Egg donation treatment and centre

Our guarantees of success:

Donors between 18 and 30 years old (the law allows donation up to the age of 35).

A minimum of 8 mature eggs.

Enough embryos for at least 2 transfers (one in fresh and the other with vitrified embryos.) Except in cases of severe male infertility.

No waiting list.

All phenotypes.

Fixed date for the transfer, allowing you to organise your trip at least one month in advance.

If you do not live in Spain...

You only need to visit to Ginemed once.

The pre-treatment tests can be sent by email, fax or brought to the free initial information consultation.

We evaluate your results and programme the treatment for the date of your choice.

The treatment controls can be done in your home country.

Treatment stages

Fase de programación

At Ginemed, we adapt perfectly to your needs

  • As soon as possible. We will start the ovarian stimulation with your next menstrual cycle.
  • On a specific date for the embryo transfer. This gives you time to organise your trip, reserve hotels and plan your days off work, etc...
Fase de preparación endometrial
Preparing the endometrium

We use oestrogens to prepare your endometrium to receive the embryos. The treatment begins with your menstruation and two ultrasounds are required. This stage takes around 12-14 days.

Fase de donación y muestra de semen
Donation and semen sample

The donor’s ovarian puncture takes place when the follicles have reached the correct size. On this day we also need the semen sample to fertilise the donor’s eggs.

Fase de laboratorio: fecundación y cultivo

Fertilisation is normally done using intra-cytoplasmic sperm injection (ICSI), which consists in introducing a spermatozoid into the egg using a micro needle.

Following the fertilisation of the eggs, the embryos remain in the laboratory for a few days until the embryologist determines when the best moment is to transfer. In some cases, to improve results, special laboratory techniques can be used.

Fase de transferencia embrionaria
Embryo transfer

This consists of placing the embryo into the uterus through a thin catheter introduced into the cervix. It is not painful and is normally carried out 2-6 days following the egg retrieval; usually on the third day. Spanish legislation allows up to three embryos to be transferred.

Fase de tratamiento postransferencia
Post-transfer treatment

Following the embryo transfer, we recommend that you rest for the remainder of the transfer day and only carry out relaxed activities the following day; later you can return to normal life. There are no problems with transport, including travelling by plane. We recommend avoiding strenuous activities and competitive sports for two weeks after the transfer. Normally, we prescribe a treatment of vaginal progesterone, beginning the day of the egg donation. We also recommend taking folic acid .

Fase de confirmación de embarazo
Confirmation of pregnancy

12 days after the embryo transfer, a blood analysis (B-HCG) is carried out to confirm the pregnancy. Do not suspend the medication without instruction from your gynaecologist regardless of the results.

Fase de ecografía

15 days after the B-HCG analysis, an ultrasound scan must be carried out to confirm the gestation (single or multiple) and to confirm the presence of a fetal heartbeat.

Egg donors: the success of our programme

Our egg donors are caring people; in Spain donation is always altruistic. The rigorous selection process involved in selecting our donors means that we have the highest results in egg donation.

To donate eggs, you should be between 18 and 30 years old (although the law does permit donation until the age of 35) and pass an exhaustive health examination. Although donation is anonymous, the large number of donors that we have allows us to select the donor that best matches your physical characteristics: race, skin tone, eye colour, hair colour, etc...

Embryo vitrification

Any viable pre-embryos, which have not been transferred, must be vitrified (Act 14/2006).

Vitrification consists of freezing the pre-embryos instantaneously; this prevents the formation of ice crystals and, as a result, the risk of damage to the cellular structures of the embryos when they are thawed practically disappears.

Thanks to the advanced vitrification techniques that Ginemed uses, the survival of the pre-embryos during the thawing, following vitrification, is practically 100%.

We are obtaining practically identical pregnancy rates in vitrified cycles as we are in cycles using fresh embryos.

Vitrificación de embriones


At Ginemed our results are around 60% (pregnancies confirmed by positive fetal heartbeat). The results do not depend on the age of the recipient, but they do vary depending upon the number of embryos transferred.
