their own children. Donor egg recipients will be matched to a donor who shares similar physical characteristics such as skin color, eye color and other attributes. Many doctors attribute their success with IVF egg donation treatment is the cutting edge fertility technology of Mexico clinics and healthcare system.

Treatment, Step by Step

1. The donor egg recipient couple is screened for infectious diseases like Hepatitis B & C, HIV and for sexually transmitted disease like syphilis, gonorrhoea and chlamydia.

2. The donor is chosen. The donor can be someone the recipient knows, such a family member or friend, or she can be anonymous, in which case her physical characteristics are matched to the recipient by the clinic.

3. To ensure successful IVF using egg donation, the menstrual cycles of the donor and recipient will be synchronized. Specialists use fertility medication and oral contraceptives to synchronize the cycles and ensure egg collection and embryo transfer procedures occur on the optimum day for conception.

4. Fertility medication given to the recipient induces ovulation to encourage the uterus to thicken in preparation for the embryo transfer.

5. The uterus lining is thickened using hormone supplements to replicate a normal menstrual cycle. Hormone supplements are taken for about 7-10 days before embryo transfer and the uterus lining and hormone levels are monitored using blood tests and vaginal ultrasounds.

6. Once the recipient’s uterus lining is in ideal condition for implantation, the donor’s eggs will be retrieved using egg collection methods. Sperm will be collected at the same time or cryopreserved sperm will be thawed for use in the in vitro fertilization.

7. Eggs are collected from the egg donor. Using a thin needle, individual eggs are collected by suction from the ovarian follicles of the donor. The process takes half an hour and the donor will experience slight cramping afterwards.

8. The recipient will continue taking oral estrogen and will also take progesterone vaginal suppositories, in order to complete the thickening of the uterus

9. ICSI is used to fertilize the donated eggs by injecting sperm into the centre of the egg. The fertilization process begins as the cells start to divide and multiply.

10. The timing for embryo transfer will be determined by the fertility doctor and the fertility clinics procedure. Embryos can be transferred 1-5 days after fertilization. Many doctors now implant the embryo into the recipient’s uterus on day 5, during the blastocyst stage of fertilization to ensure the embryo is mature and will successfully implant.

The donor will be asked to drink one liter of water one hour before the transfer to expand the bladder so that the uterus moves from an anteflexed position. Using a catheter, the embryos are placed into the uterus and the recipient is required to rest for a couple of hours. The number of embryos transferred per IVF cycle depends on the specialists recommendations for the individual recipient.

Extra Embryos
Inducing ovulation often produces more eggs than are needed for one IVF cycle. All eggs that fertilize can be frozen and stored for future use with cryopreservation.

Success Rates
The success rate of IVF with egg donation varies depending upon age of eggs, retrieval process, quality of semen, and the overall health of the women involved. In most cases, younger eggs are selected to increase the probability of success. About 50% of women undergoing egg donor IVF will get pregnant.

The cost of IVF egg donation in Mexico is significantly lower than the US and Europe because of Mexico’s efficient and cost-effective healthcare system which allows millions of couples to visit each year for IVF treatment.
