Histological examination of gonad biopsies in case 1 revealed bilateral ovotestes. Histological examination of excised gonads in case 2 revealed features of an ovotestis with a gonadoblastoma and dysgerminomas in the left gonad and streak gonad parenchyma and PTH in the right gonad.
Freemartins have dysgenic testes or ovotestes, Wolffian-duct derivatives and female external genitalia frequently characterized by an enlarged clitoris.
individual is usually referred to as a "hermaphrodite." These persons are generally classified into three categories: true hermaphrodites, who have one or more ovotestes; female pseudohermaphrodites, who have ovaries and an XX chromosomal basis, but whose external genitalia look "masculinized" due to fetal exposure to high levels of androgens; or male pseudohermaphrodites, who have testes and an XY chromosomal pattern.
What we're finding in fish and birds and even mammals now are ovotestes, or testes that have ovarian tissue in them.
These male shrimps reproduce as males; however, the gonads are ovotestes with undeveloped ovaries.
This may take the form of one ovary and one testis or, more commonly, one or two ovotestes. Most patients with TH have ambiguous external genitalia, masculinized to variable degrees, although occasionally completely normal appearing mixed male and female genitalia have been reported.[sup.1] Overall, 75% of patients with TH are raised as male; in 80% of these, chordee, hypospadias and cryptorchidism can be seen.[sup.2,3] In the 25% raised as female, clitoromegaly can be present.

Ovotestes in this species contain ripe sperm and eggs simultaneously (Fig.
Gonadal feminization appeared to be progressive: some ovotestes were observed after 2- or 4-week exposure to the two highest doses, but the proportion of ovaries increased after 8 weeks.
