A computational biology approach to improve in-vitro folliculogenesis [PDF]
, 2021 Study question Considering the complexity of mechanisms involved in mammalian ovarian folliculogenesis, how about improving the current in-vitro folliculogenesis (ivF) protocols to prolong individual reproductive chance?

Brazilian Journal of Biology, 2009 Chondrichthyes have become an important economic resource in recent years. In spite of this importance, there is little knowledge about their reproductive biology, especially of species from the south-western Atlantic.

Endometriosis and polycystic ovary syndrome are diametric disorders
Evolutionary Applications, 2021 Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of ...

Folliculogenesis in the bovine [PDF]
Theriogenology, 1982 Abstract During the follicular phase of the estrous cycle in the cow, there is a rapid turnover in large (ovulatory size) follicles with the ovulatory follicle being identifiable by size not more than 3 days prior to estrus. Characteristics of the ovulatory follicle have been described in terms of steroid production and, to a lesser extent ...

Frontiers in Endocrinology, 2018 In teleosts, the onset of puberty in females is marked by the appearance of the first wave of pre-vitellogenic (PV) follicles from the pool of primary growth (PG) follicles (follicle activation) in the ovary during sexual maturation.

The effects of phthalates on the ovary
Frontiers in Endocrinology, 2015 Phthalates are commonly used as plasticizers in the manufacturing of flexible polyvinyl chloride products. Large production volumes of phthalates and their widespread use in common consumer, medical, building, and personal care products lead to ...

A pilot study on transcriptome data analysis of folliculogenesis in pigs
Animal, 2009 Three different stages of pig antral follicles have been studied in a granulosa-cell transcriptome analysis on nylon microarrays (1152 clones). The data have been generated from seven RNA follicle pools and several technical replicates were made.

Apoptosis during folliculogenesis in pigs [PDF]
Bioscientifica Proceedings, 2020 The number of female germ cells in pig fetuses decreases by 70% between day 50 after mating and day 300 after birth. Approximately 55% of antral follicles undergo degeneration (atresia) except during the 3 days before oestrus, when only 15% of the follicles survive to ovulate.

, 2022 Polycystic ovary syndrome (PCOS) has been linked to aberrant folliculogenesis and abnormalities in the aromatase enzyme (Cyp19a1) and the steroidogenic enzyme, 17-alpha-hydroxylase (Cyp17a1) expression.
