Polycyclic aromatic hydrocarbons in human granulosa cells: first in vivo presence and positive correlation with body mass index and in vitro ovarian cell steroidogenesis regulation.

Polycyclic Aromatic Hydrocarbons (PAHs) exposure leads to disorders reported in female infertility patients. Our hypothesis is that PAHs accumulate in granulosa cells (Gc) according to body mass index (BMI) and directly affects its functions. All 16 high-priority PAHs were in human FF, Gc and blood plasma with the highest concentration in Gc (GC-MS/MS).

New aspect on the regulation of in vitro oocyte maturation: role of the obesity, neuropeptides and adipokines.

Oocyte quality determinants and nuclear and cytoplasmic maturation establish essential processes for fertilization and further development of the conceptus. Moreover, female fertility is strongly dependent on the metabolic status of the organism. Numerous sources indicate that obesity impairs ovarian function including oocyte physiology by inhibiting nuclear maturation, stimulating lipotoxicity and inflammation, enabling cumulus cells apoptosis, promoting reactive oxygen species formation and ultimately imposing pathogenic effects on mitochondria leading to infertility.

What's new in reproductive biology? Report from the 10th Meeting of the Society for Biology of Reproduction (Towarzystwo Biologii Rozrodu, TBR).

The 10th Meeting of the Society for Biology of Reproduction (Towarzystwo Biologii Rozrodu, TBR) was held on September 12th-14th, 2024 in Warsaw, Poland. It was a continuation of previous meetings since 1999, when the first Meeting was held in Mierki near Olsztyn. As in previous meetings, the conference brought together an outstanding group of nearly 140 researchers, all connected by their work in reproductive biology across various animal models.
