Abstract: 

Background: Wide range of disorders ranging from genetic disorders to coital difficulties can influence male fertility. In this regard, genetic factors are highlighted as the most frequent, contributed to 10-15%, of male infertility causes.Objective: To investigate the influence of genetic abnormalities on semen quality and reproductive hormone levels of infertile men from Northeast China.Materials and Methods: 2034 infertile men including 691 patients with abnormal sperm parameters were investigated retrospectively. Semen analysis was performed according to the World Health Organization guidelines. Y chromosome micro deletions were detected by polymerase chain reaction assays. Chromosome analysis was performed using G-banding.Results: The incidence of abnormal chromosomal karyotype in the patients with abnormal sperm parameters was 12.01% (83.691). The most frequent cause was Klinefelter's syndrome 37.35% (31.83). As the same as chromosomal abnormalities group, the volumes of testes (p=0.000 and 0.000, respectively) and the levels of testosterone (T) (p=0.000), and testosterone/ luteinizing hormone (T/LH) (p=0.000) of patients with Y chromosome micro deletions were significantly lower than those of fertile group. In addition, the levels of follicle-stimulating hormone (FSH) (p=0.000), and luteinizing hormone (LH) (p=0.000) were significantly higher in patients with Y chromosome micro deletions than those in the fertile group. Translocation abnormalities displayed slight effect on sperm motility.Conclusion: Y chromosome micro deletions and sex chromosome disorders particularly Klinefelter’s (47, XXY), have severe adverse influence on normal hormone levels, testicular volume and sperm count, whereas translocation abnormalities may inversely correlate with sperm motility.

Abstract: 

Background: Oxidative stress in teratozoospermic semen samples caused poor assisted reproductive techniques (ART) outcomes. Among antioxidants, ascorbic acid is a naturally occurring free radical scavenger and as such its presence assists various other mechanisms in decreasing numerous disruptive free radical processes.Objective: The main goal of this study was to evaluate potential protective effects of ascorbic acid supplementation during in vitro culture of teratozoospermic specimens.Materials and Methods: Teratozoospermic semen samples that collected from 15 volunteers were processed, centrifuged and incubated at 37PoPC until sperm swimmed-up. Supernatant was divided into four groups and incubated at 37PoPC for one hour under different experimental conditions: Control, 10 mm A23187, 600mm ascorbic acid and 10 mm A23187+600 mm ascorbic acid. After incubation sperm motility, viability, acrosome reaction, DNA damage and malondialdehyde levels were evaluated.Results: Our results indicated that after one hour incubation, ascorbic acid significantly reduced malondialdehyde level in ascorbic acid group (1.4±0.11 nmol/ml) compared to control group (1.58±0.13 nmol/ml) (p<0.001). At the end of incubation, progressive motility and viability in ascorbic acid group (64.5±8.8% and 80.3±6.4%, respectively) were significantly (p<0.05 and p<0.001, respectively) higher than the control group (54.5±6.8% and 70.9±7.3%, respectively). A23187 significantly (p<0.0001) increased acrosome reaction in A23187 group (37.3±5.6%) compared to control group (8.5±3.2%) and this effect of A23187 attenuated by ascorbic acid in ascorbic acid+A23187 group (17.2±4.4%). DNA fragmentation in ascorbic acid group (20±4.1%) was significantly (p<0.001) lower than controls (28.9±4.6%).Conclusion: In vitro ascorbic acid supplementation during teratozoospermic semen processing for ART could protect teratozoospermic specimens against oxidative stress, and it could improve ART outcome.

