Intrauterine insemination

Intrauterine insemination - what is it and what is different from IVF?

This manipulation is the artificial introduction of processed sperm into the woman's uterus. This procedure is far from new. It has been used in clinical medicine for 200 years in order to give a chance to become pregnant and take out a child to a woman who can not do it in a natural way. By the way, the documents on the first such procedures date back to 1770.

For intrauterine insemination from the husband, there are such indications:

  1. Subfertility of the sperm, that is, a decrease in its fertilizing ability.
  2. Ejaculatory-sexual problems.
  3. Necessity of cryopreservation of sperm.

From the woman's side, the indications for a VMI are:

  1. Cervical infertility, that is, a change in the properties of the mucous membrane of the uterus, preventing the penetration of a sufficient number of spermatozoa into it.
  2. Vaginismus. So gynecologists call the reflex contraction of the muscles of the vagina for fear of sexual intercourse.
  3. Endometriosis.
  4. Ovulatory dysfunction.
  5. Infertility with an unexplained genesis.

In addition to indications, there are also contraindications to such manipulation. These are mental illnesses, pathology of the uterus and malformations of its development, ovarian tumors, Malignant neoplasms and acute inflammatory ailments of any localization.

The procedure for intrauterine insemination has several advantages over ordinary sexual intercourse as a method of conception. The introduction of the sperm of the husband directly into the uterus allows you to control ovulation and ensure the fusion of spermatozoa and eggs in the optimal period for fertilization. Also, the processing of sperm before such a procedure can improve its quality, increase the chances of pregnancy. Another advantage of the VMI is its availability. It is a cheap alternative way to combat infertility, in which there are no consequences. It is effective, simple, does not require special training.

Intrauterine insemination is a painless procedure. After all, male sperm is injected with a special catheter with a small diameter. It passes through the cervical canal unimpeded.

The manipulation itself takes no more than two minutes. After doing this procedure, the woman should lie down about half an hour.

It is worth noting that the success of the IUI procedure depends on such factors:

  1. The root causes of infertility.
  2. The age of the partners.
  3. Duration of infertility.
  4. The parameters of male sperm.

Reprotologists recommend that no more than three or four attempts of intrauterine insemination be carried out. If they do not give the desired result, then it is necessary to proceed to the procedure of in vitro fertilization. What is its difference from insemination? The main difference is, that with VMI conception (the fusion of male and female sex cells) occurs within the female body (in the uterus). But the procedure of IVF involves the removal of an egg from a woman's ovary, the fence of her husband's sperm, their artificial fusion, that is, the formation of an embryo and its subsequent replanting to a woman. In vitro fertilization is a longer procedure. Only the stage of cultivation of embryos lasts five to six days. And their replanting occurs on 3-5 days. Usually no more than two embryos are transferred to the uterus. Thus, the chances are increasing that one of them will get accustomed. Although quite often take root both, and a woman carries two babies at once.
