Posted Tue Nov 30 2010: from Environmental Health News:
Feminized male fish less likely to be fathers
Male fish feminized by exposure to environmental estrogens do not father as many offspring as their normal counterparts, suggesting the changes may alter wild fish populations. Male fish with a high degree of intersex produce fewer offspring when competing with normal males, according to a laboratory study that examined reproduction in intersex male fish - those with both male and female attributes. Although much is known about intersex fish, little is understood about how the condition affects the number of fish in the wild. This is an important question because the consequences of intersex become even greater if it leads to declines in fish population size.
