Successful management of cervical pregnancy with medical intervention only: a case report.

Orthotopic transplantation of LH receptor knockout and wild-type ovaries.

Luteinizing hormone (LH) receptor knockout animals have an ovarian failure due to an arrest in folliculogenesis at the antral stage. As a result, the animals have an infertility phenotype. The present study was undertaken to determine whether this phenotype could be reversed by orthotopic transplantation of wild-type ovaries.

A case of gonadal dysgenesis, breast development, Graves' disease, and low bone mass.

Objective: To describe a case of XY gonadal dysgenesis with Tanner stage 4 breast development in the absence of a hormone-producing gonadal neoplasm and with Graves' disease and low bone mass.

Methods: The clinical features, laboratory results, and cytogenetic findings in the patient are presented, and the potential mechanisms of breast development are discussed. A MEDLINE search was performed, and related articles in the English-language literature published between 1955 and 2001 were reviewed.
