Recurrent implantation failure (RIF) refers to two or more unsuccessful in vitro fertilization
embryo transfers in the same individual. Embryonic characteristics, immunological factors …

Primary ovarian insufficiency (POI) can lead to menstrual disturbance, resulting in ovarian
dysfunction before age 40. Prevalence of POI is usually less than 1%; however, ethnicity or …

Background The results of studies on the association between polymorphisms in the FSHR
gene and the risk of POR undergoing IVF have been inconsistent with each other, so we …

Background Whether follicle-stimulating hormone receptor (FSHR) polymorphisms are
implicated in premature ovarian insufficiency (POI) remains controversial. Thus, we …

Objective To investigate whether common genetic polymorphisms are associated with
gonadotropin levels after down-regulation with daily gonadotropin-releasing hormone …

The single nucleotide polymorphism p. N680S of the follicle-stimulating hormone (FSH)
receptor (FSHR) is a discrete marker of ovarian response but previous in vitro studies failed …

Methods: In this prospective case-control study, we enrolled 106 infertile and 164 unrelated
healthy control individuals. Genomic DNA was extracted from the 5 ml of venous blood using …

Purpose The purpose of this study was to investigate whether the follicle-stimulating
hormone receptor (FSHR) gene p. Thr307Ala (c. 919A> G, rs6165) and p. Asn680Ser (c …

Although the impact of polymorphisms 919A> G and 2039A> G of FSHR gene in normal
ovarian function is almost clear, in Premature Ovarian Failure (POF) it still remains elusive …

Premature ovarian failure (POF) is an ovarian defect characterized by the premature
depletion of ovarian follicles in individuals< 40 years old, and is a major cause of infertility in …
