Abstract
Objectives: The current research was established to make a comparison between the delayed-start GnRH antagonist and flare-up GnRH agonist protocols in poor response patients. Methods: The present study is a randomized, prospective, controlled trial that was performed on 150 women who referred to two distinct in vitro fertilization (IVF) centers in Iran. Patients were randomly assigned to two experimental groups, as one group was treated with the delayed-start GnRH antagonist protocol (delayed-start group), while another group was treated with the flare-up protocol (flare-up group). Results: The serum concentrations of estradiol and progesterone, along with the thickness of endometrial tissue and the number of follicles ≥13 mm was significantly increased in the delayed-start group compared with the flare-up group. Also, the number of total oocytes, retrieved mature oocytes, total embryos, fertilized oocytes, as well as the quality of embryos were markedly higher in the delayed-start group when compared with the flare-up group. No statistically significant difference was found in the rates of fertilization, implantation, and pregnancy between the two experimental groups. Conclusions: According to the above evidence, it seems that the effect of delayed-start protocol on ovarian responsiveness was more pronounced during controlled ovarian stimulation in comparison with the flare-up protocol and the delayed start protocol probably lead to better implantation and pregnancy rates in comparison with the flare up agonist protocol cycle in poor responders.

Abstract
Background Insulin resistance (IR) occurs in 50–70% of women with polycystic ovary syndrome (PCOS) and can be applied as a prediabetic feature in PCOS. Objective In this study, indirect methods including fasting blood sugar (FBS), fasting insulin (FI), FBS/FI ratio, and quantitative insulin sensitivity check index (QUICKI) were compared with the homeostasis model assessment of insulin resistance (HOMA-IR) as a standard technique. The association of IR to sex hormone-binding globulin (SHBG) and several hormones was also analyzed. Materials and Methods This cross-sectional study was performed on 74 PCOS women. Sensitivity and specificity of each IR method was calculated based on HOMA-IR. Hormonal profiles of the patients were compared between the groups with defined normal and abnormal values of IR. Results Triglyceride levels had a positive association with FBS and HOMA-IR (p = 0.002 and p = 0.01, respectively) with a negative association to QUICKI and SHBG (p = 0.02 and p = 0.02, respectively). SHBG showed a significant negative association with FBS (p = 0.001). Dehydroepiandrosterone sulfate showed a positive association with FI (p = 0.002). Seven PCOS women showed abnormal SHBG levels (< 36 nmol/L) while expressed normal values of the rest of the studied variables. FI and QUICKI had the highest sensitivity while FBS/FI and QUICKI had the highest specificity when HOMA-IR was applied as a standard test. Conclusion SHBG and triglyceride had a significant negative and positive association with IR, respectively. HOMA-IR followed by FI and QUICKI is the most sensitive test for the detection of IR. SHBG levels can be a helpful biomarker for the diagnosis of PCOS.

Abstract
INTRODUCTION Recent studies have addressed the role of micronutrients in fertilization, such as vitamin D. The present study aims to explore the effects of using calcitriol, an active form of vitamin D, on IVF results in women with vitamin D deficiency. METHOD This double-blinded randomized clinical trial was done on 180 infertile women, undergone IVF treatment. Out of them, 95 were found to have vitamin D deficiency (blood serum 25-dihydroxy vitamin D <30 ng/ml). Fifty one women in experimental group were treated with two 0.25 µg calcitriol pills daily during 4 weeks (discontinued 8 hours prior to the embryo transfer) and 44 subjects to the placebo group (mean vitamin D deficiency 27.5 ±1.8 in case group vs. 27.6±1.8 in control group, P>0.05). Final analysis includes outcomes of chemical and clinical pregnancy was done on 74 women (including 36 in case and 38 in control group). RESULTS Our study showed that in the experimental group, chemical pregnancy success was significantly higher than that in the control group, 31.4 vs. 18.2% (P<0.05). However, there were no significant differences between the 2 groups in reaching the clinical pregnancy stage (25.5% in case group vs. 13.6% in control group) and continuation of pregnancy into week 20 (9.8% in case group vs. 11.6% in control group) (P>0.05). CONCLUSION Calcitriol administration by improving the implantation process can significantly increase the chances of successful IVF cycle results in infertile women with vitamin D deficiency.

Determining an optimal cut-off value for follicle-stimulating hormone to predict microsurgical testicular sperm extraction outcome in patients with non-obstructive azoospermia. ARCHIVES OF ENDOCRINOLOGY AND METABOLISM 2020; 64:165-170. [PMID: 32236315 PMCID: PMC10118940 DOI: 10.20945/2359-3997000000217] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Accepted: 07/03/2019] [Indexed: 11/23/2022]
Abstract
Objective To determine the optimal cut-off value for follicle stimulating hormone (FSH) to predict the outcome of microsurgical testicular sperm extraction (micro-TESE) in patients with nonobstructive azoospermia (NOA). Subjects and methods We included a total number of 180 patients with NOA. The serum level of FSH was determined and all the subjects underwent micro-TESE. We determined the optimal cut-off value for FSH and assessed whether the test could be effectively used as a successful predictor of sperm retrieval by calculating the Receiver Operating Characteristic (ROC) area under the curve. Results Overall we included a total number of 171 patients with mean age of 34.3 ± 8.6 years. The micro-TESE was considered to be successful in 79 (43.8%) while it failed in 92 (56.2%) patients. We found that the mean level of serum FSH was significantly higher in group those with failed micro-TEST compared to successful group (p < 0.001). The cut-off value for FSH was calculated to be 14.6 mIU/mL to predictive the outcome of micro-TESE with a sensitivity of 83.5% [73.5%-90.9%] and a specificity of 80.3% [69.5%-88.5%]. At this value, the other parameters were calculated to be PPV, 81.5%; NPV, 82.4; LR+, 4.23; and LR-, 0.21. Conclusions The results of the current study indicate that FSH plasma levels above 14.6 mIU/mL can be considered to be the failure predictor of the micro-TESE in NOA patients.

