Why is A.I.H. not very popular

A.I.H. is inappropriate treatment for the vast majority of infertile couples. Most men have their own very adequately functioning "natural syringe" with which to deposit sperm around the cervix after which the sperm enter the cervical mucus in a matter of seconds.
There are, therefore, very few situations to carry out A.I.H.
 

For whom is A.I.H. advocated

1. Some men have problems of impotence, premature ejaculation and anatomical abnormalities of the penis. In such cases, the men usually have a normal sperm count but are unable to deposit the sperm in the vagina. They can, however, produce a semen sample by masturbation which can subsequently be introduced by A.I.H. If this is the couple's only infertility problem, the success of treatment by A.I.H. is high. 
2. In the previous section, the technique of split ejaculation A.I.H. was mentioned for men with oligospermia. However, it is essential that test show that the sperm count per ml in the first part of the ejaculate is very much higher than would have been the count per ml for the whole semen sample. 

When is A.I.H. not very helpful

A.I.H. is sometimes advocated for men with poor motility and low sperm counts in the hope that introducing the sperm directly into the cervical canal or uterus will save them part of their journey to reach the egg. Unfortunately the success rates for A.I.H. make no difference in such cases.

A.I.H. is also sometimes considered for couples who have shown the presence of a cervical mucus hostility factor. Here too, the results have been disappointing.
