“…The histopathological alterations due to BPA exposure could also be another factor affecting the negative changes in semen quality. Previous studies reported similar results that BPA could cause necrosis, seminiferous tubule degenerations or aplasia and giant cell formation (10). BPA increased the number of apoptotic cells in the seminiferous tubules (41).…”

This study aimed to investigate the possible reproductive toxicity dose of bisphenol A (BPA) in male New Zealand white rabbits. Prior to the experiment, male rabbits (n = 24) were acclimatized to laboratory conditions and trained for semen collection for 14 days. After the training period, rabbits were divided into 4 groups of 6: positive controls and 3 different doses of BPA (10, 20 and 100 mg/kg/day). All treatments were administered by oral gavages for 9 weeks following the training period. At the end of the study, BPA negatively affected the serum testosterone, testicular superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and malondialdehyde (MDA). Sperm concentrations and percent progressive motility were significantly declined in BPA treated rabbits. LOAEL value of BPA for reproductive parameters was 10 mg/kg/day.

“…There are studies that focus on the health properties of pumpkin seed oil. Other studies involving animals have shown that pumpkin seed oil protects against the genotoxicity caused by bisphenol A and azathioprine [30,31]. It was also found that pumpkin seed oil is characterized by antihypertensive and cardioprotective effects.…”

The Profile of Secondary Metabolites and Other Bioactive Compounds in Cucurbita pepo L. and Cucurbita moschata Pumpkin Cultivars

Plants and animals are sources of various bioactive compounds that exhibit a broad spectrum of health-promoting effects. Scientists continue studies on the chemical composition of many products in search of foods with high nutritional value. The pumpkin (Cucurbita sp.) is unquestionably a source of valuable nutrients. This vegetable is well-known all over the world and it is appreciated due to its high content of carotenoids, but it is still not much used in the processing industry. The aim of present study was to compare the flesh of 15 pumpkin varieties belonging to the Cucurbita pepo and C. moschata species in terms of the bioactive compound content (carotenoids, phenolic acids, flavonols, minerals and vitamins) and to demonstrate whether the variety has an effect on the chemical composition. To date, no such extensive research has been carried out in this area. The research revealed that the pumpkin pulp had high content of carotenoids. In nearly all cases lutein was the most abundant carotenoid. Numerous phenolic acids and flavonols were also identified. All the cultivars contained gallic acid, protocatechuic acid, 4-hydroxybenzoic acid, vanillic acid, chlorogenic acid, caffeic acid, and rutin. The pumpkin pulp also contained alpha- and gamma-tocopherol. No beta- or delta-tocopherol was found. Potassium, calcium, and sodium were the most abundant minerals. The research also proved that the profile of bioactive compounds in the pumpkin pulp was considerably diversified and depended on the species and cultivar

“…It has been shown that DNA damage could reduce the success of in vitro fertilization (IVF) (Wdowiak et al, 2015) and intracytoplasmic sperm injection (ICSI) (Avendaño et al, 2010), weakens pregnancy (Carlini et al, 2017), and even affects the offspring's health (Jin et al, 2015). Comparative studies of spermatozoa from clinical patients and laboratory animals found that BPA may be associated with declined semen quality and increased sperm DNA damage (Toyama & Yuasa, 2004;Meeker et al, 2010;Vitku et al, 2016;Fawzy et al, 2018;Omran et al, 2018). However, the underlying mechanism for the impacts of BPA on sperm DNA damage is still unclear.…”

Effects of bisphenol A exposure on DNA integrity and protamination of mouse spermatozoa

et al. 2019

Background Bisphenol A is widely used in the manufacture of polycarbonate plastics and has caused increasing concern over its potential adverse impacts on spermatogenesis. However, the effect of bisphenol A on spermiogenesis is yet to be explored. Objectives To evaluate whether bisphenol A has adverse effects on DNA integrity and protamination of spermatogenic cell. Materials and methods Newborn male mice were subcutaneously injected with bisphenol A (0.1, 5 mg/kg body weight, n = 15) or coin oil (control group, n = 20) daily from post‐natal day 1 until 35. At post‐natal day 70, epididymis caudal spermatozoa and testes were collected. Sperm count, sperm motility, and sperm morphology were analyzed. The sperm chromatin structure assay was performed to examine the sperm DNA fragmentation. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method was used to assess apoptosis of spermatogenic cells. The ultrastructural features of testicular sections were examined under a transmission electron microscope. Western blot and RT‐PCR were used to detect the expression levels of transition protein (Tnp) 1 and Tnp2, protamine (Prm) 1 and Prm2 protein, and mRNA in mice testes. Results Bisphenol A significantly reduced sperm counts, impaired sperm motility, and increased the percentage of malformed spermatozoa. Poor sperm chromatin integrity and increased TUNEL‐positive spermatogenic cells were also observed in mice exposed to bisphenol A. Ultrastructural analysis of testes showed that bisphenol A exposure caused incomplete chromatin condensation, retention of residual cytoplasm, and abnormal acrosome formation. In addition, the relative expression levels of Tnp2 and Prm2 in mice testes decreased significantly in bisphenol A groups. Discussion and conclusion Our findings identified that neonatal bisphenol A exposure may negatively contribute to the sperm quality in adult mice. Mechanistically, we showed that bisphenol A reduced sperm chromatin integrity along with increased DNA damage, which may be due to poor protamination of spermatozoa.
