In the present study, we aimed to address the use of ethyl pyruvate (EP) against the harmful effects of cyclophosphamide (CP) treatment. Thirty-nine adult male mice were divided into three groups including control group received normal saline [0.20 mL per day; intraperitoneally (IP)], CP group received CP (15.00 mg kg-1 per week, IP) and CP+EP group received EP (40.00 mg kg-1 per day, IP) along with CP and treated for 35 days. After preparation of paraffin sections and Hematoxylin and Eosin staining, the histomorphometric studies were performed on the testicular tissue. Additionally, the serum superoxide dismutase (SOD) and testosterone level, testis malondialdehyde (MDA) and in vitro fertilization rate were assessed. The results showed an increase in the tubal differentiation index, repopulation index, spermiogenesis index, thickness of testicular capsule, mean distribution of active Sertoli cells, SOD and testosterone levels of the CP+EP group in comparison with the CP group. Moreover, the MDA levels in the CP+EP group were lower than the CP group. An increase occurred in the percentage of fertilization in the CP+EP group compared to the CP group. Results of this study revealed that the EP ameliorates deleterious side effects of CP on testicular histology and in vitro fertility.

Bisphenol-S (BPS) is a new bisphenol-A substitute widely used in many plastic products. Bisphenol-A as a main member of bisphenol family has been known as an endocrine system disrupter chemical compound. Like other members of bisphenol family, there is public health concern about the toxic effects of BPS on reproductive system, thus, we examined BPS effects on in vitro fertilization (IVF) potential and oxidative stress status in a murine model. Adult female mice (n = 70) were randomly divided into control and BPS-treated groups. Bisphenol-S was administered at doses of 0, 1, 5, 10, 50 and 100 µg kg-1 body weight per day intraperitoneally for 21 consecutive days. Twenty-Four hr after the last treatment, five mice in each group were super-ovulated and the oocytes were harvested for IVF. All ovaries were collected and used for biochemical factors analyses. Bisphenol-S exposure at doses more than 10 µg kg-1 induced developmental arrest of pre-implantation embryos. Further, lipid peroxidation measurement in ovaries indicated that all doses of BPS cause oxidative stress in female mice. In conclusion, BPS administration even in low doses can result in female reproductive toxicities and oxidative stress in mice.

Current study was aimed to evaluating protective effects of cornus mas fruit extract (CMFE) in mice treated with methotrexate (MTX). For this purpose, 48 young mature male mice were divided into 6 groups. Control group received only normal saline (0.1 mLper day, intraperitoneally), and the second group was administered MTX (20 mg kg-1 perweek, intraperitoneally). The third, fourth and fifth groups received MTX daily oral doses of 250, 500 and 1000 mg kg-1 CMFE as well as MTX. The sixth group was only given CMFE with a dose of 1000 mg kg-1 perday, orally, for 35 days. Then, the animals were anesthetically euthanized and the sperms were separated from epididymis. DNA damage level, the amount of malondialdehyde (MDA) as well as in vitro fertility was evaluated. The number of sperms with damaged DNA and MDA level in MTX-treated group showed a significant increase compared to control group (p < 0.05). In groups receiving CMFE along with MTX, DNA damage level and MDA amount suggested a decrease in comparison with MTX group (p < 0.05). Also, in vitro fertilization and embryonic development in MTX-treated group was significantly lower than the control group, and the level of embryonic arresting was higher (p < 0.05). In groups which received CMFE along with MTX, in vitro fertility and embryonic development was higher than MTX group (p < 0.05) and the arrested embryos showed a decrease. This study suggested that cornus mas is able to ameliorate the side effects of MTX.
