Embryo Donation

What is the meaning of embryo donation?

Embryo donation is a known method that allows embryos to be transferred to infertile patients, helping them achieve pregnancy. In other cases, the procedure helped researchers advance in the study of reproductive medicine. Embryo donation is a two-way process. One, it involves those embryos produced by spouses receiving fertility treatment. Second, they were primarily designed from donated sperm and donated eggs.

In other words, embryo donation is a type of third-party procreation. Here, discarded embryos from an individual's or couple's in-vitro fertilization (IVF) procedure are given to another individual or couple.

What is the process of embryo donation?

Doctors use IVF techniques (donor sperm and donor eggs) to produce an embryo and fill the receiving woman's uterus with the fertilized embryo. The recipient then receives care throughout her pregnancy and delivery. Once delivered, the mother subsequently regards the infant as her own. It is the same as the concept that underlies sperm or egg donation. Embryo donation is frequently an anonymous approach. This privacy is maintained to protect the confidentiality of all persons involved in the process. 

When is embryo donation a feasible option?

Where pregnancy using one's gametes is not an option, adopting embryos is a reproductive alternative. Typically, the following scenarios are prevalent:

  • Infertile women with no male companion.
  • When both partners in the relationship experience infertility issues. This problem can either occur due to poor egg or seminal quality.
  • Failures in earlier IVF cycles using their eggs.
  • Recurring miscarriages
  • Possible genetic disease transmission

What are the benefits of embryo donation? 

  • Low in cost 

The procedure does not call for controlled ovarian stimulation procedures or the identification of compatible female donors. Moreover, the IVF lab defrosts, monitors, and transfers the remaining embryo. As a result, the patient's expense is also significantly reduced.

  • Easy endometrial preparations and no waiting list

Usually, there isn't a waiting list for the recipient. Experts only need to prepare the embryos for endometrial implantation and cryopreserve them. Nevertheless, treatment for endometrial preparation is easy and painless.

  • High rates of success

Embryo survival rates are high. The success rates are nearly 100%, thanks to advances in cryopreservation methods known as vitrification. Moreover, gestation rates are extremely high when a single blastocyst is transplanted (SBT).

  • Value added to life

The emotional impact of assisting other couples in becoming pregnant is priceless. The idea behind the process is that the embryos (which would have otherwise stayed cryopreserved) now have a valuable home.

Things to know about embryo donation

Here are a few things to know about the procedure:

  • The medical staff works to match the donor's and recipient's physical traits in both gametes (eggs and sperm) and embryo donation cases (e.g., blood type). 
  • For embryo adoption treatment, having a low body mass index is not necessary. It is advantageous to have a normal BMI, but it is not required to be able to accept donated embryos.
  • Unbelievably, even though an embryo is partially "foreign," a woman's uterus does not reject it. Because the sperm of the man is foreign. The fact that the uterus accepts an embryo from a double gift of sperm and egg is even more fascinating.

1. How effective is embryo donation?

Donating embryos is a new field. The quality of the embryo, the age of the egg donor, the number of embryos transferred, and the embryo's developmental stage when frozen all affect success rates as expressed in live births per embryo transfer.

2. How are possible donors for embryos screened?

Most often, those who donate embryos have experienced in-vitro fertilization. The doctors will do several tests on a donor at a clinic as part of their care. Extensive medical and genetic histories will also be part of the exams.

3. Is adopting embryos throughout the normal cycle possible?

Although it is uncommon, it is possible. Typically, the woman undergoes hormonal therapy to encourage endometrial growth, raising the possibility of implantation and subsequent pregnancy.

4. Does the embryo donor have parental responsibility over the kids conceived from such embryos?

No. Donors must sign a form of informed consent authorizing the use of their body parts for the donation of embryos. They renounce all ownership of the embryos as well as any offspring that might be born as a result of the donation. This renouncement is all a part of the consent procedure.

5. Which laboratory tests are necessary for recipients of embryos?

The laboratory tests consist of the following: 1. Screen for antibodies, the Rh factor, and blood type. 2. Before becoming pregnant, immunity to varicella and rubella should be verified. 3. Hepatitis B surface antigen, hepatitis C antibody, and other serologic tests. 4. Examinations for types I and II of the human T-cell lymphotropic virus\\ Depending on the doctor and hospital, there might also be other tests a recipient needs to undergo before embryo donation.
