Intrauterine Insemination Clinic

Intrauterine artificial insemination is an assisted reproduction treatment that consists of the introduction of sperm (previously processed and selected in the laboratory) into the woman’s uterine cavity and in the period close to ovulation. Artificial insemination can be performed with the partner’s/spouse’s sperm, or with donor sperm from a certified sperm bank.

Intrauterine Insemination procedure

Intrauterine artificial insemination is carried out after hormonal treatment to stimulate the ovaries. The purpose of this treatment is to obtain the development of one or more follicles, inside which the eggs are found. The process of ovarian stimulation is monitored by vaginal ultrasound scans, which show the number and size of the developing follicles. Once an adequate development has been obtained, other medications are administered to achieve the final maturation of the eggs and to programme the most appropriate moment to perform the insemination.

Intrauterine insemination can be performed on the indicated day with the partner’s/spouse’s sperm, or with donor sperm from a certified bank. Whether it comes from the couple’s fresh sperm, or from a donor with a frozen sample, the semen will be processed by sperm capacitation in the andrology laboratory to select the sperm with the best motility.

These sperm are introduced into the uterus with a flexible catheter in a simple, painless procedure without sedation. After insemination, the patient will receive hormone treatment to promote the development of the pregnancy. The pregnancy test will be performed about two weeks after insemination with an evaluation of the beta HCG hormone in the blood.

Do you have questions about intrauterine insemination?

Insemination is a simple procedure that consists of introducing the sperm into the vagina. Once inside, the process follows the same process as in nature. Fertilisation takes place there and the embryo develops into a pregnancy.

Artificial insemination is performed after a mild hormonal treatment to stimulate the ovaries. The treatment lasts between 7-10 days and when the follicles containing the eggs are of adequate size, medication is administered to produce ovulation and schedule the insemination.

It is not necessary to rest after insemination. You can go about your normal life, it is even recommended. Movement helps the blood circulation in the uterine area. It also helps you to be more distracted and not to think about the result.

The pregnancy rates given by the Spanish Fertility Society for couple artificial insemination (CAI) are 15-20%. For donor artificial insemination (DAI) it is 20-30%.

It is possible to become a single mother through this treatment. Spanish law 14/2006 on Assisted Reproduction allows a woman to become a mother without a male partner. Sperm from an anonymous donor from an authorised bank will be used for this purpose, depending on the patient’s personal characteristics.