Comparing The Effects of Glycyrrhiza glabra Root Extract, A Cyclooxygenase-2 Inhibitor (Celecoxib) and A Gonadotropin-Releasing Hormone Analog (Diphereline) in A Rat Model of Endometriosis. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2019; 13:45-50. [PMID: 30644244 PMCID: PMC6334018 DOI: 10.22074/ijfs.2019.5446] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Accepted: 06/26/2018] [Indexed: 12/27/2022]
Abstract
Background The purpose of this study was to compare the effects of Glycyrrhiza glabra (Licorice), a cyclooxyge-
nase-2 inhibitor (Celecoxib) and a gonadotropin-releasing hormone analog (Diphereline®), with a control group on
endometrial implants in rats. Materials and Methods In this experimental study, endometriosis was induced in rats by auto transplantation and
after confirmation, the rats were divided into 4 groups that were treated for 6 weeks with normal saline (0.5 ml/day,
orally), licorice extract (3000 mg/kg/day, orally), celecoxib (50 mg/kg, twice a day, orally) or diphereline (3 mg/kg,
intramuscularly). At the end of treatments, the mean area, volume, histopathology and hemosiderin-laden macrophage
(HLM) counts of the endometrial implants were evaluated and compared among the four groups. Results The mean area, volume and HLM counts of the implants in the licorice group were significantly lower than
those of the control group (P<0.001). The histopathologic grades of endometrial implants were significantly decreased
by licorice compared to the control group (P<0.001). There was no significant change in the mentioned parameters in
rats treated with celecoxib compared to the control group. Diphereline was the most potent agent for suppressing the
growth of endometrial implants in terms of all of the above-mentioned parameters. Conclusion Licorice decreased the growth and histopathologic grades of auto-transplanted endometrial implants.
However, while celcoxib had no significant effect, diphereline showed the highest potency for decreasing the endome-
trial growth. Licorice may have the potential to be used as an alternative medication for the treatment of endometriosis.

Abstract
OBJECTIVE Comparing oxytocin level and some other parameters between infertile women with or without polycystic Ovary Syndrome (PCOS), to evaluate the correlation between oxytocin with anti-mullerian hormone (AMH), Body Mass Index (BMI) and insulin resistance (IR). MATERIALS AND METHODS This cross-sectional study was performed on 80 PCOS and 81 non-PCOS women as the control group. Oxytocin, various hormones, Oral glucose tolerance test (OGTT) and Homeostatic model assessment of insulin resistance (HOMA-IR) were compared between two groups. Correlations between parameters were assessed by the spearman's rank correlation coefficient. Cutoff values for oxytocin and AMH in PCOS were calculated by the ROC-Curve and DeLong method. RESULTS The mean oxytocin level was statistically lower in the case group (p ≤ 0.001). The mean BMI, AMH, HOMA-IR, fasting insulin and insulin 2-h after 75-g glucose were significantly higher in the PCOS group. Oxytocin was negatively correlated to AMH when evaluated for all participants or only among controls. Moreover oxytocin was negatively correlated to HOMA-IR among all participants. However the relationship between oxytocin and BMI was not statistically significant. The calculated cutoff value for oxytocin was 125 ng/L and for AMH was 3.6 ng/mL in the PCOS group. CONCLUSION The mean oxytocin level in the PCOS infertile women was lower than non-PCOS women. Oxytocin showed a significant reverse correlation with AMH and HOMA-IR.

Abstract
Objectives We sought to determine the effects of the delayed start protocol with gonadotropin-releasing hormone (GnRH) antagonists in poor responders undergoing in vitro fertilization (IVF). Methods This randomized clinical trial was conducted during a 15-month period from April 2014 to July 2015 in clinics in Shiraz, Iran. A total of 42 poor responders with primary infertility were randomly assigned to the controlled ovarian stimulation group utilizing the delayed start protocol (n = 21) or the traditional group (n = 21) using GnRH antagonist, Cetrotide. The primary endpoint was the number of patients undergoing oocyte pick-up, implantation, and the rate of pregnancy. Results The baseline characteristics of the two study groups were comparable including age, infertility duration, and body mass index. The number of follicles measuring > 13 mm in diameter (p = 0.057), retrieved oocytes (p = 0.564), mature metaphase II oocytes (p = 0.366), embryos (p = 0.709), and transferred embryos (p = 0.060) were comparable between the two groups. The number of patients undergoing oocyte pick-up (p = 0.311), the rates of implantation (p = 0.407), and pregnancy (p = 0.596) were also comparable between the two groups. Conclusions The delayed start protocol was not associated with better conception results or cycle outcomes in poor responders with primary infertility undergoing IVF cycles.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is a serious complication of ovulation induction that usually occurs after gonadotropin stimulation, followed by human chorionic gonadotropin administration, for infertility treatment. The existing knowledge about the pathophysiology, risk factors, and primary and secondary methods for the prevention of OHSS is reviewed in this manuscript. The clinical manifestations and characteristics of mild, moderate, severe, and critical forms of the syndrome are defined. The methods of handling affected cases as outpatient or in-hospital management methods as well as indications for hospitalization are summarized in this review. The clinical and biochemical routes of assessing and monitoring hospitalized patients with OHSS, various drugs and medical treatment strategies including indications for aspiration of the ascitic fluid and pleural effusion, and also rare indications for surgery are briefly explained in this article. Severe OHSS, which two decades ago was considered an iatrogenic life-threatening condition, can now be effectively prevented or managed during the early stages. An OHSS-free clinic can be established nowadays by carefully considering the endocrinology of ovulation and using appropriate and dose-adjusted pharmaceutical agents, which are summarized and discussed in this review.

Abstract
Background Y chromosome deletions (YCDs) in azoospermia factor (AZF) region are associated with ab-
normal spermatogenesis and may lead to azoospermia or severe oligozoospermia. Assisted reproductive tech-
nologies (ART) by intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) are com-
monly required for infertility management of patients carrying YCDs. The aim of this study was to estimate
the frequency of YCDs, to find the most frequent variant in infertile men candidate for ART and to compare
YCD distribution with a control fertile group. The semen parameters, hormonal profiles and ART outcomes
of the infertile group were studied.
Materials and Methods This case-control study consisted of 97 oligozoospermic or non-obstructive azoospermic
(NOA) infertile men, who had undergone ART, as the case group and 100 fertile men as the control group. DNA
samples were extracted from blood samples taken from all 197 participants and YCDs were identified by multiplex
polymerase chain reaction (PCR) of eight known sequence-tagged sites. The chi-square test was used to compare
the mean values of hormone and sperm parameters between the two groups. P<0.05 was considered statistically
significant. Results No YCD was detected in the control group. However, 20 out of 97 (20.6%) infertile men had a YCD. AZFc,
AZFbc and AZFabc deletions were detected in 15 (75%), four (20%) and one (5%) YCD-positive patients. No fer-
tilization or clinical pregnancy was seen following ICSI in this sub-group with YCD. The mean level of FSH was
significantly higher in the group with YCD (28.45 ± 22.2 vs. 4.8 ± 3.17 and 10.83 ± 7.23 in YCD-negative patients
with and without clinical pregnancy respectively). Conclusion YCD is frequent among NOA men and YCD screening before ART and patient counseling is thus
strongly recommended.

