Preeclampsia is an important pregnancy disorder with serious maternal and fetal complications which its etiology has not been completely understood yet. Early diagnosis and management of disease could reduce its potential side effects. The vascular endothelial growth factor (VEGF) family including VEGF-A is the most potent endothelial growth factor which induces angiogenesis and endothelial cell proliferation and has basic role in vasculogenesis. VEGF and its tyrosine kinase receptors (Flt1 and KDR) are major factors for fetal and placental angiogenic development. Finding mechanisms involved in expression of angiogenic factors may lead to new prognostic and therapeutic points in management of preeclampsia. Recent researches, has shown capability of some anti-angiogenic factors as potential candidate to be used as early predictors for preeclampsia. Soluble fms-like tyrosin kinase-1 (sFlt1) is a truncated splice variant of the membrane-bound VEGF receptor Flt1, that is produced by the placenta and it can bind to angiogenic growth factors and neutraliz, their effects. It is also observed that the ratio of sFlt1 to placental growth factor is valuable as prognostic marker. In this review, VEGF family member’s role in angiogenesis is evaluated as biomarkers to be used for prediction of preeclampsia.

The prevalence of polycystic ovarian syndrome (PCOS) particularly is increased in adolescents. Very few longitudinal follow-up for assessment of ovarian reserve in women of late reproductive age with previously confirmed PCOS have been conducted, especially after its diagnosis and treatment in adolescence.

The aim of the present study was to compare of the ovarian reserve of the women of late reproductive age by the method of treatment of PCOS in adolescence.

This cross sectional study in an unselected population was conducted from January to June 2014. A total of 123 women of late reproductive age were included. They had been diagnosed with PCOS between 1984 and 1990 when they were 13-18 yr. From these, first group of the study was consisted of 67 participants who underwent conservative treatment with antiandrogens and combined oral contraceptives and second group of the study was consisted of 56 participants after surgery (34-bilateral ovarian drilling and 22- ovarian wedge resection). At the time of investigation patients were 35-45 yr. The participants were collected via analysis of histories at primary diagnosis of PCOS in adolescence and at the time of the investigation analyses of reproductive hormones were conducted. Data were compared between the groups.

After conservative treatment PCOS women had higher levels of anti- mullerian hormone and lower follicle-stimulating hormone levels (p=0.02 and p=0.04, respectively). The number of antral follicles and mean ovarian volume were significantly greater also, than in women who underwent surgical treatment (p=0.03 and p=0.04, respectively).

Our data suggest that PCOS patients who underwent conservative treatment have the better ovarian reserve than women who underwent surgical treatment of PCOS in adolescence.

Differential diagnosis between complete hydatidiform mole, partial hydatidiform mole and hydropic abortion, known as hydropic placentas is still a challenge for pathologists but it is very important for patient management.

We analyzed the nuclear DNA content of various types of hydropic placentas by flowcytometry.

DNA ploidy analysis was performed in 20 non-molar (hydropic and non-hydropic spontaneous abortions) and 20 molar (complete and partial moles), formalin-fixed, paraffin-embedded tissue samples by flow cytometry. The criteria for selection were based on the histopathologic diagnosis.

Of 10 cases histologically diagnosed as complete hydatiform mole, 9 cases yielded diploid histograms, and 1 case was tetraploid. Of 10 partial hydatidiform moles, 8 were triploid and 2 were diploid. All of 20 cases diagnosed as spontaneous abortions (hydropic and non-hydropic) yielded diploid histograms.

These findings signify the importance of the combined use of conventional histology and ploidy analysis in the differential diagnosis of complete hydatidiform mole, partial hydatidiform mole and hydropic abortion.

One of the problems that addicts suffer from is decreased libido. Erectile dysfunction has been reported in men using opioids for treatment of heroin addiction.

The study was performed to investigate the effects of morphine and detoxification with methadone as causes of sexual dysfunction in addiction.Methods and

A total of 40 adult male rats (Wistar) were used. Animals were divided in to 4 groups. Control groups received saline for 30 days. Other 2 groups received 10 mg/kg morphine on day 1 and the morphine doses increased daily by 2 mg/kg increments per day until in day 30 a maximum of 68 mg/kg twice daily was achieved. Withdrawal syndrome sings were evaluated. At the end of period, one group of 2 morphine dependent groups was treated with methadone during 14 days. Animals in group 4 (saline solution+ methadone) received saline for 30 consecutive days and then detoxified with methadone during 14 days. Partial weights of seminal vesicles, testes, prostates, seminal vesicles content, concentrations of luteinizing hormone, follicle stimulating hormone, and testosterone in serum were determined.

In the dependent group serum levels of testosterone (p<0.001), folicle stimulating hormone (p=0.0097) and luteinizing hormone (p=0.0031) as well as the weights of testes (p=0.0051), partial weights of prostates, seminal vesicles and seminal vesicles contents (p<0.001) were reduced as compared with control group. In the morphine dependent animals detoxified with methadone, testosterone concentrations and seminal vesicles contents remained lower than levels in the control group (p<0.001).

The results suggest that morphine dependence may impair the reproductive function in male rats.

Ischemia reperfusion (IR) is the main pathology of torsion of testis and it is a common urologic emergency. There is some evidence that shows oxytocin (OT) plays role in ischemia reperfusion.

To evaluate this hypothesis that OT can decrease germ cell apoptotic index in testis under acute ischemia reperfusion in a rat model.

20 adult rats were randomly divided into four groups: Control, IR, OT and IR+ OT (OTA). Testicular ischemia was achieved by 720° torsion of the left testis for 2 hr. Then, torsion was removed and reperfusion was performed. Immediately after induction of reperfusion 0.03 µg/kg OT were administered intraperitoneally to the IR+ OT. Three hours after surgery left testis was removed and evaluations were made by Johnson’s score, ELISA, immunohistochemistry and histomorphometry for study of maturity of spermatogenesis, endocrine profiles, apoptosis and quantitative studies, respectively.

