Diabetes in a long period can damage the testicular tissue and impair the male fertility potential. Recently, different herbal treatments have been used for the prevention of type I diabetes and its pathological effects. Methanolic extract of Equisetum arvense has anti-oxidant and hypoglycemic properties. Thus, the current study aimed to evaluate the protective effects of Equisetum arvense methanolic extract (EE) on diabetes-induced detrimental effects in mice testicular tissue. Thirty-two adult male mice were randomly divided into four groups including control-sham, diabetic (induced by streptozotocin, 50.00 mg kg-1 for five days), diabetic + EE 250 (250 mg kg-1) and diabetic + EE 500 (500 mg kg-1). After 45 days, all animals were euthanized and their testicles were dissected out and undergone histological analyses. Moreover, the serum level of testosterone was evaluated. Analyses showed that seminiferous tubules diameter, Leydig cells number per mm2 of the connective tissue, Sertoli cells number per tubule, serum level of testosterone and percentage of seminiferous tubules with positive tubular differentiation, repopulation and spermiogenesis indices were significantly decreased in the diabetic group in comparison with control-sham group. The administration of EE in test groups significantly decreased the adverse effects of diabetes (especially 500 mg kg-1). The results of this study revealed that diabetes disturbs spermatogenesis and spermiogenesis processes in mice. Meanwhile, the EE prevents diabetes-induced damages in mice testicular tissue, which may be associated with its hypoglycemic and antioxidative activities.

Ethephon (C2H6ClO3P; ETP), an organophosphorus pesticide regulating plant growth, is widely used for early ripening of fruits and vegetables in agriculture. The aim of this study was to investigate the effects of ETP on histomorphometrical and biochemical parameters in mouse testicular tissue. In this study, 90 adult male mice were randomly divided into six equal groups (n = 15). The ETP was administered orally at different doses (120, 240 and 480 mg kg-1) daily for 35 days. Untreated control, sham (received only normal saline) and neostigmine bromide-treated (positive control; 0.10 mg kg-1 orally; once per week) groups were also considered. Following 35 days, animals were euthanized and testicle and serum samples were taken. Accordingly, blood and serum acetylcholinesterase (AChE), catalase, total antioxidant capacity (TAC) and malondialdehyde (MDA) levels as well as histomorphometrical changes of testicles were investigated. The ETP-administered animals represented a significant reduction in AChE, TAC and catalase levels and remarkable increment in MDA content. A marked reduction was also seen in the germinal epithelium height, connective tissue thickness, seminiferous tubules diameter and Leydig cell number as well as spermiogenesis and Sertoli cell indices in ETP-treated mice compared to control ones. Similar findings were found in neostigmine bromide-treated animals. In conclusion, the ETP significantly affects the serum and blood anti-oxidant statuses and results in severe histological damages both at germ and somatic cell levels, suggesting its hematotoxic and reprotoxic characteristic.

One of the side effects of cyclophosphamide (CP) is low fertility. In this study, we investigated the protective role of crocin (Cr) against CP chemotherapy-induced changes in ovarian tissue. In the current study, we treated 15 female mice aged 6-8 weeks old for 21 days. The mice were distributed into three groups including control received normal saline (0.10 mL; IP), CP or sham-control group (CP once a week, 15.00 mg kg-1; IP) and experimental (CP + Cr) group received CP along with Cr (200 mg kg-1 daily; IP). After completing the procedure, levels of total anti-oxidant capacity (TAC), superoxide dismutase (SOD) and sex hormones in serum as well as malondialdehyde (MDA) in the left ovarian tissue were measured. The right ovaries were used for histological and morphological tests. The obtained data were statistically analyzed by SPSS software using ANOVA and Tukey follow-up studies. Results showed that in the CP group a significant decrease was observed in ovarian follicles, the number of corpus luteum, levels of TAC, SOD and sex hormones; while, there was a significant increase in the number of atretic follicles and mast cells and level of MDA compared to control group. Administration of Cr along with CP caused a significant ameliorative effect on the studied parameters. In conclusion, the Cr could significantly decrease the side effects caused by CP chemotherapy in mice ovarian tissue.

Titanium dioxide particles (TiO2) as the second most widely used materials in consumer products are composed of nano-sized (100 nm) particles (FPs). Toxicological studies on animals have shown that TiO2 NPs exposure can cross the blood-testis barrier and accumulate in the testis resulting in testicular tissue damage and reduction of sperm count and motility. However, there is no information on the toxic effects of TiO2 FPs on male reproductive fertility. Twenty-four adult male mice were randomly divided into three groups including control, TiO2 NPs, and TiO2 FPs (150 mg kg-1 per day). After intragastric administration for 35 days, testicular tissue alterations (seminiferous tubule diameter and germinal epithelial height), sperm parameters (count, motility, viability, morphology, and DNA quality), in vitro fertilization potential, oxidative stress assays such as malondialdehyde (MDA) content, level of glutathione (GSH) and activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx) in testicular tissue were investigated. The results showed that both sizes of TiO2 caused pathologic changes in the testis and significantly increased MDA level and decreased GSH levels and activities of SOD and GPx in testicular tissue. Moreover, the administration of both sizes of TiO2 significantly decreased all of the sperm parameters and in vitro fertility (fertilization rate and pre-implantation embryos development) compared to control. Administration of TiO2 FPs similar to TiO2 NPs through inducing damages to testis led to a marked reduction in sperm quality, in vitro fertilization, and embryos development in male mice.