Abstract
BACKGROUND Despite the large number of papers published on the efficiency of different exogenous gonadotropins, no confirmed protocol exists. Therefore, the aim of the present study was to compare the efficacy of 4 exogenous gonadotropins in IVF/ICSI cycles. METHODS This study, performed from January 2014 to May 2014, recruited 160 women referred to Ghadir Mother and Child Hospital and Dena Hospital, Shiraz, Iran. The patients underwent standard downregulation and were randomly divided into 4 groups of A, B, C, and D and were administered hMG, hFSH, rFSH, and combined sequential hFSH/rFSH, respectively. Then, the duration of stimulation, number of oocytes and embryos as well as their quality, implantation rate, biochemical and clinical pregnancy rate, and live birth rate in each group were evaluated. RESULTS Group D patients required significantly fewer ampoules of FSH than did the women in groups A, B, and C (P=0.004). The duration of stimulation was significantly longer in group C than in groups A and D (P=0.030). The serum estradiol level was significantly higher in group D than in groups B and C (P=0.005). A significantly higher number of large-sized follicles was observed in group D than in group B (P=0.036). CONCLUSION Our data revealed no statistically significant differences in the mean oocyte number, embryo quality, clinical pregnancy rate, or live birth rate between the hMG, hFSH, rFSH, and sequential hFSH/rFSH protocols. However, several differences in the duration of stimulation, serum estradiol levels, and number of large-sized follicles were detected between the groups.

Abstract
Diminished ovarian reserve (DOR) significantly decreases the success rate of the assisted reproductive technique (ART). In this study, we assessed the effect of melatonin on the ART outcomes in women with DOR. A double-blinded, randomized, clinical trial was performed on 80 women with DOR as a pilot study in Shiraz, between 2014 and 2015. DOR was defined as the presence of 2 of the following 3 criteria: 1) anti-Müllerian hormone ≤1, 2) follicle-stimulating hormone ≥10, and 3) bilateral antral follicle count ≤6. The women received 3 mg/d melatonin or a placebo since the fifth day of one cycle prior to gonadotropin stimulation and continued the treatment up to the time of ovum pickup. The ART outcomes were compared between the groups using SPSS software. Finally, there were 32 women in the case and 34 in the placebo groups. The mean age and basal ovarian reserve test were the same between the groups. The serum estradiol level on the triggering day was significantly higher in the case group (P=0.005). The mean number of MII oocytes was higher in the case group, but the difference did not reach statistical significance. Number of the patients who had mature MII oocytes (P=0.014), top-quality embryos with grade 1 (P=0.049), and embryos with grades 1 and 2 (P=0.014) was higher among the women who received melatonin. However, the other ART outcomes were not different between the groups. The serum estradiol level was higher and more women with DOR had good-quality oocytes and embryos after receiving melatonin; however, no other outcome was different between the case and control groups. Trial Registration Number: IRCT2014041417264N1.

Abstract
BACKGROUND Uterus contractibility is considered a powerful prognostic factor in predicting the embryo transfer outcome. Moreover, uterine contractions are known to be stimulated by prostaglandins which are produced by cyclooxygenase from arachidonic acid. As such, suppressing the inflammatory response and contractions using anti-inflammatory and relaxant agents is expected to result in increased success rate of embryo transfer and artificial insemination. OBJECTIVE To investigate the effect of piroxicam administration on the success rate in intrauterine insemination (IU) cycles in patients presenting with unexplained infertility. MATERIALS AND METHODS This randomized, placebo-controlled clinical trial included 260 women with unexplained infertility undergoing IUI cycles. Patients were randomly assigned to receive either piroxicam ten mg/day on days 4-6 after IUI or placebo (control group). The main outcome measures were number of IUI cycles, pregnancy, abortion, and multiple pregnancy rates. RESULTS The pregnancy rate was found to be 25 (19.2%) and 16 (12.3%) in piroxicam and control groups, respectively (p = 0.039). Five patients (3.8%) in piroxicam group experienced twin pregnancy whereas only three patients (2.3%) in control group had twin pregnancy (p = 0.361). The pregnancy rate per cycle was also significantly higher in those who received piroxicam as compared to controls (11.16 vs. 6.66; p = 0.021). CONCLUSION Administration of piroxicam after IUI is associated with decreased number of cycles, as well as increased pregnancy rate and pregnancy rate per cycle in IUI cycles. However, piroxicam did not have any effect on abortion, multiple pregnancy, and ongoing pregnancy rates.

Abstract
Background and Objectives Previously, various methodologies were used to enumerate the endothelial progenitor cells (EPCs). We now know that these methodologies enumerate at least three different EPC subsets: circulating angiogenic cells (CACs), colony-forming unit endothelial cells (CFU-ECs), and endothelial colony-forming cells (ECFCs). It is not clear whether there is a correlation between changes in the number of these subsets. The aim of the current study is to find an answer to this question. Materials and Methods The number of all EPC subsets was quantified in the peripheral blood of nine pregnant women in their first and third trimesters of pregnancy. We enumerated 14 cell populations by quantitative flow-cytometry using various combinations of the markers, CD34, CD133, CD309, and CD45, to cover most of the reported phenotypes of CACs and ECFCs. Culturing technique was used to enumerate the CFU-ECs. Changes in the number of cells were calculated by subtracting the number of cells in the first trimester peripheral blood from the number of cells in the third trimester peripheral blood, and correlations between these changes were analyzed. Results The number of CFU-ECs did not correlate with the number of ECFCs and CACs. Also, CACs and ECFCs showed independent behaviors. However, the number of CACs showed a strong correlation with the number of CD133+CD309+ cells (p=0.001) and a moderate correlation with the number of CD34+CD309+ cells (p=0.042). Also, the number of ECFCs was correlated with the number of CD309+CD45- cells (p=0.029) and CD34+CD45- cells (p=0.03). Conclusion Our study showed that the three commonly used methods for quantifying EPC subsets represent different cells with independent behaviors. Also, any study that measured the number of EPCs using the flow cytometry method with a marker combination that lacks CD309 may be inaccurate.

