The external genitalia of a developing fetus become distinguishable as male or female during the fetal stage of development. This typically occurs around the 9th to 12th week of gestation. During this stage, the male and female external genitalia begin to differentiate based on the presence or absence of certain hormones and genetic factors, leading to the development of either male or female reproductive organs.
