Abstract

Background: The most frequent physical finding in infertile men is varicocele, in which one of the mechanisms that can affect seminal parameters is oxidative stress.
Objective: Our study aimed, for the first time, to compare the efficacy of recombinant human follicle-stimulating hormone (rhFSH), human chorionic gonadotropin (HCG) and human menopausal gonadotropin (HMG) on sperm parameters and fertility after varicocelectomy.
Materials and Methods: 113 infertile men with varicocele were divided into four groups. Group A received HCG 5000 IU weekly, group B received HMG 75 IU three times a week, group C received rhFSH 75 IU three times a week and group D received no medical treatment after varicocelectomy.
Results: After three months, in group A sperm morphology improved (p=0.007), causing a 32% pregnancy rate. In group B, sperm motility (p=0.023) and morphology (p=0.014) improved, causing a 57% pregnancy rate. In group C, all of the investigated semen parameters increased (p<0.05), causing a 62.5% pregnancy rate. Only rhFSH improved sperm concentrations to >20×106 mL (p=0.027). In group D, sperm morphology increased (p=0.038), but other parameters remained unchanged and no pregnancies occurred.
Conclusion: It can be concluded that drugs can reduce induction time for spermatogenesis and fertility in comparison with varicocelectomy alone. For these purposes, rhFSH is more effective than other drugs.

Abstract

Background: During the month of Ramadan, millions of Muslims abstain from food and drink daily from dawn to sunset and people actually experience repeated cycles of fasting and refeeding. Menstruation is a normal physiological process that its regularity is controlled by hypothalamic-pituitary-ovarian axis. Etiology of menstrual dysfunction includes weight loss, hypoleptinemia, abnormal eating behaviors, exercise, and psychological stressors.
Objective: To investigate the effects of Ramadan fasting on menstrual cycles.
Materials and Methods: This analytic cross-sectional study was performed on 80 female college students resident in a dormitory of Hamedan University of Medical Sciences. A questionnaire including demographic characteristics and menstrual calendar was filled by all participants. All analyses were performed using the statistical software SPSS for Windows version 11.5.
Results: We found 11.3%, 30%, and 16.3% of participates had abnormal menstrual pattern three months before, during and three months after Ramadan, respectively. In participates who fast more than 15 days, menstrual period had significantly more abnormality than participants who fast less than 15 days. Considering our results we demonstrated that menstrual abnormalities during Ramadan month reach to their peak and three months after Ramadan reduce but do not return to previous condition.
Conclusion: This study confirms that menstrual abnormalities including oligomenorrhea, polymenorrhea and hypermenorrhea increased during Ramadan especially in participates with more than 15 days of fasting.