Abstract: 

Background: Based on classical two-cell, two-gonadotropin theory, in the follicle, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) put on their main effects on the granulosa and theca cells. LH is essential for androgens production. Androgens are used for estradiol production by granulosa cells. Profound suppression of LH concentrations in some normogonadotropic patients can cause several adverse effects.Objective: The main clinical purpose of this study was that normoresponder women treated with controlled ovarian super ovulation for IVF or ICSI may benefit from co-administration of rLH.Materials and Methods: 40 patients who were candidates for assisted reproductive technology (ART) were randomly selected. In all patients long luteal protocol was used for ovulation induction. Patients were randomly divided into two groups: Group 1 (n=20) with standard long protocol (GnRH agonist) and r-FSH alone, Group 2 (n=20) with standard long protocol (GnRH agonist) and r-FSH with r-LH. Results were statistically analyzed and compared in two groups.Results: The number of retrieved oocytes, mature oocytes, cleaved embryos, transferred embryos, estradiol levels in Human chorionic gonadotropin (hCG) administration day, implantation rate and clinical pregnancy rate in group 2 were higher but not significantly different.Conclusion: Administration of rLH in late follicular phase had no beneficial effect on outcomes in young women with mean age of 31 years. Maybe a greater sample size should be used to see the effects more accurately; also it is possible that rLH will be useful in older patients.

Abstract: 

Background: In recent years, the study of birth intervals has been a main determinant of the levels of fertility in the populations, as it is associated with rates of fertility and population growth.Objective: The purpose of this study was to firstly apply survival analysis for modeling of first birth interval and secondly to explore its determinants.Materials and Methods: In a cross sectional study, the fertility history of 858 women was collected in rural areas of Shiraz (southern Iran) in 2008. We used the survival analysis such as cox regression and alternative parametric models to evaluate the prognostic factors of first birth interval.Results: Among the explanatory variables of interest, age at marriage, level of women's education, and menstrual status had highly significant effects on the duration of birth interval after marriage (p<0.01).Conclusion: It is concluded that the suitable parametric models would be a useful tool for fitting to first birth interval, the fact that has been less paid attention to in researches.

Abstract: 

Background: Infertility is a major life event that brings about social and psychological problems. The type and rate these problems in the context of socio-cultural of different geographical areas and sex of people is different.Objective: The aim of this qualitative study was to explain the psychological consequences of infertility in Iranian infertile women seeking treatment.Materials and Methods: This qualitative study was done using qualitative content analysis on 25 women affected by primary and secondary infertility with no surviving children in 2012. They were purposefully selected with maximum sample variation from a large Fertility Health Research Center in Tehran, Iran. Data were collected using 32 semi-structured interviews and analyzed by the conventional content analysis method.Results: The findings of this study include four main themes: 1. Cognitive reactions of infertility (mental engagement; psychological turmoil). 2. Cognitive reactions to therapy process (psychological turmoil; being difficult to control in some situations; reduced self-esteem; feelings of failure). 3. Emotional-affective reactions of infertility (fear, anxiety and worry; loneliness and guilt; grief and depression; regret). 4. Emotional-affective reactions to therapy process (fear, anxiety and worry; fatigue and helplessness; grief and depression; hopelessness).Conclusion: This study revealed that Iranian infertile women seeking treatment face several psychological-emotional problems with devastating effects on the mental health and well-being of the infertile individuals and couples, while the infertility is often treated as a biomedical issue in Iranian context with less attention on the mental-emotional, social and cultural aspects.

Abstract: 

Background: Nano-particles are extensively employed in most industries. Several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. However, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices.Objective: Investigation of the effects of silver nano-particles on sperm parameters, sex hormones and Leydig cells in rat as an experimental model.Materials and Methods: In this experimental study, 75 male prepubertal Wistar rats were categorized in five groups including control group and 4 experimental groups (n=15 in each group). The rats in the experimental groups were fed silver nano-particles (60 nm in dimension) with concentrations of 25, 50, 100, and 200 mg/kg/day. After 45 days (about one duration of spermatogenesis in rat), samples of blood were taken from the rats for testosterone, leuteinizing hormone (LH), and follicle stimulating hormone (FSH) assessments. Afterwards, the epididymis and the testis of each rat were dissected for analyzing sperm parameters and Leydig cells.Results: The results demonstrated a statistically significant reduction in number of Leydig cells in experimental groups compared to control one. In addition, the data showed a reduction in testosterone and a rise in LH level which was more obvious in high doses (p<0.05); however, FSH level showed a reduction but it was not statistically significant. A significant decrease was also found in sperm motility and normal sperm morphology in the experimental groups compared to the control one.Conclusion: Our results demonstrated that silver nano-particles, in addition to interruption in functions of sex hormones, can diminish the number of Leydig cells and sperm parameter indices. It should be noted that the effects of nano-particles on reproductive indices are dose-dependent.

