Abstract: Mycotoxins have various effects on human and animal health. Among these, zearalenone is especially toxic for the reproductive system, exerting an estrogenic effect in animals. For the present study, we harvested ovaries from five sows in a pig farm in northwestern Romania. Subsequently, the samples were processed through paraffin technique for histological examination. The ovaries presented numerous follicles in different stages of evolution or involution. None of the antral follicles reached the ovulatory stage, instead they became atretic follicles, undergoing the same physiological processes, but at a higher extent. These findings suggest that consumption of food infested with Fusarium moulds can lead to a significant decrease of the reproductive life of females.
Keywords: apoptosis, atresia, follicle, sow, zearalenone
