Effect of prenatal exposure to oestrogen on quality of semen: comparison of twins and singleton brothers

The decline in sperm count and increase in disorders of the male reproductive tract may be due to high concentrations of prenatal exposure to oestrogens.1-2 As the concentration of free oestrogens in plasma is much greater in twin pregnancies from the first weeks of gestation, and greater for dizygo...

Description
Summary:The decline in sperm count and increase in disorders of the male reproductive tract may be due to high concentrations of prenatal exposure to oestrogens.1-2 As the concentration of free oestrogens in plasma is much greater in twin pregnancies from the first weeks of gestation, and greater for dizygotic twins than monozygotic twins,3-4 we studied sperm count in twins and singleton brothers to see if twin brothers have lower sperm counts and if the lowest values are for dizygotic twins.
