Pituitary and serum luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels in adult FSHβ heterozygote control (11), FSHβ knockout (KO) (10), FSH receptor (FSHR) heterozygote control (7), FSHRKO (13), LH receptor (LuR) heterozygote/normal control (25), LuRKO (10), hypogonadal (hpg) heterozygote/normal control (18), hpg (13) and ovariectomised female mice (9). 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. Open columns, control mice; filled columns, mutant mice, knockout (KO) or hpg; striped columns, ovariectomised (OVX) mice. NS, not significant.
