The success of intrauterine insemination depends on 2 factors:
The indication for intrauterine insemination (the reason it is being performed).
Whether performed in a drug stimulated or natural (drug free) cycle.
In general intrauterine insemination is a good assisted conception treatment if it is performed to overcome a problem of lack of sperm ie using donor sperm for severe male subfertility. It is also successful if intercourse is not occurring normally such as in cases of ejaculation dysfunction (ED). Intrauterine insemination is moderately successful when used for cervical mucus hostility when sperm are killed within the cervix. Intrauterine insemination tends to be less useful if the indication is male factor subfertility ie low numbers or movement of sperm or in unexplained infertility.
Artificial insemination by husband
Artificial Insemination by husband 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 case of unexplained infertility (idiopathic infertility).
The pregnancy rate with artificial insemination by husband is around 15/18% per treatment cycle.
The women’s age and possible existence of other causes affecting fertility can influence the final results, it is often necessary to undergo more than one cycle in order to obtain a pregnancy, up to 3-4.
Insemination cycles are recommended after unsuccessful cases, it is necessary altering the dose, stricter controls…). If the pregnancy is still not attained, we can move to other ART (IVF, IVF+ICSI).
Artificial Insemination with donor sperm
This is indicated for.
Couples with a sperm disorders.
Couples in which the male partner is at risk of transmitting a disease to his descendants.
Women without a male partner who desire pregnancy.
Before donors are accepted, they undergo rigorous examination to prevent any possible transmission of diseases to descendants. This examination includes a genetic study and a study of infectious diseases (Hepatitis, HIV, AIDS etc).
The pregnancy rate is between 20-25% per treatment cycle. Most pregnancies occur in the first three cycles of insemination, although factors like the women’s age and the possible existence of other causes, that can affect fertility may delay the success of treatment a little danger.
In some cases it is advisable to use ovulation stimulation treatments with oral tablets or subcutaneous to increase the possibilities of achieving pregnancy.
Previous requirements for insemination
Complimentary study to rate out associated pathology that make pregnant difficult or impossible to achieve.
Identification of the donor who best coincides with the physical characteristics (phenotype, eye color…) of the couple or the patient herself.
After insemination, the patient rests for 10-15 minutes. That day we recommend some rest, avoiding immersion baths and sexual relations. The next day she can resume her normal life. In the days after insemination, a little spotting or mild abnormal pain sometimes occurs.
Injection and allergic reaction to sperm.
Components are exceptional complications.
This type of insemination has a 15% risk of miscarriage and 1% risk of extra uterine or ectopic pregnancy.
