How Effective Is Intrauterine Insemination For Treatment Of Infertility?

intrauterine-insemination-f For many infertile childless couples, intrauterine insemination has come as a ray of hope. The method of intrauterine insemination involves direct placement of sperm into uterus a day after the release of one or more eggs from ovary. After placement, the sperm passes into the fallopian tubes and fertilizes the waiting egg, leading to conception.

Intrauterine insemination mostly used in couples having mild male infertility (known as sub fertility).

If the sperm concentration is found to be below average or if the mobility of sperm is found to be weak or abnormal in size in semen analysis, intrauterine insemination can work effectively in overcoming all such problems.

The procedure of intrauterine insemination can ensure separation of the highly motile and normal sperm from seminal fluid.

Intrauterine insemination can also be effective in case of cervical factor infertility. The cervix existing at the lower end of the uterus facilitates a gap between vagina and uterus.

With vaginal ejaculation the sperm passes through cervical gap to reach uterus and then swims into the fallopian tubes for fertilizing the waiting egg.

The fluid generated by the cervix during ovulation usually facilitates movement of sperm from vagina to fallopian tubes. However, in case the cervical fluid becomes thicker and too viscous it may prevent the sperm from traveling from vagina to fallopian tubes.

The method of intrauterine insemination involves creation of bypasses in the cervix to facilitate the journey of the sperm directly into the uterus and increase the number of sperms available in seminal fluid for impregnation.

Intrauterine insemination can also be used in women who are having infertility due to allergy to semen. In such rare cases women are allergic to seminal proteins as the vaginal skin turns reddish and become swollen and inflamed after coming in contact with semen with vaginal ejaculation.

Such symptoms can not appear if condom is used but it cannot lead to pregnancy. Intrauterine insemination is adopted in such cases for removal of most of proteins from semen before insertion of sperm into uterus.
