Ambiguous genitalia is a birth defect where the outer genitals do not have the typical appearance of either a boy or a girl. The genetic sex of a child is determined at conception. The mother's egg cell contains an X chromosome , while the father's sperm cell contains either an X or a Y chromosome. These X and Y chromosomes determine the child's genetic sex. Normally, an infant inherits 1 pair of sex chromosomes, 1 X from the mother and 1 X or one Y from the father. The father "determines" the genetic sex of the child.
What causes an enlarged clitoris?
Ambiguous genitalia: MedlinePlus Medical Encyclopedia
Management of the enlarged clitoris, because of its import for sexual function, has been and remains one of the most controversial topics in pediatric urology. Early controversy surrounding clitoroplasty resulted from many factors including an incomplete understanding of clitoral anatomy and incorrect assumptions of the role of the clitoris in sexual function. With a better understanding of anatomy and function, procedures have evolved to preserve clitoral tissue, especially with respect to the neurovascular bundles. These changes have been made in an effort to preserve clitoral sensation and preserve orgasmic potential. It is the goal of this manuscript to describe the different procedures that have been developed for the surgical management of clitoromegally, with emphasis on the risks and benefits of each. Equally important to any discussion of such a sensitive topic is an understanding of long-term patient outcomes. As we will see, despite its importance, there has been a dearth of data in this regard.
Clitoral sizes and anogenital distances in term newborns in Nigeria
Metrics details. Previous studies suggest significant ethnic and racial differences in clitoral sizes and anogenital distances in the newborn. This study aimed to document normative data on clitoral sizes and anogenital distances of apparently normal term female infants in Sagamu. Interviewer-based questionnaire was applied to obtain sociodemographic data, pregnancy and birth history.
An eight-year-old girl presented with abnormal secondary sexual development. The patient had no notable medical history and was taking no medication. On examination, her breast development was classified as Tanner stage 1 and her pubic hair development as Tanner stage 3. She had an enlarged clitoris see accompanying figure and mild acne on her face.