The results showed in addition tissue edema and congestion, a significant reduced in Johnson’s score were detected in IR group in comparison with controls (p=0.01), and apoptotic index increased significantly (p=0.001). Administration of OT in OT+IR group, increased Johnson’s score but it was not statistically significant. Germinal epithelium thickness was increased significantly (p=0.03), although apoptotic index decreased significantly in comparison with the IR group (p=0.04). However there was not significant difference in serum levels of testosterone, FSH and LH in none of groups (p=0.07).

These results suggested that OT can decrease apoptotic index and improves complication of acute ischemic reperfusion in testis in a rat model.

One of the affecting factors in disturbance process of spermatogenesis is chemotherapeutic-induced oxidative stress resulted from cyclophosphamide (CP) treatment which leads to diminished sperm quality via interference in spermatogenesis process.

This study was conducted to investigate the effects of ethyl pyruvate (EP) in reducing the CP-induced side effects on reproductive system.

24 mature male mice were randomly divided into 3 equal groups and were undergone therapy for 35 days. Control group received normal saline (0.1 ml/day, IP). CP group were injected CP (15 mg/kg/week, IP) and CP+EP group received EP (40 mg/kg/day, IP) as well as CP. In the end of the treatment period, the mice were euthanized by cervical dislocation. Then, the epididymis was incubated with CO2 in a human tubal fluid medium (1 ml) for half an hour in order to float sperm. Then, the number, motility, viability (eosin-nigrosin staining), DNA breakage (acridine orange staining), nucleus maturity, and sperm morphology (aniline blue staining) were analyzed.

The average (15.87±1.28), motility (35.77±2.75), viability (40±3.03), nucleus maturity (36±2.79) and sperm morphology (61.75±0.85) were decreased significantly in CP group in comparison with control and EP groups, whereas EP caused significant increase of these parameters. Also, the percentage of DNA damage was increased significantly in CP group (41.75±3.75) in comparison with control (2±0.71) and EP groups (22.5±4.13).

The results of this study revealed ameliorating effects of EP on sperm quality of CP treated animals.

Genital tuberculosis (TB) is an important cause of infertility in the developing countries, where hysterosalpingography (HSG) remains an initial diagnostic procedure in the evaluation of tubal and peritoneal factors leading to infertility.

The aim of this study was to determine the HSG findings of genital TB in infertile women.

We retrospectively reviewed HSG findings in 20 women with genital tuberculosis. HSG was performed in these women as part of infertility work up over 5 years. The other diagnostic procedures used included endometrial curettage and biopsy, histological examination, culture, laparoscopy, hysteroscopy and polymerase chain reaction.

The mean age of the participants was 30.5±8 years. All women had clinical history of infertility for at least 4 years. Women presented with pelvic abdominal pain (30-35%) and menstrual disturbances (20-25%). Reviewing 20 cases of female genital TB were encountered various presentations on HSG.

HSG is an invaluable procedure in suggesting the diagnosis of genital TB in patients being investigated for infertility.

Androgens play critical role in secondary sexual and male gonads differentiations such as spermatogenesis, via androgen receptor. The human androgen receptor (AR) encoding gene contains two regions with three nucleotide polymorphic repeats (CAG and GGN) in the first exon. Unlike the CAG repeats, the GGN has been less studied because of technical difficulties, so the functional role of these polymorphic repeats is still unclear.

The goal of this study was to investigate any relationship between GGN repeat length in the first exon of AR gene and idiopathic male infertility in southwest of Iran.

This is the first study on GGN repeat of AR gene in infertile male in Khuzestan, Iran. We used polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis to categorize GGN repeat lengths in 72 infertile and 72 fertile men. Afterwards we sequenced the PCR products to determine the exact length of GGN repeat in each category. Our samples included 36 azoospermic and 36 oligozoospermic men as cases and 72 fertile men as control group.

We found that the numbers of repeats in the cases range from 18 to 25, while in the controls this range is from 20 to 28. The results showed a significant relation between the length of GGN repeat and fertility (p=0.015). The most frequent alleles were alleles with 24 and 25 repeats respectively in case and control groups. On the other hand no significant differences were found between Arab and non-Arab cases by considering GGN repeat lengths (p=0.234).

Due to our results, there is a significant association between the presence of allele with 24 repeats and susceptibility to male infertility. Therefore this polymorphism should be considered in future studies to clarify etiology of disorders related to androgen receptor activity.

In vitro fertilization and embryo transfer (IVF-ET) is the best option for patients with hydrosalpinx. However, if hydrosalpinges is not pre-treated, the therapeutic outcomes of IVF-ET would be compromised.

This study aims to investigate the safety and effects of operative hysteroscopy in the treatment of patients with hydrosalpinx prior to IVF-ET, who were not indicated for laparotomy due to extensive pelvic adhesion.

The study analyses retrospectively data from 10 women with hydrosalpinx, who were unable to undergo laparotomy due to extensive pelvic adhesion and treated by operative hysteroscopy prior to IVF-ET, and was assessed the effects and safety of the procedure.

Postoperative Hystero-salpingography demonstrated complete tubal occlusion of the diseased side in all cases. Being applied with IVF-ET for fertility after their hysteroscopy operation, 5 out of 10 patients acquired clinical pregnancy.

Hysteroscopic tubal occlusion of the proximal part of the hydrosalpinx can effectively prevent the hydrops backflow to endometrial cavity and benefit subsequent implantation in the course of assisted reproduction without significant complications.
