What is Unexplained Infertility? How is it treated?
Nearly in 15% of all cases even after the complex male and female medical examinations (including laparoscopic operation), reason of infertility is still unknown. It’s such a known unexplained infertility. Unexplained infertility is one of the most difficult forms of infertility as doctors are unable to define the real reason of it.
Signs of unexplained infertility.
There are several factors which might be signs of unexplained infertility. Among them it’s necessary to point out ovarian and hormonal factors (incorrect development of follicles; absence of ovulation; disorders of the egg structure; genetic disorders of eggs; production of antibodies which destroy the eggs).
Uterine factors like changes of the endometrium structure which influence the process of implantation and increase of activity of the uterine cavity are also significant factors of female fertility.
Unexplained fertility might be also caused by the male factor – structural disorders of the sperm cells (changes of its genetic material) or embryo factors – formation of the bad quality embryos or embryos with genetic and chromosomal disorders.
Fortunately, some of these reasons of unexplained infertility might be diagnosed with modern methods of ART. But, still, most of such factors are impossible to define.
Treatment of unexplained infertility
If unexplained infertility is diagnosed, spouses are suggested various effective kinds of treatment to overcome such type of infertility. Such a choice much depends on age, duration of infertility, previous pregnancies or abortions/miscarriages and, of course, spouses’ desire to become parents.
Two ways of treatment are pointed out: ovarian stimulation with IUI (Intrauterine Insemination) or IVF (In-vitro Fertilization). To avoid polycarpous pregnancy, it’s better not to use IUI if after the stimulation more than 3 follicles bigger than 18mm are formed.