[PMID: 24799855 PMCID: PMC4009584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2013] [Revised: 08/19/2013] [Accepted: 08/25/2013] [Indexed: 11/03/2022]
Abstract
BACKGROUND The direct effect of hCG on the human endometrium was studied several times. OBJECTIVE The objectives of this study were to evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). MATERIALS AND METHODS In this randomized placebo-controlled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/ intracytoplasmic sperm injection (IVF-ICSI) cycles were randomly assigned to receive 250μg intrauterine rhCG (n=84) or placebo (n=98) before ET. The implantation and pregnancy rates were compared between groups. RESULTS Patients who received intrauterine rhCG before ET had significantly higher implantation (36.9% vs. 22.4%; p=0.035), clinical pregnancy rates (34.5% vs. 20.4%; p=0.044) and ongoing pregnancy rate (32.1% vs. 18.4%; p=0.032) when compared to those who received placebo. The abortion (2.4% vs. 2.0%; p=0.929) and ectopic pregnancy rates (1.2% vs. 1.0%; p=0.976) were comparable between groups of rhCG and placebo, respectively. CONCLUSION Intrauterine injection of 250μg of rhCG before ET significantly improves the implantation and pregnancy rates in IVF/ICSI cycles.

Pregnancy rate after endometrial injury in couples with unexplained infertility: A randomized clinical trial. IRANIAN JOURNAL OF REPRODUCTIVE MEDICINE 2013; 11:869-74. [PMID: 24639710 PMCID: PMC3941397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2013] [Revised: 05/28/2013] [Accepted: 07/02/2013] [Indexed: 12/03/2022]
Abstract
BACKGROUND Unexplained infertility is still a challenging issue as to its causes, appropriate management and treatment. Evidence implicates early embryopathy or implantation failure as likely causes. OBJECTIVE This study aims to investigate the effect of local endometrial injury on pregnancy rate in selected unexplained infertile patients. MATERIALS AND METHODS This was a randomized clinical trial conducted in Shiraz University Infertility Clinic of Ghadir Hospital. A total of 217 women with unexplained infertility aged 23-35 years old were randomly divided into two study groups through block randomization. After superovulation by clomiphene-citrate and gonadotropins and when the dominant follicles reached 18-20 mm, patients were randomly assigned to undergo endometrial local injury at posterior uterine wall by piplle endometrial sampling (n=114) or mock pipette biopsy (n=103) during pre-ovulatory days (when spontaneous urinary LH surge was detected). Then all the patients were instructed to follow a regularly timed intercourse. RESULTS The pregnancy rate was significantly higher in the endometrial injury group compared to the control group [17/114 (14.9%) vs. 6/103 (5.8%) (OR: 2.83 95% CI: 1.07-7.49, p=0.03]. The abortion rate was comparable between two groups (17.64% vs. 14.28%; p=0.701). CONCLUSION Local mechanical injury of the endometrium can enhance the uterine receptivity and facilitates the embryo implantation. This simple, easy, and cost effective procedure is worth considering in selective unexplained infertility patients who implantation failure is the likely causes of infertility before complex treatments. This procedure may help reduce psychological tensions and high expenses imposed through such interventions. Registration ID in IRCT: IRCT2012082510657N1.

Serum Levels of Anti-histone and Anti-double-Strand DNA Antibodies Before and After Laparoscopic Ovarian Drilling in Women with Polycystic Ovarian Syndrome. J Obstet Gynaecol India 2013; 64:47-52. [PMID: 24587607 DOI: 10.1007/s13224-013-0451-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2011] [Accepted: 06/14/2012] [Indexed: 11/26/2022] Open
Abstract
OBJECTIVES To determine the serum levels of anti-dsDNA, anti-histone, and anti-nucleosome antibodies after laparoscopic ovarian electrocauterization in patients with polycystic ovarian syndrome (PCOS). METHODS Our study was performed on 35 patients with PCOS resistant to medical therapy, 35 patients with unexplained infertility, and 35 healthy fertile individuals. Patients with PCOS underwent laparoscopic electrocauterization while those with unexplained infertility underwent diagnostic laparoscopy. Serum levels of anti-dsDNA, anti-histone, and anti-nucleosome antibodies were measured at baseline and 1 month after operation and were compared between groups. RESULT Baseline characteristics were similar between groups. Patients with PCOS had significantly higher levels of anti-dsDNA compared to unexplained infertility (p < 0.001) and control groups (p = 0.001). Anti-histone antibodies were higher in PCOS group compared to control group (p = 0.001). In those patients suffering from PCOS, anti-histone antibody increased significantly 1 month after ovarian electrocauterization (p = 0.017). Similarly, serum levels of anti-nucleosome antibodies increased significantly 1 month after operation (p < 0.001). CONCLUSION Laparoscopic ovarian electrocauterization in patients with PCOS results in increased levels of anti-histone and anti-nucleosome antibodies. Anti-dsDNA, anti-histone, and anti-nucleosome antibodies also increase after diagnostic laparoscopy in those with unexplained infertility. Patients with PCOS have higher levels of anti-dsDNA and anti-histone antibodies compared to those with unexplained infertility and healthy fertile subjects.

Surgical management of a rare form of cervical dysgenesis with normal vagina, normal vaginal portion of the cervix and obstructed uterus. ARCHIVES OF IRANIAN MEDICINE 2013; 16:246-8.

