Abstract Study question Do serum progesterone levels on the day of embryo transfer (ET) have an impact implantation and pregnancy outcomes? Summary answer Serum luteal were not associated with outcomes under condition utilizing 60mg intramuscular for support in artificial cycles. What is known already It was recognized that circulating level might be frozen-thawed (FET) success, a above certain...

ObjectiveTo determine whether vaginal progesterone for programmed endometrial preparation is noninferior to intramuscular in terms of live birth rates from frozen embryo transfer (FET).DesignThree-armed, randomized, controlled noninferiority trial.SettingMulticenter fertility clinic.Patient(s)A total 1,346 volunteer subjects planning vitrified-warmed high-quality nonbiopsied blastocysts were sc...

Translocation is one of the more common structural rearrangements of chromosomes, with a prevalence of 0.2%. The two most common types of chromosomal translocations, Robertsonian and reciprocal, usually result in no obvious phenotypic abnormalities when balanced. However, these are still associated with reproductive risks, such as infertility, spontaneous abortion and the delivery of babies wit...

Intercourse during an IVF cycle has the potential to improve pregnancy rates since exposure to semen is reported to promote embryo development and implantation in animals. Conversely, coitus-induced uterine contractions or introduction of infection may have a detrimental effect. A multicentre prospective randomized control trial was conducted to determine if intercourse during the peri-transfer...

BACKGROUND We have previously shown that the medium used for culturing IVF embryos affects the birthweight of the resulting newborns. This observation with potentially far-reaching clinical consequences during later life, was made in singletons conceived during the first IVF treatment cycle after the transfer of fresh embryos. In the present study, we hypothesize that in vitro culture of embryo...

background: repeated implantation failure (rif) is a major challenge in reproductive medicine and despite several methods that have been described for management, there is little consensus on the most effective one. objective: this study was conducted to evaluate the effectiveness of platelet-rich plasma in improvement of pregnancy rate in rif patients. materials and methods: twenty women with ...

<b><i>Background:</i></b> The recent studies have shown that sildenafil citrate can enhance estrogen-induced proliferation of the endometrium in infertile women. <b><i>Objective:</i></b> This study was aimed to investigate whether could affect pregnancy outcomes women receiving frozen-thawed embryo transfer (FET) after resection intrauterine adhes...
