Background: This study intends to present the role of rescue in vitro maturation (IVM) in polycystic ovarian syndrome(PCOS) patients undergoing in vitro fertilization (IVF) treatment who have inappropriate responses to ovarianstimulation.Materials and Methods: This was a retrospective case series study of five PCOS patients undergoing IVF treatmentconsidered for cycle ca...

OBJECTIVE To compare the pregnancy outcomes achieved by in vitro fertilization (IVF) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (PORs). MATERIALS AND METHODS In this randomized controlled trial, 77 PORs undergoing IVF were selected and divided into two groups. First group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...

Summary Statements1.The particular follicle-stimulating hormone formulation used for ovarian stimulation does not affect the incidence of hyperstimulation syndrome. (I)2.Coasting may reduce severe (III)3.Coasting longer than 3 days reduces in vitro fertilization pregnancy rates. (II-2)4.The use either luteinizing or human chorionic gonadotropin final oocyte maturation influence (I)5.There is no...

Background This research investigated the response of vascular active factors, vascular endothelial growth factor (VEGF) and angiotensin-II (AT-II) to ovarian stimulation during 24 hours in patients with polycystic ovary syndrome (PCOS). MaterialsAndMethods In this clinical trial study, 52 patients with PCOS and 8 control cases were stimulated with human chorionic gonadotropin (HCG) on the 4th ...

There is a high incidence of chromosome abnormalities in human embryos that leads to failed IVF cycle. Different studies have shown maternal age the determining factor appearance chromosomal alterations embryo. However, possible influence ovarian stimulation on oocyte and embryo aneuploidies mosaicism controversial. A retrospective study was carried out which 835 from 280 couples undergoing rep...

The time course of chorionic gonadotropin stimulation of nuclear basic and acidic protein biosynthesis, phosphorylation, and acetylation as well as DNA biosynthesis in ovaries of immature rats has been investigated. After injection of radioactive precursor and chorionic gonadotropin into immature rats, ovarian histone fractions Fl, FZal, F2a2, F2b, and F3 were isolated by selective acid extract...

Hypogonadotropic hypogonadism is defined as a medical condition with low or undetectable gonadotropin secretion, associated with a complete arrest of follicular growth and very low estradiol. The main cause can be traced back to an irregular or absent hypothalamic GnRH secretion, whereas only a minority suffers from a pituitary disorder. The choice of treatment to reverse this situation is a pu...

Corifollitropin alfa is a synthetic recombinant follicle-stimulating hormone (rFSH) molecule containing a hybrid beta subunit, which provides a plasma half-life of ∼65 hours while maintaining its pharmocodynamic activity. A single injection of corifollitropin alfa can replace daily FSH injections for the first week of ovarian stimulation for in vitro fertilization. Stimulation can be continued ...
