Abstract Objective PCOS is a heterogeneous endocrine disorder with both reproductive and metabolic abnormalities. At present, PCOS has been confirmed to have a certain genetic background. Compared with healthy women, the vast majority of PCOS patients have hyperandrogenemia, and this excessive androgen exposure during pregnancy may affect the development of female fetuses. The aim of the current study was to investigate the effect of adiponectin intervention during early pregnancy of obese mice with PCOS on the metabolic phenotype of adult female offspring. Methods After the PCOS model was established, C57BL/6J mice were divided into maternal-control, maternal-PCOS, and maternal-PCOS + APN groups. DHEA-induced PCOS mice were supplemented with adiponectin (10 mg/kg/day) in the early pregnancy in order to eliminate adverse hormone exposure and then traced for endocrine indicators in their adult female offspring, which were observed for metabolism syndrome or endocrine disturbance and exhibited the main effects of APN. To further explore the underlying mechanism, the relative expressions of phosphorylated AMPK, PI3K, and Akt were detected in the ovaries of offspring mice. Results The serum testosterone level of the maternal-PCOS + APN group in early pregnancy was significantly lower than that of the maternal-PCOS group (p < 0.01). The serum testosterone level in the offspring-PCOS + APN group was significantly lower than in the offspring-PCOS group (p <0.05), the diestrus time characterized by massive granulocyte aggregation in the estrus cycle was significantly shorter than in the offspring-PCOS group (p<0.05), and the phenotypes of PCOS-like reproductive disorders and metabolic disorders, such as obesity, insulin resistance, impaired glucose tolerance, and hyperlipidemia, were also significantly improved in the offspring-PCOS + APN group (p < 0.05). Compared with the control group, the expression levels of phosphorylated AMPK, PI3K, and Akt in the offspring-PCOS group were significantly decreased (p < 0.05), while those in the offspring-PCOS + APN group were significantly increased (p < 0.05). Conclusions APN intervention in early pregnancy significantly reduced the adverse effects of maternal obesity and high androgen levels during pregnancy on female offspring and corrected the PCOS-like endocrine phenotype and metabolic disorders of adult female offspring. This effect may be caused by the activation of the AMPK/PI3K-Akt signaling pathway in PCOS offspring mice.

Vit C

Background: Dexamethasone (DEX) is a common medicine that is capable of causing malformation in the male reproductive system. The aim of this study was to investigate the effect of vitamin C (Vit-C) on spermatogenesis indexes and daily sperm production (DSP) in adult mice treated with DEX. Methods: Male Naval Medical Research Institute (NMRI) mice were divided into four groups: Control, DEX (7 mg/kg/day), Vit-C (100 mg/kg/day), and DEX +Vit-C and treated for 7 days with intraperitoneal injection. Results: A significant increase in the mean levels of serum and tissue malondialdehyde (MDA) and apoptosis of Leydig cells was found in the DEX group compared to the control group. Sperm motility, DSP, tubular differentiation index, meiotic index, spermatogenesis index, the mean number of spermatocytes, round and long spermatids, and Leydig cells, and also serum testosterone level decreased in the DEX group compared to the control group. The results of this study indicate that Vit-C can significantly prevent the adverse effects of DEX on the mean number of spermatocyte, spermatid, and Leydig cells, tubular differentiation, meiotic and spermatogenesis index, DSP, sperm motility, and the mean levels of serum MDA. Conclusion: In conclusion, our results showed that coadministration of Vit-C and DEX prevents the adverse effects of DEX on the spermatogenesis indexes and DSP.

The aim of this study was to evaluate the effect of age and season on the epididymal sperm and level of testosterone in camel. A total 103 camel testes samples were collected from Al-Najaf slaughter house during a cold season (December 2012, January and February 2013) and moderatehot season (March, April and May, 2013). Testes were divided into 3 Gs according to camel age, G1 included the testes of 2-3years, G 2 (3 – 4years) and over 4 years (G 3). Blood samples were collected for determination of serum testosterone level. The sperms were obtained from the tail of epididymis from all animals groups and the results of the sperms individual motility percentage was increased at the level of (P< 0.05) significantly with age progress in both seasons. Also, sperm motility of G3 recorded a significantly higher than those of G1 and G2 in cold and moderate-hot seasons .The live percentage of G 3 animals was 90.01% in cold season with a significantly higher than those of other Gs and in both seasons. However, the live sperm percentage of G 3 during moderate-hot season was 87.82% and G 2 during moderate-hot and cold seasons were 88.58 and 88.72% respectively, showed significantly higher than those of G1 during cold and moderate-hot seasons .The concentration of sperm obtained from epididymis tail of bulls camel significantly increase with age progress in both seasons. However, the mean of the sperm concentration in cold season showed significance higher than those in moderate-hot season in animals of G 1 and 3, respectively. The abnormal morphologically sperm percentage of animals G 1 in both cold and moderate-hot seasons were significantly higher than those of G3.The testosterone levels of the young animals (under 4 years) increased gradually and reached its peak in February 2.28 ng/ml and March 2.27ng/ml. In the same trend older animal (more than 4 years) was showed 8.14 and 7.35 ng/ml, respectively. The older animals showed a significantly monthly, higher values than those of the younger animals in their testosterone level started from January up to May. In conclusions during cold months the camel over 4 years shows higher percentage of epididymal sperms parameters (live and individual motility) and sperms concentration as well as serum testosterone level.