Abstract
This case was an extremely rare form of cervical dysgenesis that presented with cyclic pain. Diagnostic laparoscopy and vaginoscopy showed the presence of a blind uterus at the level of the internal cervical os with a normal vagina and exocervix. Müllerian ducts are the embryologic origin for the uterus, cervix and upper part of the vagina. Müllerian duct migration initiates from the upper part of the Müllerian system. Therefore an obstructed uterus is usually associated with cervical and upper vaginal anomalies. This case was unusual because of the presence of an isolated segmental atresia at the level of the internal cervical os. However the vaginal portion of the cervix, vagina and urinary system were normal. We theorized that the absence of an appropriate fusion between the Müllerian duct and its underlying mesoderm, loss of cell-to-cell communication and special gene expression during a critical time period or a vascular accident between 12-22 weeks of gestation might have caused this anomaly. The patient underwent a laparotomy to create a utero-cervical canal using a peritoneal graft.

Metformin versus chromium picolinate in clomiphene citrate-resistant patients with PCOs: A double-blind randomized clinical trial. IRANIAN JOURNAL OF REPRODUCTIVE MEDICINE 2013; 11:611-8. [PMID: 24639797 PMCID: PMC3941367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2012] [Revised: 09/01/2012] [Accepted: 03/13/2013] [Indexed: 12/04/2022]
Abstract
BACKGROUND Chromium picolinate could be effective in clomiphen citrate resistant PCOS patients. OBJECTIVE To compare the effects of chromium picolinate vs. metformin in clomiphen citrate resistant PCOS patients. MATERIALS AND METHODS The present randomized clinical trial was performed on 92 women with clomiphen citrate-resistant PCOS at the clinics which were affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. The subjects were randomly assigned to two groups receiving either chromium picolinate (200µg daily) or metformin (1500mg daily) for 3 months. Anthropometric and hormonal profile were measured and compared both before and after the treatment. Ovulation and pregnancy rate was measured in the two study groups, as well. RESULTS Chromium picolinate significantly decreased fasting blood sugar (FBS) after 3 months of treatment (p=0.042). In the same way, the serum levels of fasting insulin had significantly decreased leading to an increase in insulin sensitivity as measured by QUICKI index (p=0.014). In comparison to the patients who received chromium picolinate, those who received metformin had significantly lower levels of testosterone (p=0.001) and free testosterone (p=0.001) after 3 months of treatment. Nevertheless, no significant difference was found between the two study groups regarding ovulation (p=0.417) and pregnancy rates (p=0.500). CONCLUSION Chromium picolinate decreased FBS and insulin levels and, thus, increased insulin sensitivity in clomiphene citrate-resistance PCOS women. These effects were comparable with metformin; however, metformin treatment was associated with decreased hyperandrogenism. Overall, chromium picolinate was better tolerated compared to metformin; nonetheless, the two study groups were not significantly different regarding ovulation and pregnancy rates.

Male reproductive health under threat: Short term exposure to radiofrequency radiations emitted by common mobile jammers. J Hum Reprod Sci 2013; 6:124-8. [PMID: 24082653 PMCID: PMC3778601 DOI: 10.4103/0974-1208.117178] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2013] [Revised: 06/09/2013] [Accepted: 06/25/2013] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Modern life prompted man to increasingly generate, transmit and use electricity that leads to exposure to different levels of electromagnetic fields (EMFs). Substantial evidence indicates that exposure to common sources of EMF such as mobile phones, laptops or wireless internet-connected laptops decreases human semen quality. In some countries, mobile jammers are occasionally used in offices, shrines, conference rooms and cinemas to block the signal. AIMS To the best of our knowledge, this is the first study to investigate the effect of short term exposure of human sperm samples to radiofrequency (RF) radiations emitted by common mobile jammers. SUBJECTS AND METHODS Fresh semen samples were collected by masturbation from 30 healthy donors who had referred to Infertility Treatment Center at the Mother and Child Hospital with their wives. Female problem was diagnosed as the reason for infertility in these couples. STATISTICAL ANALYSIS T-test and analysis of variance were used to show statistical significance. RESULTS The motility of sperm samples exposed to jammer RF radiation for 2 or 4 h were significantly lower than those of sham-exposed samples. These findings lead us to the conclusion that mobile jammers may significantly decrease sperm motility and the couples' chances of conception. CONCLUSION Based on these results, it can be suggested that in countries that have not banned mobile jammer use, legislations should be urgently passed to restrict the use of these signal blocking devices in public or private places.

A randomized, controlled clinical trial comparing the effects of aromatase inhibitor (letrozole) and gonadotropin-releasing hormone agonist (triptorelin) on uterine leiomyoma volume and hormonal status. Fertil Steril 2010; 93:192-8. [PMID: 19135657 DOI: 10.1016/j.fertnstert.2008.09.064] [Citation(s) in RCA: 82] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2008] [Revised: 09/16/2008] [Accepted: 09/19/2008] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To examine and compare the efficacy and safety of GnRH agonist (GnRHa) vs. aromatase inhibitor in premenopausal women with leiomyomas. DESIGN Multicenter, randomized, controlled clinical trial. SETTING University hospitals. PATIENT(S) A total of 70 subjects with a single uterine myoma measuring >or=5 cm. Subjects were randomized into two groups with use of a random table. They were treated with aromatase inhibitor (group A) or GnRHa (group B). INTERVENTION(S) Group A received letrozole (2.5 mg/d) for 12 weeks. Group B received triptorelin (3.75 mg/mo) for 12 weeks. MAIN OUTCOME MEASURE(S) Measurement of myoma volume and E(2), FSH, LH, and T levels. RESULT(S) Total myoma volume decreased by 45.6% in group A and 33.2% in group B. Reductions in myoma volume in the two groups were statistically significant. There was no significant change in hormonal milieu in group A. The serum level of hormones significantly decreased in group B by the 12th week of treatment. CONCLUSION(S) Uterine myoma volume was successfully reduced by use of an aromatase inhibitor. Rapid onset of action and avoidance of initial gonadotropin flare with an aromatase inhibitor may be advantageous for short-term management of women with myomas of any size who are to be managed transiently and who wish to avoid surgical intervention, specifically women with unexplained infertility having uterine myoma.

