Abstract

Background: Gonadotropin releasing hormone conjugate (GnRH-BSA) raises antibodies against biologically active gonadotropin releasing hormone (GnRH) which affects body weight, gonadosomatic indices (GSI) and sperm quality in male mice.
Objective: The objective of this experimental investigation is to develop an effective and reliable hormonal immunocontraceptive vaccine to suppress spermatogenesis by using GnRH-BSA conjugate.
Materials and Methods: Forty sexually mature mice, Mus musculus were divided into two groups of twenty each. Group 1, served as control, while group 2 were immunized at monthly intervals for four times against GnRH with a GnRH-BSA conjugate (50 µg) with aqueous adjuvant (Freund's adjuvant). After 30 days of each immunization, body weight, GSI and sperm quality were observed in the immunized groups and compared with the control group.
Results: Body weight showed alterations in immunized animals as compared to control. However, GSI, sperm motility, sperm count and sperm morphology were significantly decreased in immunized animals throughout the experimental investigation and these effects were more prominent and significant in the later part of the experiment.
Conclusion: These results suggested that the active immunization against GnRH produced bioeffective antibodies as indicated by significant reduction in GSI level and sperm quality and induced infertility in male mice.

Abstract

Background: The beneficial role of cabergoline as a prophylactic agent to prevent ovarian hyper stimulation syndrome (OHSS) among high-risk patients has been demonstrated in previous studies. But data for its role as a treatment for established severe OHSS is still limited. We represent the treatment results of high dose oral cabergoline in management of six patients after the syndrome is established.
Case: High-dose oral cabergoline (1 mg daily for eight days) was prescribed as an adjuvant to symptomatic treatment for six hospitalized patients with established severe OHSS following infertility treatment cycles. In two cases OHSS resolved rapidly despite the occurrence of ongoing pregnancy.
Conclusion: Considering the treatment outcomes of our patients, high dose cabergoline did not eliminate the need for traditional treatments, but it was a relatively effective and safe therapy in management of established severe OHSS, and prevented the increase in its severity following the occurrence of pregnancy.

Abstract

Background: We often see patients with a thin endometrium in ART cycles, in spite of standard and adjuvant treatments. Improving endometrial growth in patients with a thin endometrium is very difficult. Without adequate endometrial thickness these patients, likely, would not have reached embryo transfer.
Objective: We planned this study to investigate the efficacy of intrauterine granulocyte colony-stimulating factor (G-CSF) perfusion in improving endometrium, and possibly pregnancy rates in frozen-thawed embryo transfer cycles.
Materials and Methods: This is a non-randomized intervention clinical trial. Among 68 infertile patients with thin endometrium (-7 mm) at the 12th-13th cycle day, 34 patients received G-CSF. G-CSF (300 microgram/1mL) to improve endometrial thickness was direct administered by slow intrauterine infusion using IUI catheter. If the endometrium had not reached at least a 7-mm within 48-72 h, a second infusion was given. Endometrial thickness was assessed by serial vaginal ultrasound at the most expanded area of the endometrial stripe.
Results: The cycle was cancelled in the patients with thin endometrium (endometrial thickness below 7mm) until 19th cycle day ultimately The cycle cancelation rate owing to thin endometrium was similar in G-CSF group (15.20%), followed by (15.20%) in the control group (p=1.00). The endometrial growth was not different within 2 groups, an improvement was shown between controlled and G-CSF cotreated groups, with chemical (39.30% vs. 14.30%) and clinical pregnancy rates (32.10% vs. 12.00%) although were not significant.
Conclusion: Our study fails to demonstrate that G-CSF has the potential to improve endometrial thickness but has the potential to improve chemical and clinical pregnancy rate of the infertile women with thin endometrium in frozen-thawed embryo transfer cycle.

