BACKGROUND The development of an accurate method for selection of high-quality
embryos is essential to achieve high pregnancy rates with single embryo transfer in human …

Background Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic
disorder in women. The developmental competence of oocytes and embryos in PCOS …

Oocytes become enclosed in primordial follicles during fetal life and remain dormant there
until activation followed by growth and meiotic resumption. Current knowledge about the …

The gain or loss of a chromosome—or aneuploidy—acts as one of the major triggers for
infertility and pregnancy loss in humans. These chromosomal abnormalities affect more than …

BACKGROUND: We determined whether oocyte dysmorphisms, especially repetition of
specific dysmorphisms from cycle to cycle, had a prognostic impact on intracytoplasmic …

Purpose To investigate the association of cumulus cell (CC)-related expression of a selected
cluster of key genes (PTGS2, CAMK1D, HAS2, STC1, and EFNB2) with embryo …

The conventional method of human oocyte maturation in vitro in the presence of
gonadotrophins continues to be a relatively low-success procedure in the assisted …

Purpose To assess the efficiency of IVM in patients with repeated ART failure due to
resistant ovary syndrome or due to deficient oocyte maturation. Methods Clinical and …

Introduction: Male infertility affects about 7% of the general male population, and it is a
multifactorial, polygenic pathological condition. Known genetic factors, accounting for about …

Oocyte quality control culls eggs with defects in meiosis. In mouse, oocyte death can be
triggered by defects in chromosome synapsis and recombination, which involve repair of …