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.

Busulfan is an alkylating agent affects ovarian follicles growth by oxidative stress induction. Satureja khuzestanica has antioxidant effects. The aim of this study was to examine whether S. khuzestanica essential oil (SKEO) exhibits protective effects on busulfan-induced ovarian failure. Eighty-four adult female mice were divided into six groups including dimethyl sulfoxide (control), SKEO 225.00 mg kg-1 (orally), busulfan 3.00 mg kg-1 (orally), busulfan 36.00 mg kg-1 (intraperitoneally), busulfan 3.00 mg kg-1 and SKEO and busulfan 36.00 mg kg-1 and SKEO. After 28 days, the mice were euthanized and oocytes were removed for in vitro fertilization (IVF) rate evaluation. Oocyte quantity and quality, fertilization rate and pre-implantation embryo development were daily examined with a stereo microscope in a period of 120 hr. Serum levels of estradiol and progesterone were also evaluated. Busulfan caused significant decreases in oocyte number and quality, fertilization rate, pre-implantation embryo development and embryo quality. The SKEO significantly decreased the adverse effects of busulfan. The present study indicated that SKEO can protect female fertility potential against busulfan induced damages.

The aim of the present study was to assess the protective effect of ethyl pyruvate (EP) on sperm quality parameters, testosterone level and malondialdehyde (MDA) in phenylhydrazine (PHZ) treated mice. For this purpose, 32 NMRI mice with the age range of 8 to 10 weeks, weight average 26.0 ± 2.0 g, were randomly divided into four equal groups. The control group (1) received normal saline (0. 1 mL per day) by intraperitoneal injection (IP). Group 2 (PHZ group) was treated with initial dose of PHZ (8 mg 100 g-1, IP) followed by 6 mg 100 g-1 , IP every 48 hr. Group 3, (Group PHZ+EP) received PHZ (according to the previous prescription) with EP (40 mg kg-1, daily, IP). Ethyl pyruvate group (4) received only EP (40 mg kg-1, daily, IP). Treatment period was 35 days. After euthanasia, sperms from caudal region of epididymis were collected and the total mean sperm count, sperm viability, motility and morphology were determined. Testis tissue MDA and serum testosterone levels of all experimental groups were also evaluated. A considerable reduction in mean percentage of number, natural morphology of sperm, sperm motility and viability and serum testosterone concentration besides DNA injury increment among mice treating with PHZ in comparison with control group were observed. However, in PHZ+EP group the above mentioned parameters were improved. This study showed that PHZ caused induction of toxicity on sperm parameters and reduction of testosterone as well as the increment of MDA level and EP as an antioxidant could reduce destructive effects of PHZ on sperm parameters, testosterone level and lipid peroxidation.

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.

Cyclophosphamide (CP) is one of the anti-neoplastic drugs. Despite its numerous clinical applications, it has devastating effects on the testicles and declines the sperm quality in treated patients. This study was aimed to investigate the protective effect of crocin in improving the toxicity induced by CP in reproductive system. In this study, 24 male adult mice (6 to 8 weeks) were randomly divided into three groups, control group received normal saline (0.1 mL, IP, daily), the CP group received CP (15 mg kg-1, IP, weekly) and the CP + crocin group received CP along with crocin (200 mg kg-1, IP, daily). After 35 days of treatment, animals were sacrificed. The samples of epididymis in human tubal fluid medium incubated for 30 min in 5% CO2 for flotation of sperm. Sperm were obtained from caudal epididymis using dissecting method. Then, the parameters of sperm quality including sperm count, motility, viability, DNA damage, nuclear maturation, and sperm morphology were evaluated. In CP group, the sperm count, motility, viability, nuclear maturation and sperm morphology were significantly decreased compared to control group (p < 0.05) and in the CP + crocin group all of these parameters significantly increased compared to CP group (p < 0.05). The percentage of sperm with DNA damage in the CP group significantly increased compared to other groups (p < 0.05). The results of this study indicated that the crocin was able to suppress free radicals and enhance the quality of sperm in CP treated animals.

This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE) and vitamin E (Vit E) on sperm quality parameters in the methotrexate (MTX)-treated mice. Forty-eight young adult male mice (8-12 weeks) were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg-1, ip, once weekly), MTX + CMFE (250 mg kg-1), MTX + CMFE (500 mg kg-1), MTX + CMFE (1000 mg kg-1), and MTX + Vit E (100 IU kg-1, po) for 35 consecutive days. On day 35, after euthanasia the epididymal sperms were isolated. Then the total mean sperm count, sperm viability and motility were determined. The total antioxidant capacity (TAOC) of all experimental groups were also evaluated. The MTX-treated animals showed a significant changes in all parameters of sperm quality assessment compared to the control group. Both Vit E and CMFE were able to protect from MTX-induced effects on sperm maturity and DNA damage. Co-administration of MTX and CMFE and/or Vit E resulted in protection from MTX-reduced TAOC. In conclusion, these data suggested that MTX administration could adversely affect the sperm quality. Moreover, the protective effect of Vit E and CMFE on MTX-induced sperm toxicity was also documented.