Abstract

Background: Recently there is a focus on the antioxidants as adjuvant treatment of polycystic ovary syndrome (PCOS), the most endocrinopathy in reproductive age women.
Objective: The aim of this review is answer to the question whether antioxidants are effective for managing of hormonal and metabolic problems in women with PCOS based on first degree evidences from Iran.
Materials and Methods: A systematic review of clinical trials was done in Persian and international databases including PubMed, Scientific Information Database, Google Scholar, Iran Medex, and Magiran up to 2013. Keywords were including polycystic ovary syndrome, Iran, vitamin, antioxidant. From 440 potential studies found electronically, 11 studies; including 444 women in intervention and 390 women in control groups. Intervention in three studies was Calcium-vitamin D or calcitriol; in three studies was ω-3 fatty acids; in two studies was N-acetyl cysteine; in one study was folic acid; in one study was Zinc; and in one study was Soy.
Results: Finally, 11 studies that were relevant and met the inclusion criteria reviewed. There were 7 studies in English and 4 studies in Persian. We couldn’t include all studies because all full texts were not accessible.
Conclusion: The results showed that antioxidants and vitamins have positive effects on management of PCOS women. Although it seems more studies is necessary in this field.

Abstract

Background: 30% of patients with polycystic ovary syndrome (PCOS) show mild, transient hyperprolactinemia. It is suggested that a reduction of the dopamine inhibitory effect might raise both prolactin and luteinizing hormone.
Objective: To investigate the adjuvant cabergoline therapy effects on menstrual irregularity and androgen system in PCOS women with hyperprolactinemia.
Materials and Methods: This randomized clinical trial was done on 110 polycysticovary syndrome women with increased serum prolactin concentration [1.5 fold morethan normal level (>37.5 ng/ml)]. Participants were divided into two groups: Casegroup (n=55) treated with metformin 1gr/day and cabergoline 0.5 mg/week for 4months and control group (n=55) treated with metformin 1g/day and placeboweekly. Testosterone, prolactin, and dehydroepiandrosterone sulfate level weremeasured before and four months after intervention in two groups. Also, situation ofmenstrual cycles asked and recorded before and after intervention.
Results: We found decrease in the mean of dehydroepiandrosterone sulfate, weightand total testosterone level in the two groups after intervention but their changeswere not significant. Patients in case group showed a significant decrease in serumprolactin level before and after intervention (p<0.001), but no difference was foundin control group. All patients in both studied groups had irregular menstrual cycles,which regulate after intervention and the difference was significant (p=0.02).
Conclusion: The results showed that cabergoline can be used as a safe administration in PCOS patients with hyperprolactinemia to improve the menstrual cycles. Considering that the administration of cabergoline plus metformin may reduce the required duration and dose of metformin, patient acceptability of this approach is higher.

Abstract

Background: 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.
Objective: This study was conducted to investigate the effects of ethyl pyruvate (EP) in reducing the CP-induced side effects on reproductive system.
Materials and Methods: 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.
Results: 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).
Conclusion: The results of this study revealed ameliorating effects of EP on sperm quality of CP treated animals.

Abstract

Background: Different investigation showed that 5-methoxypsoralen and 8- methoxypsoralen reduce birth rates in the rats.
Objective: In this study we worked out the effect of methoxsalen together with ultraviolent A (UVA) radiation on mature Balb/C mice spermatogenesis.
Materials and Methods: The LD50 standard was determined 160 mg/kg and the UVA dose which causes erythema was calculated 0.046 J/cm2. A sub-lethal dose of 80 mg/kg of methoxsalen solution was injected intrapritoneally to mature mice and after one hour they were exposed to UVA radiation for 20 minutes. Experiments applied included methoxsalen alone, methoxsalen with UVA, UVA alone, sham group (a group received Tween 80), and control group (N=6). In all experimental groups except UVA alone group, injections were carried out, during two consecutive weeks. Serial cross sections (5 µm thickness) were prepared for morphological and histological studies. Tunica albuginea diameter, and number of type A and type B spermatogonia and histological investigation of the testes were measured.
Results: Microscopical and statistical analyses showed significant anomalies among the experimental groups compared to control and sham group. These anomalies included decrease the body weight; increase the relative testis weight; and decrease the number of spermapogonia (type A and B), primary spermatocytes, spermatids and sperms in experimental groups I and II compared to control group. Our results showed the number of spermatozoa in experimental group I was 22.6±2.12, in experimental group II was 33.6±2.05 and in control group was 44.3±2.77 (p<0.05). Moreover in some experimental groups (I and II) shrinkage of seminiferous tubules and release of primary spermatocyte and spermatids were observed to the lumen of them.
Conclusion: It is concluded from the results of this work that treatment with methoxsalen with UVA can damage and disorganize seminiferous tubules and decrease spermatogenic cells.

