The level of 17-beta estradiol in follicular fluid for patients undergoes IVF as correlation with the pregnancy rate


Estradiol (E2) is a steroid hormone produced mainly by the ovary and placenta and in small amounts by adrenals and testes. Estradiol is in equilibrium with estrone, which can be converted to estriol by the liver and placenta. Like for LH-FSH-progesterone, measurement of estradiol concentration is an essential biochemical tool for the investigation of fertility. So that this study was done to assess the follicular fluid E2 in early follicular phase as a predictor of pregnancy rate among females undergoing in vitro fertilization (IVF) in Iraqi patient. The study population consisted of women undergoing in vitro fertilization and aged between 18 - 45 years. The medical records of 56 infertile patients undergoing IVF in the program at center of Baghdad center in the period between February 2015 and July 2015.This study resulted in a pregnant women were 11 (20%) while the non-pregnant women were 45 (80%). The mean levels of E2 fluctuated among different age groups showing significantly with age >35 as compared with another group. The mean levels of E2 in follicular fluid fluctuated among different BMI groups showing that mid 30 year women had more chance to have pregnancy through IVF, and there's no significant between pregnant and non-pregnant. When related to BMI, IVF result showed that the chance of IVF success increased with decreased BMI. This implies that slim women had more chance to have pregnancy through IVF. Furthermore, level of E2 in follicular fluid couldn't be used in IVF as a predictor success of pregnancy.
