In Vitro Fertilisation Clinic Jerez

In Vitro Fertilisation (IVF) is an assisted reproduction treatment whose aim is to facilitate the union of the egg and sperm. This is done in the laboratory to obtain embryos. These embryos are then introduced into the woman’s uterus through embryo transfer so that they can continue their development and become pregnant.

In Vitro Fertilisation can be carried out by means of two different procedures:

  • Conventional in vitro fertilisation (IVF). The egg and sperm unite spontaneously in the laboratory.
  • Sperm Microinjection (ICSI). Fertilisation is carried out by injecting one sperm into each egg. The embryologist selects the sperm according to their motility and morphology to optimise the probability of fertilisation and good embryo development.


  • Tubal obstruction or tubal problems. Absence of tubes or hydrosalpinx.
  • Moderate or severe endometriosis.
  • Voluntary sterility due to tubal ligation or vasectomy.
  • Repeated insemination failure.
  • Low ovarian reserve.
  • Couples in which there is a moderate or severe male factor (significant alteration in the number, mobility or morphology of spermatozoa).
  • Couples in which no spermatozoa are found in the ejaculate and a testicular biopsy is required.
  • Risk of transmission of genetic or chromosomal disease to descendents detectable with current genetic diagnosis techniques.

In vitro fertilisation procedure

The aim of ovarian stimulation for in vitro fertilisation is to achieve controlled multiple ovulation. This requires hormonal treatment with medication. We need to obtain more than one egg in order to be able to work and have an acceptable number of embryos.

This procedure usually lasts between 10 and 12 days depending on the woman’s response. It is monitored by ultrasound and, if necessary, by hormonal determinations.

Once an adequate response to stimulation has been verified and when the follicles containing the eggs within the ovary have reached the appropriate size and number, the eggs are scheduled for extraction by follicular puncture.

This procedure is performed in the operating room under ultrasound guidance and sedation to avoid any discomfort.

It lasts about 15-30 minutes and the patient can go home 3-4 hours after the procedure.

The embryology laboratory checks that the eggs have been obtained and that they are mature (able to fertilise and produce an embryo).

After verifying that the eggs are mature, the semen sample or testicular biopsy must be processed.

The semen sample can be from the partner/spouse or from a donor from a certified bank.

It is prepared in the andrology laboratory by sperm capacitation or other sperm selection method to select the best sperm for fertilisation. The sperm are then inseminated by IVF or ICSI. This semen sample used for IVF treatment can be fresh or frozen.

The following day, the number of fertilised eggs is checked and, over the days, the embryos are kept in culture in incubators with temperature and CO2 control. The laboratory staff will keep you informed of the evolution of the process.

Embryo transfer is the deposition of the embryo or embryos into the uterine cavity. The procedure is performed in the operating room, although it does not require sedation and is painless and quick. A limited number (between 1 and 3) of the embryos obtained will be transferred to the uterus with a fine catheter, where they will follow their natural evolution. The remaining viable embryos, if any, will be vitrified for use in further attempts at frozen embryo transfer.

The pregnancy test will be performed about two weeks after the transfer with an evaluation of the beta HCG hormone in the blood.

Do you have questions about In Vitro Fertilisation?

The medication used in an in vitro fertilisation treatment aims to stimulate the ovary to produce several follicles that contain the eggs, but it is adapted to each woman. It is important to carry out a good preliminary study and a good diagnosis so that the medical team can prepare a personalised treatment in the most appropriate way.

It is recommended that only one embryo is transferred to avoid the risk of multiple pregnancy. However, in some cases two embryos are transferred. At a legal level, Spanish law allows the transfer of three embryos, however, this is only done in very exceptional cases.

The best quality embryo or embryos are always transferred. If there are more good quality embryos that are not transferred, they will be frozen. They will be used in future transfers, for example, in case of failure to get pregnant after the first transfer or to search for a second pregnancy.

Can I exercise during ovarian stimulation?

It is not advisable to do impact exercise during ovarian stimulation, as the ovaries increase considerably in size and this can be harmful. Any other type of exercise should be assessed by the medical team on a case-by-case basis.

Slight rest is recommended on the day of the follicular puncture. You may feel discomfort similar to menstruation, but afterwards you can go about your normal life.

You have to go about your normal life, trying to be relaxed and doing activities that bring you wellbeing, but avoiding intense or high-impact exercise. In addition, take the prescribed medication and take care of your diet.

Moderate physical exercise is recommended, as it is good for improving blood circulation in the uterine area, but not intense exercise. It is better to wait for the pregnancy test and check for implantation before swimming at the beach or pool.
