Oocyte Donation is used for women who cannot produce their own eggs or produce poor quality eggs incapable of forming a viable embryo.
This process involves the fertilization of the eggs with sperm from the patient's partner. The embryos develop in the laboratory and are transferred into the woman's uterus.
It is applied in those cases where the woman that wants to achieve pregnancy presents absence of oocytes or major alterations in oocytes, making natural conception difficult.
It is also applied in the case of women who have had their ovaries removed after being treated for cancer or other serious disease, and those women who are potential transmitters of hereditary disorders.
Oocytes are obtained from healthy women, aged less than 35 years. Donated oocytes come from voluntary women: In some cases, they donate their spare eggs after undergoing In Vitro Fertilization procedures and in some others, women agree to undergo the treatment with the intention of donating their eggs to who may need them. Oocyte Donation is anonymous.
Sublimis considers that donation should be anonymous, respecting both the donor and recipient's physical characteristics. This means the recipient is provided with oocytes from a donor whose physical characteristics most closely resemble those of her (skin color, eye color, height, body build, etc.).
Likewise, blood group is matched as closely as possible to the characteristics of the intended recipient couple and we take all reasonable precautions against infectious diseases that could be transmitted.
Sublimis requires women who desire to receive donated oocytes to bring volunteers, not necessarily meaning the commitment of a direct exchange.
This donation requires mutual consent by both members of the couple, apart from communication and counseling that could guarantee the emotional stability of every person involved.
The donor is required to undergo routine tests -pap smear and colposcopy-, blood group tests, tests to rule out HIV (AIDS) types I and II, B and C Hepatitis, Syphilis, and all other tests that could prevent the transmission of infectious or genetic diseases.
Once the donor has been accepted as such, the couple has to sign an informed consent agreement and once they have been assigned a recipient, we proceed to stimulate ovulation in order to obtain oocytes that will be fertilized with IVF or ICSI techniques.
The recipient must be a woman -aged less than 45 years- previously diagnosed as infertile or subfertile. Both the recipient and he partner need to sign an informed consent and agree to obtain professional counseling that could guarantee the possibility of emotionally embracing this experience.
From this moment, the woman will be scheduled in order to bring the hormonal state of her organism to the exact levels to be able to receive the embryos that will be conceived in our laboratory.
During this time, hormone tests and ultrasound examinations will be done in order to assure her capacity of receiving embryos. It will be significant to control the state of the endometrial mucosa since, as previously mentioned, it will be very important for the capacity of embryo implantation.
The recipient's partner must also undergo the necessary tests to guarantee his sperm capacity.
At present, the pregnancy rate with this procedure is of approximately 50% per cycle.
Sublimis considers gamete donation an advanced and efficient procedure if performed under the appropriate emotional and security conditions. This implies that both parties should be fully informed so as to make a responsible decision, counting with emotional and psychological support as well, in an attempt to make this a positive life experience.
By means of this technique we are offering the chance of pregnancy to many couples whom adoption would remain otherwise the only option.
We wish couples could pursue this treatment through dialogue and consent or to give up their desire to have children and look for other alternatives, but only after having known, evaluated and decided among the range of possibilities modern Reproductive Medicine offers.
