Agonadism

HP:0008633

What it means

Absence of sex glands (gonads are the organs that produce gametes; testis in males and ovary in females).

Gonadal agenesis refers to the lack of development of gonads during fetal development; it may not be possible clinically to determine if gonal tissue was present at any point of development. For this reason, we regard agonadism and gonadal agenesis as synonymous.
