The release of hyaluronidase from spermatozoa

SEMINAL HYALURONIDASE 413first four species there is a close correlation between hyaluronidase content and sperm density.In the case of dogs and fowls no such correlation could be found.2. The absence of hyaluronidase in a cryptorchid and in prepubertal rabbit testes is demonstrated.The conclusion is reached that seminal hyaluronidase originates in active seminiferous epithelium and is not secreted by the accessory glands.3. The bearing of these results on the role of hyaluronidase in fertilization and its implication in the possibility of treatment of infertility due to oligospermia is discussed.
