OBJECTIVE To systematically evaluate the available literature regarding the relationship between assisted reproductive technology and ovarian cancer. DATA SOURCES Computerized search of 6 databases from 1966 (or closest) to present: Cochrane Controlled Trials Register, Cancerlit, CINHAL, Current Contents, PubMed in process (formerly called PreMEDLINE), and MEDLINE. We collected references fro...

The study examined the epidemiology and causes of infertility in Tomsk, Western Siberia, using methodological approaches recommended by WHO and was based on the findings for a randomly selected sample of 2000 married women aged 18-45 years. Among the respondents, 333 couples were considered infertile since they had not conceived after 12 months or more of unprotected intercourse. This group of ...

We analysed the CAG repeat length in exon 1 of the androgen receptor gene in 59 idiopathic Japanese infertile males with oligozoospermia; 36 fertile males were also analysed as controls. The number of CAG repeats in infertile males ranged from 14 to 32 (mean 21.2+/-4.2), whereas the number of CAG repeats in fertile males ranged from 16 to 31 (mean 21.4+/-3.5). Among infertile males, six possess...

The aim of this research was to determine the levels of human leukocyte antigen G (HLA-G) and endometrial Natural Killer ((e)NK) cell percentages in uterine flushing samples from primary and secondary infertile women. sHLA-G levels were lower in the uterine flushing samples from primary infertile women in comparison with women with secondary infertility. Lower CD56+KIR2DL4+ (e)NK cell percentag...

PROBLEM The objective of this study was to evaluate the contribution of chromosomal anomalies to decreased fertility in humans. METHOD OF STUDY In order to investigate the aetiology of infertility in our population and to assess the karyotype in a group of infertile couples and individuals with fertility problems, 782 persons (259 couples, 158 male and 106 female) with different clinical diag...

Background and Objectives: Unexplained infertility occurs in many couples of childbearing age, immune mechanisms have been postulated in this disorder for the last few decades. Circulating antibodies against spermatozoa present in serum and seminal plasma have been especially implicated. This autoimmunity against spermatozoa has been investigated in males, while the isoimmunity (in the females)...

BACKGROUND The aim of this study was to investigate the effect of chromosomal polymorphic variations on the outcome of IVF and embryo transfer (IVF-embryo transfer) treatment for infertile couples. METHODS During the period from October 2006 to December 2009, 1978 infertile couples who had received their first IVF-embryo transfer treatment cycle in our hospital were selected for this retrospect...

INTRODUCTION Elevated nitric oxide (NO) levels have been shown to have toxic effects on sperm function and motility. This study was conducted to compare NO levels in the seminal fluid of infertile men with varicocele with those of infertile and fertile men without varicocele. MATERIALS AND METHODS Semen samples were obtained from 40 infertile men with varicocele (group 1), 40 infertile men wi...

Reactive oxygen species (ROS) levels in semen are believed to play both physiological and pathological roles in male fertility. The study was aimed to find the clinical significance of ROS levels in infertile Indian men. This pilot study included 33 idiopathic infertile men and 18 proven fertile controls. ROS levels in the washed sperm were measured using chemiluminescence assay and expressed a...

BACKGROUND Infertility is a reproductive health problem and its prevalence is increasing in developing countries. This problem has some significant effects on the sexual behaviors of infertile women, especially during infertility treatment periods. Discovering the existing beliefs in the field of sexual and reproductive health and also determining the misconceptions would define the educational...
