Effect of Intra Uterine Granulocyte Colony Stimulating Factor vs. Human Chorionic Gonadotropin at Ovum Pick Up Day on Pregnancy Rate in IVF/ICSI Cases With Recurrent Implantation Failure.

Objective: Recurrent implantation failure is defined as failure to achieve clinical pregnancy after the transfer of four or more good-quality embryos in a minimum of three fresh or frozen cycles in a woman aged less than 40 years. The objective is to compare between the effect of intrauterine G-CSF, hCG, and saline solution injection (as placebo) at the day of ovum pick-up on clinical pregnancy, chemical pregnancy, implantation, and miscarriage rates in patients with recurrent implantation failure undergoing IVF/ICSI.

Methods: This prospective, double blind, parallel, randomized controlled trial included 150 patients equally divided into 3 groups, each containing 50 individuals.

Effect of amlodipine on blood flow of preovulatory follicle in women with clomiphene resistant polycystic ovaries: a randomized controlled trial.

Objective: To detect whether amlodipine could increase pre-ovulatory follicular blood flow, thus enhancing ovulation and creating a better chance of conception in women with PCOS.

Methods: 165 women were screened of which 124 were qualified and women were equally randomized to 62 receiving clomiphene citrate and amlodipine and 62 receiving clomiphene citrate and placebo. The primary outcome was to detect if amlodipine can improve pre-ovulatory follicle blood flow studied by colour and power Doppler Pulsatility index of ovarian arteries, with drug administration.