Pentoxifylline therapy after laparoscopic surgery for different stages of endometriosis: a prospective, double-blind, randomized, placebo-controlled study. J Minim Invasive Gynecol 2007; 14:54-8. [PMID: 17218230 DOI: 10.1016/j.jmig.2006.06.024] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2006] [Revised: 06/20/2006] [Accepted: 06/24/2006] [Indexed: 12/20/2022]
Abstract
STUDY OBJECTIVE To evaluate the effects of pentoxifylline administration on patients with different stages of endometriosis on whom laparoscopy was performed. DESIGN Prospective, double-blind, randomized, placebo-controlled clinical (Canadian Task Force classification I). SETTING University and private hospitals. PATIENTS Eighty-eight women, all with infertility, some with dysmenorrhea, dyspareunia, or pelvic pain, on whom a laparoscopic diagnosis of endometriosis was made. INTERVENTIONS The treatment group received 800 mg pentoxifylline daily for 6 months immediately after surgery. The control group received placebo capsules. All patients were followed-up for 1 year thereafter. MEASUREMENTS AND MAIN RESULTS A comparison of pregnancy rate and recurrence of signs and symptoms in the 2 groups was performed. Forty-three patients were studied in the pentoxifylline group and 45 in the placebo group. The cumulative pregnancy rate was 39.5% and 35.6% in the treatment and control groups, respectively. The overall recurrence of signs and symptoms was 14% in the former group and 15.6% in the latter. There were no statistically significant differences between the 2 groups in rates of pregnancy and recurrence (p = .700 and .832, respectively). Nor was there any significant statistical difference between the same stages in the 2 groups regarding immunomodulation. CONCLUSIONS According to the results of this study, and while keeping in mind that appropriate surgery is the main aspect of endometriosis treatment, there is no evidence that immunomodulation with pentoxifylline aids fertility or lessens recurrence of signs and symptoms in women with different stages of endometriosis (i.e., minimal, mild, moderate, or severe).

Abstract
OBJECTIVES To compare the accuracy of saline infusion sonohysterography (SIS) with transvaginal sonography (TVS) for the screening of causes of abnormal uterine bleeding (AUB) in out-patients. METHODS 81 patients with AUB were studied. All cases who were examined with TVS, were further investigated with SIS using saline as contrast medium, finally hysteroscopy was used as the gold standard. RESULTS TVS had sensitivity of 72%, specificity of 92%, positive predictive value of 94% and negative predictive value of 65%, while SIS had sensitivity of 94.1%, specificity of 95%, positive predictive value of 96% and negative predictive value of 90%. TVS had kappa measure of agreement of 0.60 while 0.86 was reported for SIS. CONCLUSIONS In this study SIS was more sensitive and specific in diagnosing polyp, myoma and adenomyosis with high positive and negative predictive value. Furthermore, results obtained by SIS demonstrate more agreement with that obtained by hysteroscopy than TVS.

Abstract
OBJECTIVE To determine if sectioning of the cervical septum in hysteroscopic metroplasty of the complete uterine septum is associated with intraoperative bleeding, cervical incompetence, and secondary infertility. DESIGN Multicenter, randomized, controlled clinical trial. SETTING University hospitals. PATIENT(S) Twenty-eight women with a diagnosis of complete uterine septum who had a history of pregnancy wastage or infertility. They were randomized into two groups: group A underwent metroplasty including section of the cervical septum; group B underwent the same procedure with preservation of the cervical septum. INTERVENTION(S) Hysteroscopic metroplasty was performed for all patients in the two groups. MAIN OUTCOME MEASURE(S) Operating time, distending media deficit, total distending media used, intraoperative bleeding, complications, and reproductive outcome. RESULT(S) Operating times were 36.40 +/- 10.67 minutes and 73 +/- 14.40 minutes in group A and group B, respectively. Distending media deficit was 456.66 +/- 165.68 mL in group A, while in group B it was 673.84 +/- 220.36. Two cases of pulmonary edema and three cases of significant bleeding (> 150 mL) were seen in group B. The cesarean section rate was significantly higher in group B. There were no significant differences in the reproductive outcome in the two groups. CONCLUSION(S) Resection of the cervical septum during hysteroscopic metroplasty of complete uterine septum makes the procedure safer, easier, and less complicated than the procedure with preservation of the cervical septum. This procedure is recommended for all cases of complete uterine septum.

Abstract
OBJECTIVE To evaluate the efficacy of a peritoneal graft for the treatment of cervical aplasia. METHOD Four patients with cervical aplasia who had a functioning endometrium and hematometra were recruited for this clinical trial. Through an abdominoperineal approach a plastic stent was inserted between the endometrial cavity and the upper part of the vagina; then, a graft of peritoneum was applied over the stent. In the absence of a vagina, grafts of skin or amniotic membrane were also used. The plastic stent was removed after 1 month in 2 patients and after 1 week in the 2 other patients. RESULT After more than 1 year of observation the 4 patients had regular menstrual cycles with normal menstruation. Sonographic examinations also showed empty uterine cavities. CONCLUSION Traditional gynecology textbooks recommend hysterectomy in cases of cervical aplasia. This report presents a new technique with 2 variations using a peritoneal graft. Although both variations were successful in the treatment of cervical aplasia in 4 women, more trials are needed to determine which one should be developed.

Abstract
OBJECTIVE To determine the difference between two laparoscopic methods for the management of endometriomas with regard to recurrence of signs and symptoms and pregnancy rate. DESIGN Prospective, randomized clinical trial. SETTING Infertility and gynecologic endoscopy units of two medical university hospitals. PATIENT(S) One hundred patients with endometriomas who had either infertility or pelvic pain. INTERVENTION(S) Patients were randomly divided into two groups; one group underwent cystectomy (group 1), and fenestration and coagulation were performed for the other (group 2). MAIN OUTCOME MEASURE(S) A comparison of recurrence of signs and symptoms of endometriomas and pregnancy rates in two groups. RESULT(S) Fifty-two patients were studied in group 1 and 48 in group 2. The recurrence of symptoms, such as pelvic pain and dysmenorrhea, was 15.8% in group 1 and 56.7% in group 2 after 2 years. The rate of reoperation was 5.8% in group 1 and 22.9% in group 2 and these differences were statistically significant. The cumulative pregnancy rate was significantly higher in group 1 (59.4%) than in group 2 (23.3%) at 1-year follow-up. CONCLUSION(S) Laparoscopic cystectomy of endometriomas is a better choice than fenestration and coagulation because the former technique leads to a lower recurrence of signs and symptoms and a lower rate of reoperation and a higher cumulative pregnancy rate than the latter.

