Disturbed Follicular Microenvironment in Polycystic Ovary Syndrome: Relationship to Oocyte Quality and Infertility.

Endocrinology
Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with infertility and poor reproductive outcomes. The follicular fluid (FF) microenvironment plays a crucial role in oocyte development. This review summarizes evidence elucidating

Production and Quality of Bovine Oocytes and Embryos

Veterinary Research Communications, 2004
Many factors influence the efficiency of the in vitro embryo production technology in cattle but the most important are the physiological conditions of the donor and the culture protocols for oocyte maturation and fertilization and for embryo culture from zygote to blastocyst.

Oocyte Quality in Women with Endometriosis

Gynecologic and Obstetric Investigation
Background: Endometriosis is a chronic gynecological condition that affects approximately 10% of women of reproductive age globally. It is associated with significant morbidity due to symptoms such as pelvic pain and infertility. Current knowledge suggests that endometriosis impacts oocyte quality, a critical factor for successful fertilization and ...

What Criteria for the Definition of Oocyte Quality?

Annals of the New York Academy of Sciences, 2004
Abstract: Although the spermatozoon provides an essential contribution to the generation of a new individual, the developmental fate of the embryo is principally dictated by the oocyte. Oocyte competencies are acquired throughout oogenesis, via the interaction with somatic cells.

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].

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.

Assessment of Oocyte Quality

2012
After oocyte collection for assisted reproductive technologies, the oocytes display various aspects of maturation, integrity and viability. As there is still a lack of reliable and rapid biochemical, or molecular marker of their status, the best modality for evaluation of oocyte quality still remains to be direct microscopic observation of morphology ...
