R-HETE is a very potent and selective inducer of oocyte maturation [196, 199]. 8S-HETE does not show this activity. The allene oxide hydrolysis products and the hydroperoxide lyase products were not active in promoting oocyte maturation [200]. 

Progesterone produces direct membrane effects [16]. These include actions that promote maturation of spermatozoa as well as oocytes and facilitation of the release of neurotransmitters such as dopamine and LH-releasing hormone (LHRH) (Fig. 52-7). Membrane actions of progesterone also activate oxytocin receptors in the hypothalamus in a way that enables oxytocin to turn on sexual behavior in the estrogen-primed female rat [3],...
