Partner’s artificial insemination (PAI)


Artificial insemination is a technique which consists in depositing the partner’s sperm to the inside of the patient’s uterus.

Initially, the patient must undergo hormonal treatment (although it may also be done in natural cycles) in order to achieve growth and follicular maturation (maturation of the egg).

This treatment can last between 10 and 14 days and it is simple and slightly aggressive, since the dosages of medication given tend to be low.

Once oocyte maturation has been achieved (proved by periodic ultrasound controls performed during the treatment), ovulation is provoked within the next 36 hours and, at such time, the patient will bring the sperm sample to perform insemination.

The sample preparation consists in washing it in order to remove any seminal plasma and non-motile or morphologically altered sperm. In this way, there is only good motile sperm, capable of fertilizing the egg.

Once the sample is prepared, it is placed into an insemination cannula and is left inside the patient’s uterus. The procedure is simple, quick and little painful.

Once finished, the patient will remain lying down for some minutes.

Insemination is a technique which does require neither rest nor change of life habits of the patient.

After treatment, within fifteen days, the patient will take a pregnancy test to know if pregnancy has been achieved.
