In the case of heterosexual couples where the woman is finding it difficult to conceive, before artificial insemination is turned to as the solution to impregnate a woman, doctors will require an examination of both the male and female involved in order to remove any and all physical hindrances that are preventing them from naturally achieving a pregnancy.
IUI is a treatment we utilize for a variety of causes of infertility. In particular, couples with unexplained infertility, cervical factor infertility, endometriosis-associated infertility and male factor infertility can be treated by this technique. We have found that very severe male factor infertility is not effectively treated by IUI so men with extremely low sperm counts or motility are generally advised proceeding with this treatment. With natural intercourse many of the ejaculated sperm never make it past the cervix up to the fallopian tubes where fertilization takes place.