Abstract
OBJECTIVE The purpose of this study was to examine the effects of of bromocriptin combined with clomiphene citrate in clomiphene-resistant patients with polycystic ovary syndrome and normal prolactin level. DESIGN Prospective, double-blind, controlled study. SETTING University teaching hospital. PATIENTS One hundred polycystic ovary patients and normal prolactin (PRL) who were clomiphene citrate resistant. INTERVENTIONS Treatment group received 150 mg clomiphene citrate on days 5-9 and 7.5 mg bromocriptin continuously. Control group received the same protocol of clomiphene citrate combined with placebo. MAIN OUTCOME MEASURES Hormonal status, follicular monitoring, ovulation rate. RESULTS Follicular development (follicular size greater than 15 mm) was observed in 12 (25.5%) and eight (15.1%) women in treatment and placebo group respectively ( P=0.29). The serum prolactin level was within normal limits in all patients before treatment. After 3 and 6 months of treatment with bromocriptin, there was a significant decrease in serum level of prolactin ( P=0.000001). No any significant differences was seen in ovulation, and serum levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEAS), progesterone (P) between treatment and placebo group after treatment. CONCLUSIONS The only significant effect of long-term bromocriptin therapy in clomiphene citrate resistant polycystic ovary women was to lower the serum prolactin concentration. It was also concluded that 10-15% of patients with polycystic ovaries experienced occasional ovulatory cycles and pregnancy whether or not they were on treatment.

Abstract
OBJECTIVE To evaluate the role of ketoconazole in prevention of ovarian hyperstimulation syndrome (OHSS) in women with the polycystic ovary syndrome (PCOS) undergoing ovarian stimulation with gonadotropins. DESIGN Prospective, randomized, double-blind, placebo-controlled study. SETTING University hospitals. One hundred nine women with PCOS who were referred for treatment with gonadotropins. INTERVENTION(S) Fifty patients were randomly assigned to receive two ampoules of hMG beginning on day 2 or 3 of the cycle and ketoconazole (50 mg every 48 hours) starting on the first day of hMG treatment. Fifty-one patients received the same amount of hMG plus one tablet of placebo every 48 hours. MAIN OUTCOME MEASURE(S) Follicular development, E(2) level, and pregnancy rate. RESULT(S) The total number of hMG ampoules and duration of treatment to attain ovarian stimulation were higher among ketoconazole recipients. The serum E(2) level and number of patients with dominant follicles on day 9 of the cycle were greater in placebo recipients. Serum E(2) level and total number of follicles at the time of hCG administration did not differ between the two groups. The cancellation rate and OHSS rate were similar in the two groups. CONCLUSION(S) Ketoconazole does not prevent OHSS in patients with PCOS who are undergoing ovarian stimulation. It may reduce the rate of folliculogenesis and steroidogenesis.

Abstract
STUDY OBJECTIVE To compare the effect of intraperitoneal bupivacaine and lidocaine on reducing pain after diagnostic laparoscopy. DESIGN Randomized, double-blind, placebo-controlled study (Canadian Task Force classification I). SETTING University teaching hospital. PATIENTS One hundred thirty-four women with unexplained infertility. INTERVENTION Diagnostic laparoscopy with intraperitoneal administration of bupivacaine or lidocaine. MEASUREMENTS AND MAIN RESULTS Patients were randomized into one of four groups. In group A, at the end of laparoscopy 0.125% bupivacaine 30 ml was instilled into the pelvic cavity and the same dose was instilled over the diaphragmatic vault. Groups B and C received the same volume of 5% lidocaine and normal saline, respectively. Group D received no intraperitoneal agent. The verbal pain scale questionnaire was used to assess postoperative pain. Pain scores 2 and 24 hours postoperatively were significantly lower for group A than for groups B and C (p = 0.0001). Scores in group B were also significantly lower than those in groups C and D (p = 0.0001). Women in group A required less additional analgesia than those in the other groups. CONCLUSION Compared with lidocaine and placebo, intraperitoneal bupivacaine significantly decreased postoperative pain, and this effect was long lasting.

Abstract
BACKGROUND Women with PCOS have significant differences in intra-ovarian and uterine artery haemodynamics. The aims of this study were to compare the ovarian stromal blood flow before and after laparoscopic ovarian diathermy, and to evaluate the value of these parameters in predicting the outcome of treatment in women with polycystic ovaries. METHODS Colour Doppler blood flow within the ovarian stroma was recorded and serum concentrations of FSH, LH and testosterone were measured in 52 women with polycystic ovaries before and after laparoscopic ovarian diathermy. Ovulation was evaluated by folliculometry and progesterone assay in the first menstrual cycle after operation. RESULTS Six to 10 weeks after the diathermy, serum concentrations of LH and testosterone decreased significantly (P = 0.001). The mean +/- SD peak systolic velocity decreased from 14.04 +/- 6.28 to 12.49 +/- 6.32 cm/s (P = 0.001), pulsatility index increased from 0.98 +/- 0.36 to 1.78 +/- 0.72 (P = 0.001), and resistance index increased from 0.55 +/- 0.16 to 0.71 +/- 19 (P = 0.001). A total of 73% of the women ovulated. There were significant negative correlations between pulsatility index and LH (r = -0.43, P = 0.001), pulsatility index and testosterone (r = -0.40, P = 0.003) and pulsatility index and LH/FSH ratio (r = -0.53, P = 0.001). CONCLUSIONS Laparoscopic ovarian diathermy in women with polycystic ovary syndrome may result in a decrease in ovarian stromal blood flow velocity. There was a significant correlation between hormonal and ovarian stromal blood-flow changes. Changes in the Doppler parameters were significantly higher in women who ovulated. The measurement of ovarian stromal blood flow by colour Doppler may be of value in predicting the outcome of treatment.

