![Sex verification is not conducted on athletes competing in the male category, and little data are available on their chromosomes or hormone profiles. However, a post-competition study of 693 elite athletes by Healy et al., published in 2014, found significant differences along many variables. The authors found that:
16.5% of men had low testosterone levels, whereas 13.7% of women had high levels with complete overlap between the sexes.[73]
Using these data, Scientific American estimated that "almost 2 percent" of male competitors had testosterone levels in the typical female range.[74] The study authors also stated that average lean body mass differences might account for performance differences between sexes.[73]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:lbqxp2lr37gyxb55ik2gk7uf/bafkreico3wzzzrvujwf2vnxnghcynuouej3wxhkcau6wcerqghsmtaialu)
