Two forms of GnRH (GnRH I and GnRH II) are expressed in the brain of human and some primates. Even though primates have been used extensively in a variety of investigations in relation to the role of GnRH in reproduction, there is no evidence of any research to investigate the direct effect of GnRH on primate sperm.enGametogenesisSpermatozoaMotilityMonkeys as laboratory animalsThesisUniversity of the Western Cape
