Insemination by husband is an assisted reproduction technique (ART) which aims to facilitate the union between the sperm and oocyte (ovule). Normally, once deposited in the vagina during intercourse, the sperm have to cross the entire female genital tract before reaching the fallopian tubes and then the oocyte. With artificial insemination, the sperm is deposited directly inside the uterus or cervix (intrauterine insemination); in other words, closer to the fallopian tubes to reduce the passage before reaching the fertilisation site.
This type of insemination is indicated in:
- Disorders concerning sperm quality and/or quantity.
- Cervical disorders blocking the passage of the sperm from the vagina to the inner genital tract.
- In cases of unexplained infertility (idiopathic infertility).
In all cases, ovulation stimulation treatment is indicated with the aim of ensuring correct ovulation. There are some risks with this treatment (see complications) but the chances of success are high.
The pregnancy rate with artificial insemination by husband is around 15% per treatment cycle.
Factors such as the woman's age and possible existence of other causes affecting fertility can influence the final results, so it is often necessary to undergo more than one cycle in order to attain a pregnancy.
Generally, up to 3-4 insemination cycles are recommended. When a cycle proves unsuccessful it is important to review it and to make the necessary changes (altering the dose, stricter controls...). If a pregnancy is still not attained, the possibility of other abnormalities should be considered, as well as considering other ART.
- Full gynaecological examination.
- Additional tests to rule out any related conditions that may hinder or impede pregnancy.