Abstract

Embryo transfer and its related factors received little clinical attention and had been, until recently, the most inefficient step in in-vitro fertilization (IVF). Factors which appear to influence implantation rates are: contamination of the catheter tip with cervical bacteria, stimulation of uterine contractions during the procedure, the type of catheter, ultrasound guidance during the transfer, the position of the embryos in the uterine cavity and perhaps cervical mucus (1-4). Easy and atraumatic transfer is essential for successful implantation and the embryos need to be placed in the middle of the cavity, away from the fundus (5). The goal of trans-cervical embryo transfer is to non-traumatic deliver the embryo to an optimal intra uterine location for implantation. Cervical canal mucus may cover the catheter tip and it can be a source of bacterial contamination of uterine cavity. Therefore, aim of this study was evaluation of effect of removal of cervical mucus on clinical pregnancy rate. This study was carried out as a randomized controlled trial. Randomization was done for stratification of age, method of treatment and cause of infertility. A total of 120 women (18-35 years) with male factor infertility, was undergoing IVF cycles with long protocol, divided to two groups: 60 infertile women as cases (group A) that cervical mucus was aspirated and 60 women as controls (group B), without aspiration. In both groups scrub was done by normal saline. Aspiration of cervical mucus was performed by Mucat catheter just before embryo transfer in case group. Embryo transfer was done after 36 hours of puncture. Bed rest for all women after embryo transfer was 1 hours. Primary outcome and pregnancy defined as: positive βhCG 12 days after embryo transfer. The mean age of group A was 29.93±5.04 years, and in the group B was 29.03±4.5 years (p>0.05). The mean duration of infertility in group A was 7.6±5.6 years and in group B the mean duration of infertility was 5.5±3.2 years (p>0.05). The frequencies of previous IVF in group A and B was 38.3%, and 28.13% respectively (p>0.05, OR=1.64 in group A, OR=2.64 in group B). There was no significant difference between two groups in terms of number of transferred embryos statistically (p=0.06). The quality of transferred embryo in group A was as following: grade a 67.7%, grade b 16.7%, grade c 6.7%, and in group B was: grade a 85% and grade b 15%, and two groups were also no significantly different (p>0.05). Contact bleeding was happened in 1.7% of group A and 3.3% of group B. The rate of pregnancy (positive βhCG) in the group A was 11.7% (n=7), however, in the group B was 16.7% (n=10) and two groups had not significant difference statistically (p>0.05, OR=0.66). This study indicates that, removal of cervical mucus during embryo transfer (ET) has no positive effect on the pregnancy rate. However, according to some reports, removal of cervical mucus during ET had been postulated to increase the pregnancy and implantation rates by not interfering with embryo implantation (6). Some researchers suggested that, this is a time- consuming procedure that may increase the incidence of difficult transfers by removing the naturally lubricant mucus. In addition, any cervical manipulation at the time of embryo transfer may cause unwarranted uterine contraction. Several studies have shown a correlation between cervical mucus aspiration and increase pregnancy rates (4, 7). According to the study of Yazd University of Medical Sciences, cervical mucus aspiration with insulin syringe before embryo transfer can increase the pregnancy rate (8). According to some reports the presence of bacterial contamination of catheter tip during embryo is evidently limited and does not significantly affect the cycle outcomes (2). Several studies have shown that cervical mucus aspiration can decrease infection rate with E. coli, Mycoplasma, Uroplasma, Streptococcus B, D, Staphilococcus and increase implantation rate (9). In addition to cleaning cervical mucus, other interventions, such as drug prescription (ritodrine for example) also has no significant effect on pregnancy rate (10). Present study showed no positive correlation between this intervention and result of pregnancy outcome; however, total pregnancy rate in both groups was not high. Because of this procedure may increase the incidence of difficult transfer by removing the naturally lubricant mucus and may cause uterine contraction. In conclusion, the data presented in this study suggest that cervical area and uterus environment manipulation before embryo transfer is not recommended.

Abstract

Background: Infertility is considered as a major health care problem of different communities. The high prevalence of this issue doubled its importance. A significant proportion of infertility have been related to environmental conditions and also acquired risk factors. Different environmental conditions emphasized the need to study the different causes of infertility in each area.
Objective: The aim of this study was to determine the frequency causes of infertility in infertile couples.
Materials and Methods: In this cross sectional descriptive study 1200 infertile men and women that were referred to infertility clinic of Fatemieh Hospital during 2010 to 2011, were examined. This center is the only governmental center for infertility in Hamadan. Sampling was based on census method. Information about the patients was obtained from medical examinations and laboratory findings. To analyze the data, descriptive statistics such as frequencies and the mean were used.
Results: The prevalence of primary and secondary infertility was 69.5% and 30.5% respectively. Among the various causes of infertility women factors (88.6%) had the highest regard. In the causes of female infertility, menstrual disorders, diseases (obesity, thyroid diseases, and diabetes), ovulation dysfunction, uterine factor, fallopian tubes and cervical factor had the highest prevalence respectively. The causes of male infertility based on their frequency included semen fluid abnormalities, genetic factors, vascular abnormalities, and anti-spermatogenesis factors, respectively.
Conclusion: Etiology pattern of infertility in our study is similar with the many other patterns that have been reported by the World Health Organization. However, frequency of menstrual disorders is much higher than other studies that require further consideration.
