Biochemistry of the cervical and endometrial content for the study of spermatic migration in sterile women.

We have reviewed the action of various substances contained in the cervix and endometrium, which are normally present and which can stimulate spermatic migration. We consider that the investigation is fundamental in certain pathological cases, especially concerning the study of the cervical factor and of certain cases of sterility without apparent cause, since they can indicate the etiology of sterility. The application of certain pharmacological substances, both of hormonal and non hormonal nature, can reestablish this balance and, with the recovery of spermatic migration, determine the ascent of the male gamete and render its encounter with the female gamete possible.
