title: Local antifertility effect of luteinizing hormone-releasing hormone (LRH).
abstract: Injection of luteinizing hormone-releasing hormone (LRH) into the right uterine horn of the rat on D5 produced a dose related inhibition of pregnancy in the treated horn. The number of viable fetuses as well as the uterine weight was reduced while the number of placental sites was increased. The contralateral uninjected horn was unaffected. These data demonstrate that LRH can inhibit pregnancy in the rat through an extrapituitary effect.
