Human Andrology 2011, 1:2–16 Objective To highlight the concept of unexplained male infertility and discuss the potential causes and its proper management. Design Review of literature. Results Male infertility of unknown origin is a condition in which fertility impairment occurs spontaneously or due to an obscure or unknown cause. It includes two categories, unexplained male infertility and idi...

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...

It is estimated that the male factor contributes to half of the infertility in couples attending for assisted reproductive techniques (ART). Therefore the semen analysis remains the starting point to evaluate main causes of infertility and in case of oligospermic semen the assessment of sperm morphology may help to choose the best spermatozoon to use for the intracytoplasmic sperm injection (IC...

About infertility Infertility is the inability of a couple to get pregnant despite having regular unprotected sex. A couple is regarded as infertile if, after regular sexual intercourse, they have not conceived in two years. It is estimated that one in seven UK couples has difficulty conceiving (HFEA, 2006). Identifiable causes of infertility include: ovulatory disorders in 27% of couples; tuba...

IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF. Extremely low sperm counts, impaired motility and/or abnormal m...

Objective The primary objective of the study was to compare baseline KP levels in females with different causes of infertility and then correlate it with the risk of failure to conceive, preclinical abortion and pregnancy after intracytoplasmic sperm injection (ICSI). MaterialsAndMethods AA longitudinal cohort study was carried out from August 2014 till May 2015 recruiting one hundred and twent...

The test is cost-effective and easy to perform and at the same time provides essential information on quantitative semen parameters such as semen volume, sperm motility, concentration, viability and morpholo...

background: the purpose of this study was to evaluate the prognostic effect of hyaluronan binding assay (hba) which has been used as a method of sperm selection for intracytoplasmic sperm injection procedure, on the outcome of intrauterine insemination (iui) in couples with unexplained or mild male factor infertility. methods: 77 infertile couples were enrolled in our study. on the day of iui p...

Semen analysis (SA) is the cornerstone for male infertility evaluation. Variations in sperm quantity and quality may make SA an unreliable decision-making tool in providing an insight of infertility (1). Consequently, efforts have been made to upgrade techniques of male fertility analysis. In recent times, primary investigative techniques have centered around assessing sperm capacity, sperm fun...

BACKGROUND Kisspeptin (KP) is a neuropeptide that causes the release of the gonadotropin releasing hormone, which controls hypothalamo pituitary ovarian axis and exerts a number of peripheral effects on reproductive organs. The primary objective of this study was to compare baseline KP levels in females with different types of infertility and identify possible correlations with risk of failure ...
