Washington, April 21 (ANI): Women with dominant nature have a higher likelihood of conceiving more sons, according to a new study.

The study report says that a growing body of evidence suggest a maternal influence on sex determination.

The study showed that the sex of bovine embryos positively correlates with pre-ovulatory follicular testosterone.

It, however, remains a mystery as to how exposure of oocytes to follicular testosterone may influence the ability of a metaphase II egg to be preferentially inseminated by a Y-bearing sperm.

The study has been published in the journal Biology of Reproduction. (ANI)
