background: although intrauterine insemination (iui) is one of the most common methods which is used for male factor and unexplained infertility the relative influence of various semen parameters on the likelihood of a successful outcome is controversial. several semen parameters have been evaluated as predictors of a successful outcome with intrauterine insemination. objective: to evaluate the...

BACKGROUND The conundrum of measuring condom use consistency, particularly with adolescents, has left researchers with a cacophony of strategies, thereby limiting comparability and interpretation. OBJECTIVE The aim of this analysis was to compare and contrast two measures of condom use consistency, global versus partner specific, and their relationships with key covariates, using trajectory g...

This paper describes the development of a theoretically based sex education programme currently undergoing a randomized controlled trial in the UK. It considers some of the practical difficulties involved in translating research-based conclusions into acceptable, replicable and potentially effective classroom lessons. The discussion acknowledges that the implications of social psychological res...

INTRODUCTION Male breast cancer accounts for 0.5-1% of all breast cancers and is generally diagnosed at higher stage than female breast cancers and therefore might benefit from earlier detection and targeted therapy. Except for HER2 and EGFR, little is known about expression of growth factor receptors in male breast cancer. We therefore investigated expression profiles of growth factor receptor...

IMPORTANCE Intracytoplasmic sperm injection (ICSI) is increasingly used in patients without severe male factor infertility without clear evidence of a benefit over conventional in vitro fertilization (IVF). OBJECTIVE To assess national trends and reproductive outcomes for fresh IVF cycles (embryos transferred without being frozen) following the use of ICSI compared with conventional IVF with ...

Background: Infertility is a multifactorial disorder affecting one in ten couples, and in 50% of infertile couples, the male factor due to deteriorated semen quality is a major cause. In about 30% of infertile men seeking help for their problem, the etiology and pathogenesis are not yet known and their condition is considered idiopathic. Through animal studies conducted recently, hundreds of ge...

BACKGROUND Intrauterine insemination (IUI) is one of the therapeutic approaches for infertility. The objective of this study was to evaluate DNA integrity and apoptosis role in success of IUI in both mild male and female factor infertility. METHODS PATIENTS WERE DIVIDED INTO TWO GROUPS: M (mild male factor; n = 29) and F (female factor; n = 31) undergoing single IUI. Ejaculates were analyzed ...

Fertilization, the fusion of male and female gametes, is an incompletely known, multistep, complex process, in which many factors participate. Fertilization is a precisely regulated, species-specific process, but some cellular mechanisms are similar for many mammal species. The studies of mechanisms of male and female gamete production enable understanding of fertilization issues and, as a resu...
