Artificial Insemination with Husband’s Sperm [IAH]
Artificial insemination refers to the placement of spermatozoa inside the female reproductive tract at the time of ovulation.
During normal fertilization, spermatozoa are placed in the vagina, from whence only a few spermatozoa are able to swim up through the uterus and then through the Fallopian tube to reach the egg and fertilize it.
During artificial insemination the spermatozoa are instead taken to the laboratory where the ones with the greatest fertilizing potential are selected and then placed through the vagina and high up into the uterus. This is done at the time of ovulation to enhance the chances of fertilization.
In order to be able to do an artificial insemination, the Fallopian tubes, the uterus and the cervix must be normal, so they must be evaluated previously
Who benefits from IAH?
AIH is used when there are abnormalities either in the female genital tract (cervical stenosis) or in the male tract (hipospadias). It is also beneficial when there is mild male factor, unexplained infertility or mild endometriosis.
If artificial insemination is unsuccessful or not an option, in vitro fertilization IVF is another treatment possibility.
For each AIH attempt pregnancy rates vary between 5% and 18%, depending on several factors like:
- Number and quality of the spermatozoa used.
- Quality of the ovarian response.
- Women age.
- Duration of infertility.
Accumulative pregnancy rates around 50% can be obtained after 4 IAH attempts.
