A 6-y-old female baboon was examined due to absence of menstrual cycling and secondary sex characteristics and failure to reproduce. The mammary glands and vaginal introitus were hypoplastic, the clitoris was prominent, and the perineal skin was immature with lack of cyclic color alterations and sexual swelling. Evaluation of the reproductive tract revealed a hypoplastic uterus and rudimentary ovaries with the presence of an ovarian leiomyoma within the right ovary. Hormonal values (estradiol, progesterone) were low and comparable to those of adult males or ovariectomized females. Adrenal and pituitary hormones (dehydroepiandrosterone, luteinizing and follicular stimulating hormones) and pituitary structure were within normal limits for this species. The baboon had a normal 42,XX karyotype. These findings suggest primary amenorrhea due to ovarian dysgenesis. This is the first report of a case of primary amenorrhea due to ovarian dysgenesis with a normal karyotype associated with a unilateral ovarian leiomyoma in the baboon. Continued studies of noncycling female nonhuman primates in captive breeding colonies may lead to a greater understanding of the underlying causes of this condition.

UI MeSH Term Description Entries
D007889 Leiomyoma A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.

D010051 Ovarian Neoplasms Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.

D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D005260 Female Females
D006059 Gonadal Dysgenesis A number of syndromes with defective gonadal developments such as streak GONADS and dysgenetic testes or ovaries. The spectrum of gonadal and sexual abnormalities is reflected in their varied sex chromosome (SEX CHROMOSOMES) constitution as shown by the karyotypes of 45,X monosomy (TURNER SYNDROME); 46,XX (GONADAL DYSGENESIS, 46XX); 46,XY (GONADAL DYSGENESIS, 46,XY); and sex chromosome MOSAICISM; (GONADAL DYSGENESIS, MIXED). Their phenotypes range from female, through ambiguous, to male. This concept includes gonadal agenesis. Gonadal Agenesis,Dysgenesis, Gonadal

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
