Paternity by Intrauterine Insemination with Sperm from a Man with 5α-Reductase-2 Deficiency

Male pseudohermaphroditism results from the abnormal differentiation of male external genitalia in a genotypic male. One cause of male pseudohermaphroditism is a deficiency of 5α-reductase-2, the enzyme that converts testosterone to 5α-dihydrotestosterone in specific androgen-dependent target tissues.1–3 Males who are homozygous for the disorder usually present with pseudovaginal perineoscrotal hypospadias at birth.
