OBJECTIVE Several publications have established a relationship between sperm DNA damage and male factor infertility, based on data from America, Europe, and Asia. This study aimed to compare the extent of sperm DNA damage in sperm samples from Nigerian men with unexplained infertility and in sperm samples from a fertile group composed of sperm donors who had successfully impregnated a female pa...
OBJECTIVE Growing evidence suggests that increased cardiovascular disease (CVD) risk is associated with female infertility caused by conditions such as polycystic ovarian disease, obesity, thyroid dysfunction, and endometriosis. The aim of this study was to evaluate whether any relationship exists between CVD and unexplained infertility. METHODS Sixty-five women with unexplained infertility a...
background: auto antibodies to zona-pellucida (aza) seem to be important autoantibodies implicated in reproduction, with substantial role in both endocrine and reproductive functions of the human ovary. there are some debates on the relation of aza with infertility, repeated in vitro fertilization (ivf) attempts, and outcome of it. objective: in this study, we assessed the presence of aza in th...
This study aims to determine the relative contribution of oocyte and/or sperm dysfunction to the reduction of fertilization rates in vitro in cases of minor endometriosis and prolonged unexplained infertility. The results of in-vitro fertilization (IVF) treatment with ovarian stimulation have been compared between couples with the above conditions and women with tubal infertility (as control fo...
Abstract: Background and Aim: The increasing incidence of infertility is alarming. About 10-30% of infertility are classified as Unexplained Infertility (UI) which is not an absolute clinical condition. TGF-b1 is multifunctional cytokine and produced mainly by T regulatory (Treg) lymphocytes. This cytokine plays important roles in physiology of normal pregnancy. The association of Single...
Received: 11 June, 2008 Accepted: 21 Jan, 2009 Abstract Background & Aims : Infertility affects approximately 10-15% of couples. The major causes of infertility include ovulatory dysfunction, tubal and peritoneal pathology, uterine pathology and male factors. Unexplained infertility is 10-15% of cases of infertility. Ovarian stimulation combined with IUI is treatment of couples with male fa...
The study of sperm cellular components at molecular level is crucial for the diagnosis of male unexplained infertility. The aim of the study was to compare the molecular profile of steroid receptors and aromatase in spermatozoa obtained from two normozoospermic groups of patients issued from couples treated for infertility. We investigated 46 male patients from unexplained infertility couples a...
BACKGROUND Increased maternal and fetal risks have been reported in pregnancies following unexplained infertility. Our aims were to examine the obstetric and perinatal outcome of singleton pregnancies in couples with unexplained infertility and explore the impact of fertility treatment. METHODS Women with unexplained infertility were identified from the Aberdeen Fertility Clinic Database. The...
Background Failure in the endometrial receptivity may account for a significant number of infertility cases including unexplained infertility in women. Reduction in the endometrial estrogen receptor-alpha (ER-α) expression during implantation may be a critical event that coincides with the expression of specific genes and the formation of a receptive endometrium. The aim of the present study wa...
