Policies to address the sexual and reproductive health and rights (SRHR) are vital, especially in lower middle and middle-income countries (LMICs). Hence, the aim of this study was to compare the national infertility policies in the selected countries (LMICs comparing with high-income) to determine gaps or to confirm desirable policies in the given health systems.

The purpose of this study was to determine the pregnancy rate in the double sequential transfer of embryos on both day 3 and day 5 compared to day 5 alone, in fertilization-embryo transfer (IVF/ET) in patients with the three repeated consecutive IVF failures. In this controlled trial, women scheduled for IVF/ET with the three repeated consecutive IVF failures were randomized to either sequential transfer of embryos on day 2 and on day 5 after ovum pick-up (group 1, = 60) or blastocyst ET on day 5 (group 2, = 60) as a control group. The primary outcome measures were the chemical and clinical pregnancy rate.

In the current study we assess the role of vascular endothelial growth factor (VEGF) - 2578 A/C, and + 936 C/T polymorphisms in susceptibility to endometriosis and checking the expression of VEGF mRNA in eutopic tissue of endometrium with and without endometriosis. The study was comprised of 300 patients who underwent laparascopic or laparotomy surgery with 100 cases who had confirmed histological diagnosis of endometriosis, and 200 controls with no histological diagnosis of disease.

In fact, reactive oxygen species (ROS), especially superoxide anion (O·) and hydrogen peroxide (HO), play a crucial role in regulation of physiological and pathological processes in spermatozoa.
View Article and Find Full Text PDFBackground: Endometriosis is a multifactorial hormonally related complex disease with unknown etiology. Epidemiologic data were suggested the possible effects of endocrine disrupting chemicals such as bisphenol A (BPA) on endometriosis. BPA is similar to endogenous estrogen and has the ability to interact with estrogen receptors and stimulate estrogen production.

The objective of this study was to evaluate the association between Polychlorinated Biphenyls (PCBs) and Polybrominated Diphenyl Ethers (PBDEs) as POPs with pre-eclampsia.
Methods: This case-control study was performed in the three general university hospitals of Tehran University of Medical Sciences.
Background: There is growing evidence that persistent organic pollutants (POPs) may play an important role in increasing the risk of gestational diabetes mellitus (GDM).
Objectives: The aim of this study was to examine the association between polychlorinated biphenyls (PCBs, 10 congeners) and polybrominated diphenyl ethers (PBDEs, 8 congeners) and GDM in primiparous women with no family history of diabetes in first-degree relatives during the third trimester of pregnancy.
Methods: This case-control study was performed among the three university hospitals of Tehran University of Medical Sciences.
Objective: To compare serum anti-Müllerian hormone (AMH) and other endocrine parameters between patients diagnosed with polycystic ovary syndrome (PCOS) and age-matched ovulatory women.
Materials And Methods: AMH, DHEAS, FSH, LH, PRL, TSH and total testosterone (TT) were prospectively measured in oligo-ovulatory PCOS patients (n = 595) and in ovulatory non-PCOS women (n = 157) referred to a tertiary infertility center. Mean BMI was similar across the two study populations and there were no smokers in the sample.
Purpose: To determine the level of apoptosis, and alteration of FoxO3 (forkhead box O3 transcription factor) expression and phosphorylation in human granulosa cells amongst polycystic ovary syndrome (PCOS) patients and control group.
Methods: We recruited infertile women with PCOS (n = 14) and compared them with infertile women due to tubal blockage or male factor infertility (n = 14, controls). GnRH agonist and gonadotropins were used for ovarian stimulation.

Background/objectives: Insulin resistance (IR) is a main pathophysiologic feature in polycystic ovary syndrome (PCOS) patients which is triggered by elevated oxidative stress in these patients. Selenium, an essential micronutrient, is a major constituent of antioxidant enzymes such as glutathione peroxidase. Recently, decreased plasma selenium concentrations were reported in PCOS patients.

Material And Methods: A total of 301 eligible Iranian women were studied. In this double-blinded trial, data were analyzed from 3-day urinary diaries from before and after 12 weeks of treatment in which patients were randomly assigned to receive oxybutynin or tolterodine in recommended doses.

Background: Nowadays, Chlamydia trachomatis is known as a causative agent of infertility. Because of, asymptomatic nature of infection, many may suffer from its lasting complications such as infertility. This study was performed in Tehran during April 2007 to April 2008 to compare the prevalence of Chlamydia trachomatis infection in fertile and infertile women using ELISA and PCR methods.
View Article and Find Full Text PDFBackground: Different mechanisms have been described for the effects of acupuncture on fertility. Acupuncture may mediate neurotransmitter release, which results in the stimulation of gonadotrophin-releasing hormone secretion. The production of neurotransmitters such as endogenous opioids may also inhibit central nervous system outflow and biological stress response.

Methods: In this study we used the RAM criteria. In order to prepare the list of cesarean scenarios, clinical guidelines were selected, and the Appraisal of Guidelines for Research and Evaluation was used to choose the most appropriate.
Objective: The aim of our study was to investigate the frequency and compare the prevalence of IRS-1Gly972Arg and IRS-2 Gly1057Asp polymorphisms in PCOS patients and non-diabetic healthy women. MATERIAL(S) AND METHOD(S): Forty eight Iranian women diagnosed with PCOS were enrolled in this study. Fifty two non-diabetics, non-PCOS women were enrolled as the control group.
View Article and Find Full Text PDFBackground: The differential efficacy between long GnRH agonist with antagonist can partly be due to the preexisting differences in the early antral follicles before ovarian stimulation.
Objective: To compare the effect of pretreatment by estradiol with GnRH antagonist on antral follicular size coordination and basal hormone levels in GNRH antagonist protocol.
Materials And Methods: On cycle day 3 (control/day 3), women underwent measurements of early antral follicles by ultrasound and serum FSH and ovarian hormones then were randomized to receive oral estradiol 4mg/day (n=15) or 3mg cetrorelix acetate (n=15) in luteal phase before subsequent antagonist protocol.
Background: General concern is that the pregnancy rate is higher with GnRH-agonist as a protocol of pituitary suppression. GnRH-antagonist protocol provides a shorter period of administration and an easy flexible protocol.
Objective: In this study, the outcomes of GnRH agonist and antagonist in ICSI cycles are compared in normo responder patients.
Objective: To evaluate effects of simvastatin on selected biochemical parameters and reproductive outcome among patients with polycystic ovary syndrome (PCOS) who undergo in vitro fertilization (IVF).
Methods: Patients with PCOS were randomized to receive either oral simvastatin, 20 mg/d (n = 32), or placebo (n = 32) in a prospective, double-blind, randomized clinical trial (NCT 005-75601) in parallel with controlled ovarian hyperstimulation for IVF. All patients were determined to be at average risk for cardiovascular disease, based on high-sensitivity C-reactive protein (hsCRP) measurement at entry.
