Reproductive fitness is a complex phenotype that is a direct measure of Darwinian selection. Estimation of the genetic contribution to this phenotype in human populations is confounded by within-family correlations of sociocultural, economic, and other nongenetic factors that influence family sizes. Here, we report an intergenerational correlation in reproductive success in the Hutterites, a hu...

The foundation of a family is a personal enterprise with deep biological and emotional motivations. Family life is a no lesser priority for individuals living with HIV than for others. Moreover, the dramatic reduction in HIV-related morbidity and mortality as a consequence of the widespread use of HAART has led to a growing number of HIV-infected individuals and their partners requiring educati...

Exponential growth in genomics has led to public and private initiatives worldwide that have dramatically increased the number of procreative couples who are aware of their ability to transmit genetic disorders to their future children. Understanding how couples process the meaning of being genetically at-risk for their procreative life lags far behind the advances in genomic and reproductive s...

BACKGROUND It is often suggested that an effort must be made to increase awareness among consanguineous couples of their reproductive risk, and to refer them for genetic counseling if needed. Primary care professionals are considered most appropriate for addressing the subject and identifying couples at risk during consultations in their practice. This Dutch study aims to explore the experience...

Shortly after Dr. Ian Wilmut made international news in 1997 by announcing the successful cloning of an adult sheep, Chicago physicist Dr. Richard Seed made an announcement of his own that caused similar alarm. At a law school symposium on reproduction, the Harvard-educated physicist announced plans to perfect cloning procedures and then to open a human cloning clinic for infertile couples. At ...

Objective: The aim of this study was to evaluate the effects of aging on semen quality in a population of infertile couples. Methods: A cross-sectional study of semen samples obtained from 1,500 men randomly selected from couples who attended an infertility clinic was conducted. The analyses were performed using Spearman’s correlation and Mann-Whitney tests. The age groups consisted of men ≤ 35...

retrospective data from sebele dairy farm were analysed for reproductive performance of friesian/holstein cows. three hundred records from 1989 to 1995 were used. the herd was zero grazed and the data was analysed for age at first calving (afc), calf birth weights (bw), calving interval (ci), days open (do), calving rate (cr), reproductive wastage (rw) and calving difficulty (cd); dystocia, aft...