Abstract
OBJECTIVE To study the effect of clomiphene citrate (CC) on the thickness and echogenic pattern of the endometrium using vaginal sonography. METHOD In this experimental prospective study, CC was given to 31 women with unexplained infertility. Thickness and echo patterns of the endometrium, as well as estradiol (E2) and progesterone (P) levels, were compared in women taking CC and in control patients during both the late proliferative and midsecretory phases of the menstrual cycle. RESULTS Endometrial thickness was significantly thinner in women taking CC (P<0.03) than in controls during the late proliferative phase but there was no significant difference during the midsecretory phase. The endometrial echogenic patterns of women taking CC who had conceived revealed endometrial thicknesses of grade III and grade IV on midsecretory days, but these findings were not significantly different from those of women who had not conceived (P=0.3). Serum E2 level was higher in women taking CC than in the controls on both late proliferative and midsecretory days (P<0.05). CONCLUSION CC affects endometrium thickness on late proliferative days but not on midsecretory days, and does not alter the echogenic pattern of the endometrium.

Abstract
OBJECTIVE To evaluate the effects of short-course administration of dexamethasone (DEX) combined with clomiphene citrate (CC) in CC-resistant patients with polycystic ovary syndrome (PCOS) and normal DHEAS levels. DESIGN Prospective, double-blind, placebo-controlled, randomized study. SETTING Referral university hospitals. PATIENT(S) Two hundred thirty women with PCOS and normal DHEAS who failed to ovulate after a routine protocol of CC. INTERVENTION(S) The treatment group received 200 mg of CC from day 5 to day 9 and 2 mg of DEX from day 5 to day 14 of the menstrual cycle. The control group received the same protocol of CC combined with placebo. MAIN OUTCOME MEASURE(S) Follicular development, hormonal status, ovulation rate, pregnancy rate. RESULT(S) Mean follicular diameters were 18.4124 +/- 2.4314 mm and 13.8585 +/- 2.0722 mm for the treatment and control groups, respectively. Eighty-eight percent of the treatment group and 20% of the control group had evidence of ovulation. The difference in the cumulative pregnancy rate in the treatment and control groups was statistically significant. CONCLUSION(S) Hormonal levels, follicular development, and cumulative pregnancy rates improved with the addition of DEX to CC in CC-resistant patients with PCOS and normal DHEAS. This regimen is recommended before any gonadotropin therapy or surgical intervention.

Abstract
OBJECTIVE To evaluate the effects of administration of bromocriptine combined with clomiphene citrate (CC) in CC-resistant patients with polycystic ovary syndrome (PCOS) and normal prolactin (PRL) level. DESIGN Prospective double-blind, placebo-controlled, randomized. SETTING Referral university hospitals. PATIENTS One hundred women with PCOS and normal PRL who failed to ovulate with a routine protocol of CC. INTERVENTIONS Treatment group received 150 mg of CC from day 5 to 9 and 7.5 mg bromocriptine continuously, with hCG 10,000 units on day 16 or 17. Control group received the same protocol of CC combined with placebo. MAIN OUTCOME MEASURES Follicular development, hormonal changes, ovulation rate, pregnancy rate. RESULTS Follicular development (follicular size greater than 15 mm) was observed in 12 (25.5%) and 8 (15.1%) women in the treatment and placebo group, respectively (p = 0.29). The serum prolactin level was within normal limits in all patients before treatment. After 3 and 6 months of treatment with bromocriptine, there was a significant decrease in serum level of prolactin (p = 0.000001). No significant differences were seen in ovulation, pregnancy rate, or serum levels of FSH, LH, DHEAS, and progesterone between treatment and placebo groups after treatment. CONCLUSIONS The only significant effect of long-term bromocriptine therapy in CC-resistant women with PCOS was to lower the serum PRL concentration. It is also concluded that 10%-15% of patients with PCOS experienced occasional ovulatory cycles and pregnancy whether or not they were on treatment.

Abstract
OBJECTIVES This study was performed to evaluate the rate of diagnosed female genital tuberculosis and its presentational symptoms and methods of diagnosis. METHODS A total of 3088 cases of tuberculosis (TB) who had been registered and treated in the Health Center of Fars Province from 1989 to 1999 were retrospectively studied. From this group, 46 women were diagnosed as having genital TB. The diagnosis in 41 cases was based on the standard pathological criteria of tissue specimens. The other five cases were excluded from this study due to the lack of classical diagnostic criteria. Statistical analysis was performed using the Z-test. RESULTS The mean age of the patients at the time of diagnosis was 30.4 years. Seven patients presented with abdominal or pelvic pain (17.07%). In this group three cases underwent laparatomy due to abdominal mass and four patients for tubo-ovarian abscess, which led to the diagnosis. Abnormal uterine bleeding was the cause of diagnostic dilatation and curettage in three other patients (7.31%). However, in 31 cases (75.6%) TB was diagnosed during studies performed to evaluate the cause of their infertility, and the most common diagnostic procedure was endometrial curettage (25 cases). Female genital TB accounted for 1.32% of all tuberculous patients in this study. Of these, 75.6% were infertile by definition (Z=12.13 P<0.0001). TB endometritis was detected in 72.03%, tubal involvement in 34.03%, ovarian TB in 12.9% and cervical TB in 2.4% of the patients. CONCLUSIONS This study confirms the presence of a strong relationship between genital TB and infertility; therefore genital TB would be more frequently diagnosed if this possibility was considered in the evaluation of every infertile patient in areas where tuberculosis is endemic.

Abstract
OBJECTIVES To evaluate the clinical features, endocrine and metabolic profiles in clomiphene (CC) responders and non-responders with polycystic ovarian disease (PCOD), and to examine the effects of metformin (MTF) on the above parameters of CC resistance. METHODS A prospective clinical trial was undertaken at the infertility division of a university teaching hospital. Forty-one CC responders were selected and their hormonal and clinical features were determined. Forty-one CC-resistant PCOD women were also selected and clinical features; metabolic and hormonal profiles before and after treatment with MTF 1500 mg/day for 6-8 weeks were evaluated. Women who failed to conceive were treated by CC while continuing to take MTF. RESULTS CC responders had higher insulin levels while non-responders were hyperinsulinemic. Menstrual irregularities improved in 30%. Mean+/-S.D. area under curve of insulin decreased from 297.58+/-191.33 to 206+/-0.1 mIU/ml per min (P=0.005). Only 39.39% ovulated and 24.24% conceived. CONCLUSION PCOD is associated with insulin resistance (IR) particularly in CC-resistant women. Insulin resistance and androgen levels are significantly higher in obese patients. MTF therapy improved hyperandrogenemia, IR, and pregnancy rate.
