Artificial insemination treatment is one of the easier assisted reproductive techniques. It’s about inserting sperm in an unnatural manner in the uterus during ovulation period to achieve pregnancy.

Depending on the source of the sperm we have two types of artificial insemination: with partner sperm (AIH or homologous insemination) or with donor sperm (or heterologous insemination)

Before starting a cycle of artificial insemination it is necessary to verify that the partner meet a number of conditions:

  • Check the patency of the fallopian tubes to ensure the passage of sperm for fertilization and the zygote reaches the uterus.
  • Exclude possible malformations of the uterus through an ultrasound that could affect fertilization, implantation and pregnancy. Make a hormonal analysis, to exclude hormonal diseases.
  • With a semen analysis check that there is a minimum quality of the semen. It must have a minimum of concentration and / or mobility requirements.
  • The age of the woman, which directly affects the success or failure. From the age of 36 is when the pregnancy starts to decrease.
  • Ensure that there is no risk of infection for the partner and / or future baby through a potential risk of hepatitis B or C, HIV, rubella, syphilis and toxoplasmosis.


Artificial insemination with partner sperm is indicated in the following cases:

  • Female sterility:

- Mild or moderate endometriosis

- Ovulatory dysfunction: PCOS, anovulation or problems in the follicular phase

- Cervical factor

- Amendment of anatomic stenosis (narrowing of the cervix), vaginismus

  • Male sterility:

- Mild changes in the parameters of the sperm count and / or mobility fell in sperm.

- Inability to insert semen into the vagina: sexual impotence, retrograde ejaculation, premature ejaculation.

  • Unexplained infertility: studies show normal but no pregnancy is achieved.
  • Immune infertility: the female reproductive system produces antibodies that destroy sperm.

Artificial Insemination with donor sperm is recommended for:

  • Women who are facing motherhood alone.
  • Female homosexual couples
  • Severe male factor:

- Azoospermia: no sperm in the ejaculate

- Severe changes in parameters of sperm: after several cycles of ICSI pregnancy is not achieved.

- Genetic diseases that can not be diagnosed by PGD.

- Sexually transmitted diseases.



Ovarian stimulation
We begin treatment with ovarian stimulation, where we use a number of hormones similar to those produced by the woman herself (gonadotropins). The goal is the development of multiple follicles to abtain a high numer of oocytes and thus increase the chances of success. The stimulation is regularly monitored by ultrasound and blood tests.
Sperm capacitation
On the day of follicular punction, the andrology laboratory has prepared the semen sample (seminal training) by previously selecting sperm washing techniques with greater motility.
When using a semen from a sperm bank we will proceed to the thawing of the sample and the training.
Intrauterine insemination
Insemination is made within the time range in which it is estimated that ovulation will occur. The capacitated sperm are introduced into a tube and injected into the woman’s uterus. This procedure ispainless and women leave the center after an hour of rest and can lead a normal life.
Support during the luteal phase
To facilitate embryo implantation progesterone is administered vaginally, giving support to the luteal phase
Pregnancy test

The pregnancy test will be done trough a blood test 13 days after the follicular puncture.

If the patient has lost blood before undergoing the test it is esencial to never leave the medication and to contact the medical team for advice. Throughout treatment, your personal assistant will be available at all times to resolverle doubts that you may have and support you in this special moment.

You know what…

  • According to the register of the Spanish Fertility Society (SEF), Spain Is now the third country in Europe with artificial insemination treatments. 23,000 inseminations are performed annually within fertility treatments.
  • In the case of AID, sperm donation is anonymous and absolutely legal in Spain, regardless of the nationality or origin of the patient.
  • VITA maintains a partnership with an external sperm bank where semen samples are subjected to rigorous clinical testing.
  • In general, the pregnancy rate of artificial insemination with partner sperm is around 12-20% per cycle, with a cumulative rate after four cycles of 45-50%. For insemination with donor sperm, the results are about 20-30% on the cycle and after four cycles more than 60%.
  • Usually after insemination, the patient waits about an hour in the room at the fertility center. Then, once home, they can carry out their normal life.
  • When a pregnancy is achieved, the development of the pregnancy is normal, the risk of abortion, premature birth or a baby with a birth defect is the same as in a pregnancy through vaginal intercourse.
