Background: In vitro maturation (IVM) of oocytes reduces the costs and averts the side-effects of gonadotropin stimulation for in vitro fertilization (IVF). Reliable IVM is an intellectual, scientific and clinical challenge with a number of potential applications.
Objective: The effect of hCG was evaluated on the timing and regulation of in vitro ovulation for the Syrian mice oocytes in the presence and absence of FSH. 
Materials and Methods: Preantral follicles, isolated from the ovaries of 6 weeks-old mice, were cultured in TCM-199 medium. The effect of 10-200 mIU/ml FSH and 1.5 IU/ml hCG was seen on the follicle maturation, as well as the changes in ovulation capacity of enclosed oocytes, after the incubation period of 6 days at 37 °C, 92% humidity and 5% CO2 in air.
Results: 100 mIU/ml FSH showed increased follicle diameter, survival, germinal vesicle breakdown (GVBD) and oocyte maturation rates (p<0.0001). Significantly higher number of follicles showed cumulus attachment when ovulation started within 16-24 hours post hCG (97% and 80% respectively; p<0.0001) as compared to the cultures without hCG or when the ovulation time increased from 24 hours post hCG. Combination of FSH and hCG showed 97% (p<0.0001) ovulation as compared to that seen for FSH-containing medium only (81%) or control (10%).
Conclusion: The combined administration of 1.5 IU/ml hCG and 100 mIU/ml FSH induces the in vitro follicle maturation, ovulation capacity and proper timing of mice oocytes.

Background: Considerable attention is focused on effects of electromagnetic field (EMF) and its increasing use in everyday life. Appliances and various equipments are sources of electromagnetic fields with a wide-range of technical characteristics.
Objective: In this study we investigated the effect of EMF (50 Hz, 0.5 mT) on epididymis and deferens duct in mice.
Materials and Methods: 30 BALB/C mice were selected and divided into three groups (control, sham and experimental). While control and sham groups were not exposed to EMF, the experimental group was exposed to EMF (50 Hz, 0.5 mT) 4 hours a day, 6 days per week and for 2 months. At the end of 2 months, the mice were sacrificed, dissected and samples from epididymis and vas deferens in all groups were taken and processed for light microscopic studies. 40 microscopic fields from each group were randomly selected. The diameters and the height of epithelial cells of epididymis and deferens duct in 3 groups were measured and compared using statistical methods.
Results: The data showed that the mean diameter of epididymis and deferens duct in EMF group was significantly decreased compared to the control group (p=0.001). The height of epithelial cells in epididymis and deferens duct in EMF group was considerably reduced compared to the control and sham groups (p=0.001). In addition, the weight of testes in EMF group was significantly decreased compared to the control and sham groups (p&lt;0.007). Conclusion: It could be concluded that the exposure to EMF leads to detrimental effects on male reproductive system in mice as seen by a decrease in diameter of reproductive ducts, the height of epithelial cells and weight of testes.

Background: Male infertility accounts for 30-50% of all infertilities among couples. Iranian traditional medicine (ITM) stressed the importance of nutrition in the prevention and treatment of male infertility. Many Iranian traditional physicians have described the traits of specific foods for prevention and treatment of male infertility.
Objective: To explore the principles and roles of foods recommended by ITM scientists in prevention and treatment of male infertility as well as enlisting all the recommended foods for treating this problem addressed through the ITM original resources written between 815 and 1901.
Materials and Methods: In this review study specific data related to the subject among all referral ITM texts was extracted firstly, and then the collected data were analyzed using inductive content analysis.
Results: The analysis of data revealed that foods that enhance sexual performance must have 3 properties; they should be warm in nature, very nutritious, and flatulent. Foods that are warm in nature and nutritious affect the quality and quantity of semen. A food having the third trait of being flatulent is required to complete sexual performance by creating an erection. Foods with only one of these traits must be consumed with another food that has the other trait. This study also provided a list of foods that can enhance the quality and increase the quantity of semen.
Conclusion: Foods that can enhance sexual performance and the quality and quantity of semen can be recommended to male patients who suffer from infertility in medical centers.

Background: The relation of placental gross morphology and the outcome of pregnancies complicated with diabetes mellitus in comparison with healthy pregnancies is not known. Identifying significant differences in pregnancy outcomes in Gestational Diabetes Mellitus (GDM) and healthy pregnancies by the means of morphologic measurements can induce the use of antenatal ultrasonography of placental parameters to predict pregnancy outcomes.
Objective: This study aimed to evaluate the relationship between placental morphological parameters of the placenta and cord and the outcomes of pregnancies complicated with diabetes mellitus.
Materials and Methods: In this case-control study, which was conducted at two referral perinatology center in Tehran between March 2017 and November 2018, 60 pregnant women with GDM who were controlled with either diet or insulin as the case group and 60 pregnant women without GDM as the control group were enrolled. The study population were selected from patients who had their prenatal care and delivery in Mahdieh and Shohadaye Tajrish Hospital. The data was collected by taking sickness history, using data from patients files, and measuring of placental and newborn parameters after delivery. GDM was diagnosed either by 75 gr or 100 gr oral glucose tolerance tests. Placenta parameters, umbilical cord features, and newborn outcomes were compared between the two groups.
Results: Placental weight, diameter, number of lobes, thickness, placental weight to-newborn weight ratio, place of umbilical cord insertion, length, coiling, and diameter of the umbilical cord are similar in two groups. Newborn weight, NICU admission, ABG, and Apgar score are also the same in well-controlled GDM pregnancy and pregnancy without GDM.
Conclusion: Good controlled GDM causes no difference in placental gross morphology and pregnancy outcome compared to a healthy pregnancy.
