Abstract
Background: Varicocele is recognized as the most common cause of male factor infertility and is found in 15% of the general population. This prevalence increases to 35% in men presenting with primary infertility and between 70 to 80% in men presenting with secondary infertility. The effect of varicocele on Leydig cell function and testosterone production has been always a question. In this study we examined the effect of varicocelectomy on serum testosterone. Methods: This research protocol was approved by the institutional review board at Royan Institute in infertility department and also this study has been done in Royan Institute (Tehran, Iran) during one year since September 2012 till October 2013. In this cross-sectional study, Serum levels of total testosterone in 79 men with clinical varicocele and in 70 fertile men who served as a control group were compared. Men aged 23–46 years with clinically palpable varicoceles as determined by physical examination were studied. Three to 6 months, testosterone levels were measured again after varicocelectomy, then testosterone levels were compared before and after varicocelectomy. Results: The mean of serum testosterone levels before surgery in infertile men with varicocele and fertile men were 590(230) vs. 583(237) ng/dl respectively. No statistically significant changes were noted in serum testosterone levels for any groups. Three month after varicocelectomy mean serum testosterone levels were significantly increased in infertile men with varicocele compared with preoperative levels from 590 (230) to 663 (242) ng/dl (P=0.009). Also the testis volume of patients were examined, which were divided into two groups included the men with testis volume less than 16 ml (<16) and more than 16 ml (≥16). Conclusion: In infertile men affected with clinical varicocele, varicocelectomy seems to have caused positive impact on the level of serum testosterone increase. It is thought that positive effect is probably caused by improvement of the Leydig cell functions which induce the increase of serum testosterone level.

Abstract

Background: Multiple Sclerosis (MS) is a neurodegenerative disease of the central nervous system (CNS). The hippocampus is a vital center for learning and memory it is extremely vulnerable to neurodegenerative diseases. The male hormones could be neuroprotective for the CNS. The current study is an attempt to investigate the effect of testosterone on learning and spatial memory following the demyelination of CA1 area by the injection of ethidium bromide in the rats' hippocampus. Methods: This experimental study has been conducted on healthy rats in the faculty of science of the Urmia University from September 2013 to February 2015. For demyelination in all previously gonadectomized healthy rats, 3µl ethidium bromide was injected into the CA1 area of rats by stereotaxic surgery. In addition, the treatment groups received 1µl testosterone (6µg/µl) during a 20-day timeframe on a daily basis after demyelination by the ethidium bromide. The control groups had no drug injection. The process of the learning and spatial memory of the rats were closely monitored by the radial Maze. The demyelination and remyelination in the hippocampus were checked by the myelin-specific coloring (Luxol fast blue and Cresyl violet). Results: The histological results suggest that the testosterone is capable of minimizing the destructive impacts of ethidium bromide in the treatment group as well as enhancing the remyelination process. In the group treated by testosterone, the percentage of the pyknotic cells 20 days after demyelination induction, represented a significant reduction compared to that of ethidium bromide group (P=0.008). The behavioral studies analyses show that the amount of the food finding time in those groups received ethidium bromide was significantly longer than those of the control groups (P=0.001). Furthermore, the application of the testosterone in the treatment groups reduced the extent of demyelination while the memory impairment induced by the ethidium bromide was significantly improved (P=0.001). Conclusion: Testosterone can act as a neuroprotective factor that reduces the extent of demyelination and the number of pyknotic cells. It also may improve the learning and memory impairment induced by ethidium bromide.

Abstract
Background: Polycystic ovary syndrome (PCOS) is an endocrine disorder and one of the main reasons of infertility in women. PCOS causes many symptoms in women, one of the most important of them is ovulation failure. It affects the women at the age of fertility. Many factors are detected to exacerbate PCOS including insulin, anti-Mullerian hormone, obesity and androgen. The aim of this study was to evaluate endocrine and metabolic factors and its relation with obesity in patients with polycystic ovary syndrome in exacerbation of disease.
Methods: This cross-sectional study was carried out at the Caucasus Infertility Treatment Center of Ardabil from July 2015 to March 2016 and on 321 patients with polycystic ovary syndrome. Blood samples were investigated to measure serum levels of fasting insulin, dehydroepiandrosterone sulfate (DHEAS), 17OHP, fasting blood sugar, sex hormone binding globulin (SHBG), anti-Mullerian hormone, vitamin D, total testosterone, free testosterone, prolactin, FSH, LH and TSH. Also, body mass index (BMI), duration of infertility and age were measured. BMI was evaluated to measure the obesity of patients.
Results: We were able to demonstrate significantly high level of total testosterone and fasting insulin in PCOS women by having weight gain (P< 0.05). Response to drug was significantly increased with reduced weight of these patients (P= 0.02). The level of fasting blood sugar (P= 0.01) and anti-Mullerian hormone (P< 0.05) were increased significantly with access in PCOS. On the other hand, our data showed that duration of infertility was increased by growing the age of patients (P< 0.05).
Conclusion: Insulin resistance, obesity, hyperandrogenism and metabolic syndrome are very important factors in pathogenesis of PCOS. These factors could affect the fertility of women by effecting the reproductive processes. Therefore, it is better in the patients who are older, treatment strategies further underline on reduce these factors (insulin resistance, obesity and hyperandrogenism) to prevent disease progression and increase duration of infertility.
