STUDY QUESTION How many infertile men who wish to conceive need to be screened for chromosomal abnormalities to prevent one miscarriage or the birth of one child with congenital anomalies (CAs)? SUMMARY ANSWER In azoospermic men, the prevalence of chromosomal abnormalities is 15.2% and the number needed to be screened (NNS; minimum-maximum estimate) for a miscarriage is 80-88 and for a child ...

The presence of various cytokines, namely the tumor necrosis factor (TNF-alpha), interferon (IFN-gamma), and interleukins (IL-1 beta and IL-6), was investigated in seminal plasma of fertile, infertile, and immunoinfertile men using specific immunoradiometric assays. TNF-alpha and IL-1 beta were not detected. IFN-gamma was detected, but the differences between the levels of fertile and infertile...

OBJECTIVE To compare the prevalence of sexually transmitted infections (STIs) (including HIV) and of high-risk sexual behaviour in the following three groups: primary infertile relationships, secondary infertile relationships and fertile relationships. Primary infertility is here defined as never having conceived before, secondary infertility as infertility subsequent to having conceived at lea...

OBJECTIVE The aim of this study was to determine the frequencies of Y chromosome microdeletions in infertile azoospermic and oligozoospermic Turkish men and in healthy control subjects. MATERIAL AND METHODS Sixty-four azoospermic and 51 oligozoospermic patients infertile patients, and 70 healthy men who had a child without the aid of assisted reproductive technologies were included in this st...

Objective Matrix Metalloproteinase (MMPs) play important roles in the structural and functional properties of reproductive organs. The aim of this study is to determine the prevalence of C-1562T Matrix Metalloproteinase-9 (rs3918242) gene polymorphism in fertile and infertile men. In addition, we aimed to determine the association between C-1562T MMP-9 and G-1575A MMP-2 gene polymorphisms. Mate...

background : approximately 15 percent of all the couples are involuntarily childless in reproductive ages. the ability to reproduce and give birth to a child is an important part of the human beings life; thus, infertility can cause anxiety for the infertile people. therefore, this study aimed to investigate men’s experiences from male infertility. methods : this was a descriptive phenomenologi...

The objective of the present study was to assess the ascorbic acid (AA) levels in seminal plasma of the fertile and infertile men and to investigate its relationship with sperm count, motility and normal morphology. Semen samples were provided by fertile [smoker (n = 25), nonsmoker (n = 21)] and infertile men [smoker (n = 23), nonsmoker (n = 32)]. A simplified method of reverse phase high perfo...
