Endometriosis and Oocyte Quality

Gynecologic and Obstetric Investigation, 2002
Endometriosis is associated with marked subfertility and various causes for this subfertility have been previously studied. The poor quality of oocytes has been suggested as one possible cause. In this study, we evaluated the quality of oocytes by examining the status of granulosa cells surrounding the oocyte.

Metabolic syndrome and oocyte quality

Trends in Endocrinology & Metabolism, 2011
Metabolic syndrome affects one in four women in the USA, and the incidence is rising every year. Metabolic syndrome is strongly associated with development of coronary artery disease and diabetes. Women of reproductive age are not spared from the complications of metabolic syndrome, which overlaps with obesity and polycystic ovary syndrome (PCOS), both

Anti-Müllerian hormone: a marker for oocyte quantity, oocyte quality and embryo quality?

Reproductive BioMedicine Online, 2008
Serum anti-Müllerian hormone (AMH) concentrations decline with increasing age and constitute a sensitive marker for ovarian ageing. In addition, basal serum AMH concentrations predict ovarian response during IVF cycles. Concomitantly, oocyte quantity and embryo quality decrease with advancing age.

Oocyte quality in assisted reproduction techniques

Minerva Endocrinology, 2022
The metaphase II (MII) oocyte is the mature female gamete, produced from a complex maturation process called oogenesis that starts in the first weeks of embryogenesis in the female embryo tract, continues during puberty, and is completed at fertilization with the spermatozoon. Oogenesis is closely related to folliculogenesis.

Preantral follicle culture and oocyte quality

Reproduction, Fertility and Development, 2017
The formation of high-quality oocytes depends on complex stage-specific interactions between the germ cell and the somatic compartment involving endocrine, paracrine, and autocrine regulation. Cooperativity in bidirectional signalling and metabolism in response to factors in the microenvironment drive growth, proliferation, cell cycle regulation ...

Obesity and oocyte quality

2013
Introduction Obesity has become one of the most urgent nutritional and health issues of our time. Globally, the number of obese people is at a historical high with the incidence continuing to rise. Obesity is prevalent in young women [1] and latest predictions indicate that in the USA and UK 40–50% of women will be obese by 2030 [2].
