sex, genetics & genomics

The largest study of its kind to date estimates that genetics accounts for at most 8–25 percent of variation in whether or not a person reports engaging in non-heterosexual behaviors.

Scientists found they could sort mouse sperm prior to IVF by treating semen with a drug that selectively slows down X-bearing cells.

The government wants to limit a person’s sex to male or female as determined by genitalia at birth and genetics. It’s not so simple, say scientists.

Researchers believe the genetic locus affects the regulation of another gene involved in sexual function.

Cross-species trysts likely spread human papillomavirus (HPV) to Homo sapiens, according to new research.

Two sequencing studies reveal the genetics underlying the sexual behavior of the European and Asian birds.

Female fruit flies challenged with infection during their lifetimes have offspring with greater genetic diversity.

Scientists who study the biological roots of sexual orientation should continue working with educators, policy-makers, and the public to put their data to good use.

Researching the causes of sexual orientation should be guided by scientific, not social, concerns.
