Pituitary and serum luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels in adult (8 week) FSHβH (5), FSHβKO (5), FSHRH (5), FSHRKO (4), LuRH/N (21), LuRKO (7), hpgH/N (15), hpg (9), tfm (5) and gonadectomised males (14) (normals from hpg colony, 4 weeks post gonadectomy). The number of mice in each group is shown in brackets. Results are expressed as the mean ± SEM. **P < 0.01 versus respective strain control; ++P < 0.01 versus comparison indicated by lines. Open columns, heterozygote/ normal control; filled columns, knockout/mutant; striped columns, gonadectomised (gdX) mice. KO, knockout; hpg, hypogonadal; tfm, testicular feminised.