Abstract

Background: N-acetyl cysteine (NAC) was proposed as an adjuvant to clomiphenecitratefor ovulation induction in patients with polycystic ovary syndrome (PCOS)without clomiphene citrate resistance.
Objective: To evaluate the effect of NAC on pregnancy rate in PCOS patients whowere candidates for intrauterine insemination.
Materials and Methods: In this randomized clinical trial 97 PCOS women aged 18-38 years were enrolled in two groups, randomly. For the case group (n=49), NAC(1.2 gr) + clomiphene citrate (100 mg) + letrozole (5mg) were prescribed dailyfromthe third day of menstruation cycle for five days. The control group (n=48) had thesame drug regimen without NAC. In order to follicular development, GONAL-Fwas injected on days of 7-11 menstrual cycles in all participants. When the folliclesize was 18mm or more, HCG (10000 IU) was injected intramuscular and theintrauterine insemination was performed after 34-36 hr.
Results: There was no significant difference between study groups regarding BMI(p=0.28), FSH level (p=0.66), LH level (p=0.67), mean endometrial thickness(p=0.14), mean number of mature follicles (p=0.20) and the pregnancy occurrence(p=0.09).
Conclusion: NAC is ineffective in inducing or augmenting ovulation in PCOSpatients who were candidates for intrauterine insemination and cannot berecommended as an adjuvant to CC in such patients.

Abstract

Abstract
Background: Ovarian stimulation (OS) for poor ovarian response (POR) patients is still a major challenge in assisted reproductive techniques. Aromatase inhibitors as co-treatment in antagonist protocol are suggested to these patients, but there are controversial reports.
Objective: To evaluate the effectiveness Letrozole (LZ) as adjuvant treatment in gonadotropin-releasing hormone (GnRH)-antagonist protocol in POR patients undergoing in vitro fertilization/ intracytoplasmic sperm injection cycles.
Materials and Methods: This double-blind randomized clinical trial was conducted in Arash women's hospital. One hundred sixty infertile women with POR based on Bologna criteria were allocated into two groups randomly: LZ + GnRH-antagonist (LA) and placebo + GnRH-antagonist (PA) groups. In the experimental group, the patients received 5 mg LZ on the first five days of OS with 150 IU of recombinant human follicle-stimulating hormone (rFSH) and 150 IU of human menopausal gonadotropin (HMG). The cycle outcomes were compared between groups.
Result: The total number of retrieved oocytes and the metaphase II oocytes in LA-treated group were significantly higher than those in the control group (p = 0.008, p = 0.002). The dosage of hMG used and the duration of OS and antagonist administration in LZ-treated group were significantly lower than those of the control group. The number of patients with no oocyte, in the control group, was higher than the LZ-treated group, and the clinical pregnancy rate in LA-treated group (25%) was higher than the control group (18%); however, the differences were not significant statistically.
Conclusion: Adding 5 mg of LZ to rFSH/hMG antagonist protocol may improve the in vitro fertilization/intracytoplasmic sperm injection cycle outcome in POR patients.
