Is she a he? Depends

The South African athlete will be assessed and tested by a group of doctors, including an endocrinologist, a gynaecologist, an internal medicine expert, an expert on gender and a psychologist.

They will look at her external genitalia, but they will also look at hormone levels and her chromosomal make-up.

There are also particular conditions they will check for, including congenital adrenal hyperplasia.

This is a condition in which the body produces more androgen, a type of male hormone.

If a girl has it, they will usually have normal internal female reproductive organs, but may not have periods and may have a male appearance.
