Leukemia Inhibitory Factor a Marker of Implantation Success in Unexplained Infertility: a Randomized Controlled Trial.

Background: Uterine receptivity and implantation are complex processes requiring coordinated expression of molecules by zygote and uterus. Leukemia inhibitory factor (LIF) is one of the most important cytokines in the reproductive tract. Without expression of LIF in the uterus, implantation of a blastocyst cannot begin.

Comparative Study between Monopolar Electrodes and Bipolar Electrodes in Hysteroscopic Surgery.

Background: The hysteroscopic surgery has become a simple and safe technique, with the use of small hysteroscopes and bipolar energy with trained surgeons, which can prevent abortions and probably increase fertility.

Aim: The study was conducted to evaluate the outcomes after hysteroscopic surgery by using uninopolar or bipolar electrodes.

Setting And Design: At the department of Obstetrics and Gynaecology, Qena university hospital and is a prospective non randomized clinical study.
