Immature female rats (75 g body wt, aged 29 days) were injected with 4 or 40 i.u. PMSG on Day -2 and were killed at intervals between 18:00 h on Day -2 and 09:00 h on Day 1. Control animals (4 i.u.) ovulated between 00:30 and 05:30 h on Day 1 whereas the number of ova recovered from superovulated rats (40 i.u. PMSG) increased slowly between 06:00 h on Day -1 and 24:00 h on Day 0 and markedly between 24:00 on Day 0 and 06:00 on Day 1. Similarly treated rats were caged overnight on Day 0 with… CONTINUE READING
