Funded Activity Summary

It has been recently found that some factors during intrauterine life are important and previously unsuspected determinants of cardiovascular disease decades later. The mechanisms are not yet clear but placental function in maintaining fetal nutrition and hormone secretion are likely to be important. Similar mechanisms have been found to affect female reproductive function and non-reproductive hormones in humans but the potential effects involving male reproductive health have not been studied so far. This project aims to search for prenatal factors that affect the development of the testis and prostate. By this means, prenatal factors may be an important in determining susceptibility to male infertility by lowering sperm output, androgen deficiency due to diminished testicular testosterone secretion and prostate disease notably prostatic hyperplasia. In this study we will employ our own specialised techniques for highly accurate measurement of the size of prostate zones and the testis using high frequency ultrasound. We will identify a birth cohort - a group of men born in a single hospital around 1970 - in whom we will measure prostate zones and testis size by ultrasound together with the hormonal markers relevant to the testis and prostate to examine whether any changes seen according to birthweight are due to concordant changes in hormones. This study could change the way in which disorders of male reproductive health are considered by focusing on factors occurring before and shortly after birth rather than on genetic or ambient environmntal factors in adult life which have been the overwhelming focus of research over recent decades.