Abstract: 

Background: Preterm labor is the leading cause of infant morbidity and mortality so it may be necessary to administer tocolytics for treatment of it.Objective: The aim of this study was to compare the efficacy and safety of magnesium sulfate and nifedipine in the management of preterm labor.Materials and Methods: 100 women with documented preterm labor were randomly assigned to receive magnesium sulfate (n=50) and nifedipine (n=50) as tocolytic therapy. Before tocolysis, patient did not receive any sedation. After tocolysis, if patient continued to have contractions, they received other tocolytic agents. The main outcome variables examined were days gain in utero, success rate and side effects.Results: Both drugs were equally effective in prevention of labor and delaying delivery >7 days, 56% vs. 64% in the nifedipine and magnesium sulfate groups, and the days gain in utero was no statistically different in two groups. 6% of nifedipine group and 2% of magnesium sulfate group required drug discontinuation due to severe symptoms. There were also no significant differences in maternal characteristics between two groups. The total success rate and side effects were similar in two groups.Conclusion: Oral nifedipine could be a suitable alternative for magnesium sulfate with the same efficacy and side effects in the management of preterm labor.

Abstract: 

Background: Cytomegalovirus (CMV) is a prevalent infection in humans. Recent studies have shown the role of CMV infection in male infertility disorder.Aim: Here we aimed to study the role of CMV infection in men with idiopathic infertility.Materials and Methods: We performed a case-control study of CMV serology in 200 patients attending male infertility clinic of a university hospital. There were 154 men diagnosed with infertility and 46 men without infertility. The patients were asked to donate their sperm, blood, and urine. The presence of CMV infection was studied using quantitative polymerase chain reaction.Results: CMV infection was present in 25 of all the studied participants. Controls had a higher sperm count and sperm motility and sperm morphology compared to patients. There were no significant differences in the studied variables between those with and without CMV infection, nor in patients, neither in controls. Sperm morphology was negatively correlated with cigarette smoking (r=-0.15; p<0.03). Even though the prevalence of CMV infection was higher in patients with infertility in control and patient (5.46 vs. 20.154) respectively, this was not statistically significant.Conclusion: We did not show a significant role for CMV infection in male infertility. Based on the previous studies, it could be assumed that CMV infection is an important part of the male infertility and its treatment would improve the sperm quality, however this was not confirmed by the present study.

Abstract: 

Background: The incidence of ectopic pregnancy varies between 1.5-2% of all pregnancies. Bilateral tubal ectopic pregnancy is rare. It may occur in 1 per 200 000 pregnancies.Case: This is a case report of 25 year-old woman who underwent intra uterine insemination (IUI), because of tubal factor infertility (unilateral). On the 30PthP day after the IUI she complained from pelvic pain and vaginal bleeding. Pelvic ultrasound showed bilateral tubal ectopic pregnancy with fluid in Douglas Pouch and empty uterine cavity. Exploratory laparotomy, left salpingectomy, and right salpingostomy were performed on the same day of admission.Conclusion: The above case suggests that cases presenting with infertility and ectopic pregnancy should be followed very closely with b-hCG and or Trans Vaginal Sonography (TVS) to exclude double ectopic. So, as in this case, early diagnosis is essential for prevention of maternal morbidity and mortality.
