(Received 28 March 1978)

Ovulation can be induced precociously in the prepubertal female rat by the administration of pregnant mare serum gonadotrophin (PMSG), provided that the animal weighs over 60 g (Wilson, Endersby & McDonald, 1974). The hormonal changes brought about by this treatment have been studied (J. C. Buckingham, M. B. ter Haar, A. S. McNeilly & C. A. Wilson, data to be published) and it has been found that the preovulatory concentrations of radioimmunoassayable luteinizing hormone (LH) varied according to the antiserum used. These findings are described in the present communication.

Female Sprague–Dawley rats (Tuck & Sons, Rayleigh, Essex) were brought into the department on day 21 of life, kept under conditions of controlled lighting (lights on 05.00–19.00 h) and provided with pelleted rat diet (No. 86, Dixon &
