IVF with your own eggs and sperm donation

DEFINITIONIn Vitro Fertilization with your own ovules and sperm donation is a laboratory technique consisting of fertilizing the eggs, previously extracted, with the sperm of an anonymous donor.


When is it IVF with your own eggs and sperm donation?

The IVF with your eggs and sperm donation is a laboratory technique of fertilizing the egg, previously extracted, with sperm from an anonymous donor. From a healthy donor, the sample presents optimal conditions regarding both quality and quantity of spermatozoa. Once fertilized, the egg turns into a pre-embryo and is transferred to the uterus so that it continues to grow there.

You will use this type of fertilization if you want to have a child alone, if your partner is a woman, or if, after several unsuccessful attempts at in vitro fertilization with your partner's sperm, there is the reason to believe that failure Is of male origin.

It is also used in cases of azoospermia (total absence of sperm in the sperm) or when the sperm has been used unsuccessfully.

More rarely, when a man has a chromosomal abnormality and, for ethical reasons, he does not plan to submit to a genetic diagnosis of pre-implantation (the study of chromosomal characteristics of the embryo before implantation in the 'uterus).

Phases of IVF with your own eggs and sperm donation

1. Control and stimulation of the ovaries

Ovaries are stimulated by administering hormones (follicle stimulating hormone FSH and, in some cases, LH luteinizing hormone), and the cycle is monitored with eggs until the number and size of the follicles are appropriate. It is at this point, thanks to the administration of another hormone that mimics the LH (or lute stimulon), the one that naturally induces ovulation, which causes the release of the ovule.

2. Doctors select the sperm and prepare the sample

The sperm sample comes from a donor who has undergone a complete medical examination (sperm analysis, blood and urine tests, general exploration, sexually transmitted diseases and psychological examination) to ensure the quality of his Spermatozoa and rule out any pathology. All donors are mature, sign a consent and commit to keeping their donation secret.

The sperm is frozen before use; It is only used for at least six months, once the incubation period for some sexually transmitted diseases has passed.

3. Egg mining and in vitro fertilization

The extraction of the ovules is done by aspiration and aspiration of the follicles. It is a process that requires sedation anesthesia. Once extracted, the eggs are kept for a few hours in a culture medium, while the sperm is prepared by isolating the moving spermatozoa.

If the technique chosen is ICSI (microinjection of a spermatozoon in each mature ovule), the eggs are "stripped." That is, the cell ring surrounding them is removed and then injected Spermatozoa in each of them.

In our center, and without contraindication, Doctors practice the ICSI in 99% of the cases. With classical IVFs, the spermatozoa (50 to 100 000) are immersed in the culture medium where the eggs are found. The next day, Doctors verify how many of these have been fertilized.

Obviously, the more eggs and the better the quality of the sperm, the greater the chances of obtaining embryos. However, this technique has a disadvantage: fertilization rates are lower because the spermatozoa are not introduced directly into the ovum.

4. Transfer

The day after the extraction and ICSI of the ova, it is known how many of them have been fertilized. The next two to three days, these fertilized eggs turn into pre-embryos ready to be transferred into the uterus.

On the day of the transfer, the pre-embryos which have the best development characteristics are selected. The law allows us to transfer up to 3 embryos, but the most usual average number is 2.

The pre-embryos, introduced into a very fine catheter, are led by the gynecologist to the bottom of the uterus. Anesthesia is not necessary. On the transferred pre-embryos, usually only one implant is implanted; It must be known that it may happen that many do so, giving rise to multiple pregnancies.

5. Cryopreservation

The pre-embryos that have not been transferred are frozen in liquid nitrogen (this cryopreservation is known as vitrification), after which, suitably labeled, they are stored in the embryo library. They can be used in subsequent cycles if the first attempt is not successful. Obviously, the preparation of the uterus for a transfer of frozen embryos is much simpler since the stimulation, and the extraction of eggs are not necessary.
