The correlation between basal follicular hormone levels and intracytoplasmic sperm injection results

Intracytoplasmic sperm injection (ICSI) is an assisted reproductive technic widely used for the treatment of male originated infertility. The goal in assisted reproductive technics is to obtain quality oosite and embryo by using appropriate treatment protocols and methods. The pool of germ cells in the ovaries decreases by age. However the ovary reserves that decrease in parallel with increased age in women cause the decrease in the response to the stimulation applied by gonodotrophines and negatively affects the chances of success in treatment. In years, the ovary progressively looses the follicle pool and inhibin level decrease, conversely the follicle stimulating hormone (FSH) releasing increase from adenohypophysis. For this reason the FHS values measured in the early phase are accepted as an important indicator of the ovary reserves. FSH value also carries importance for the ovulation of quality oosits in addition to the oosit reserves. There are several reports that basic FSH value can be used as an important indicator having affected on the pregnancy results in the in vitro fertilization (IVF) applications.This study aims to examine the effects of the basal FSH level in women on the ICSI results. 99 couples accepted for ICSI treatment were included in our study. The patients were grouped into four with basal FSH < 10 IU/ml, FSH >10 IU/ml women and normo spermic patients and basal FSH <10 IU/ml, FSH >10 IU/ml women and oligospermic patients. The oosit numbers in the groups with basal FSH value < 10 IU/ml normosperm and oligosperms and the metaphase II (MII) oosit counts were found to have increased relative to the two groups with FSH values >10 IU/ml and there was statistical significance between the groups. There was no statistical significance between metaphase I (MI) and germinal vesicule (GV) oosit development, fertilization rates and between the good and bad quality ratios of the following embryos in the 2nd and 3rd days. Pregnancy rates were 33.3 in the normosperm group and 40.0 with oligosperm groups with FSH < 10 IU/ml and 18.8 and 26.7 respectively in the FSH >10 IU/ml groups. Even though there was reduced pregnancy in the group with basal FSH values >10 IU/ml a statistical significance was not observed.
