maternal leukemia inhibitory factor (lif) is required for successful implanta¬tion in mice, but little is known about its role and expression in human reproduc¬tion. here we report on the pattern of lif mrna expression in 30 samples of previously fertile and 11 infertile human endometrium, 10 samples of previously fertile post-menopausal endometrium and 10 uterine (fallopian) tubes from pre¬vio...

OBJECTIVE To test the hypothesis that infertile Nigerian women have higher serum levels of antibodies against Neisseria gonorrhoea and Treponema pallidum compared with fertile controls. DESIGN The prevalence of serum antibodies against N gonorrhoea and T pallidum was compared in fertile and infertile Nigerian women. SETTING Population based case-control study in Ile-Ife, southwestern Nigeri...

Fertility reduction due to sub-fertile males is a major concern in breeder flocks. Phenotypic traits of broiler breeder males and their relationships with fertility can be used as reliable indicators for identification and removal of sub-fertile males from the breeder flocks. This study was conducted to investigate semen traits (semen volume, sperm motility, sperm viability and sperm count) and...

BACKGROUND This article analyzes several key issues in the debate: the acceptability of in vitro fertilization; regulation of assisted reproduction and the possibilities of reimbursement for assisted reproduction treatment in Lithuania. METHOD Two groups of respondents participated in the survey: fertile women and women with fertility disorders. 93 completed questionnaires from women with fer...

In the dominant mouse mutant Odd Sex, XXOds/+ mice develop as phenotypic, sterile males due to male-pattern expression of Sox9 in XXOds/+ embryonic gonads. To test whether SOX9 was sufficient to generate a fully fertile male in the absence of Sry, we constructed an XY(Sry(-))Ods/+ male mouse, in which the male phenotype is controlled autosomally by the Ods mutation. Mice were initially fertile,...

BACKGROUND A number of menstrual cycle monitors have been developed to detect the fertile window of the menstrual cycle, mainly for contraceptive purposes. Reliable data on most of these systems are still missing but are urgently needed because many women use them and the tested systems differ enormously in price and effectiveness. We suggest a new efficacy estimating method to evaluate cycle m...

Introduction: Our aim was to compare the nuclear DNA integrity of the spermatozoa from infertile men with abnormal semen parameters with that from normospermic fertile men, and to evaluate the relationship between the sperm DNA integrity and semen parameters. Materials and Methods: Thirty ejaculate samples with abnormal semen analysis and 30 ejaculates with normal semen parameters were randomly...

BACKGROUND/AIM About 10%-15% of couples around the world suffer from infertility. Male infertility is responsible directly or indirectly in approximately 60% of cases. A deficiency in semen is the most common cause of male infertility. MATERIALS AND METHODS The study included 180 male subjects aged 18-50 years with 26 fertile and 154 infertile. The infertile subjects were further subdivided a...
