Spermatozoa are rarely present; 1 however, ostensibly normal oocytes may exist even in ovotestes. Prevalences of bicornuate and unicornuate uteri seem likely to be underestimated, since the uterus was often not completely described. That ovarian tissue is often normal is also evidenced by breast development, cyclic menses, and histologic evidence of ovulation.
Thus, different tribal ancestry may exist. The possibility of chimerism has not been excluded, however, or even, in most cases, vigorously pursued. In older individuals the accepted gender may be reinforced by the appropriate surgical procedures and by hormonal therapy.

A testis or an ovotestis is more likely to be present on the right than on the left. Ovotestes are the predominant gonadal form in South Africa and these were almost always pelvic in location. The ovarian portion contains not only stroma but also oocytes.
