Spermatogenic Cells Do Not Require Estrogen Receptor-α for Development or Function

Abstract excerpt

Estrogen receptors alpha (ERalpha) and beta (ERbeta) are ligand-dependent transcription factors and members of the nuclear hormone receptor superfamily encoded by separate genes. Male mice homozygous for a mutation in the gene encoding ERalpha are infertile. To determine whether germ cells or somatic cells require ERalpha, germ cells were transplanted from donor males homozygous for the mutation (ERalpha-/-) to...
