BackgroundIn assisted reproductive technology, preventing premature ovulation is crucial for achieving successful pregnancy outcomes. The traditional GnRH antagonist protocol is commonly used to suppress the luteinizing hormone (LH) surge, …

BACKGROUND: In vitro fertilization-conceived babies, even singletons, are at a higher risk of poor birth outcomes such as low birthweight and preterm birth than naturally conceived counterparts. It remains unclear as to what extent these ad…

This study aimed to investigate the metabolite profile and inflammatory state of follicular fluid (FF) in women with stage III-IV ovarian endometriosis (OE) who underwent in vitro fertilization (IVF). A cohort of 20 consecutive patients wit…

Background: The potential correlation between progestin-primed ovarian stimulation (PPOS) and the risk of compromised embryo competence still lacks sound evidence. Methods: A large retrospective cohort study was used to compare the incidenc…

Ectopic pregnancy (EP) is increasingly found in women treated with in vitro fertilization and embryo transfer (IVF−ET). With the development of the freeze-all policy in reproductive medicine, it is controversial whether frozen embryo transf…

BackgroundHydrosalpinx has a negative effect on the pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET), and the pretreatment for hydrosalpinx play an important role in improving the outcomes of IVF-ET. This study aime…

PurposeThe purpose of this study is to assess the safety of progestin-primed ovarian stimulation (PPOS) protocol regarding the neonatal outcomes and congenital malformations in babies born after in vitro fertilization (IVF) and frozen embry…

We present in this paper an in-depth study and analysis of bronchiectasis haemoptysis by multirow CT tomography and a multifaceted treatment and analysis of the interventions monitored by the scan. Although coronary CT is of great clinical …

Methods: 450 infertile patients with severe endometriosis undergoing IVF/ICSI were randomized to: medroxyprogesterone acetate +hMG; dydrogesterone+hMG; and progesterone +hMG. Ovulation was induced with a gonadotropin-releasing hormone agoni…

BACKGROUND: This study investigated the effects of medroxyprogesterone acetate (MPA) on the oocytes and embryos in patients with advanced endometriosis who had a normal ovarian reserve and tubal infertility and received controlled ovarian h…

Objective: Progestin was recently used as an alternative of gonadotropin-releasing hormone (GnRH) analog for preventing premature luteinizing hormone (LH) surge with the aid of vitrification techniques, however, limited data were available …

IntroductionHerlyn-Werner-Wunderlich syndrome (HWWS) is a rare congenital abnormality of the urogenital tract characterized by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. It is usually diagnosed after menarche, …

BACKGROUND Increasing the success rate of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) is a duty of clinicians that has made many seek a variety of protocols. This study was undertaken to use a liquid chromatography-ma…

This study investigated the use of medroxyprogesterone acetate (MPA) or a short protocol for controlled ovarian hyperstimulation (COH) in patients with advanced endometriosis who have normal ovarian function, and to compare cycle characteri…

BACKGROUND The aim of this study was to investigate the effect of natural cycle (NC) endometrial preparation for frozen-thawed embryo transfer (FET) in women with advanced endometriosis. MATERIAL AND METHODS This retrospective study include…
