[An evaluation of sterility today]

Abstract:
After a reminder of the epidemiology: fertilization ability, fertility, hypofertility, the classic work-up of a sterile couple will be presented: temperature, hormonal evaluation, sperm count, cervical secretions, PCT, hysterogram. With each examination, a critical study of the evaluation of the results will be developed and possibly new ideas will be approached. Such a review reveals, most of the time, the etiology of the sterility. If this is not the case, after systematic laparoscopy, the rate of unexplained sterility will be approximately 5 p. cent. This small number of "unexplained sterilities" could then benefit from the most sophisticated new techniques, especially in-vitro fertilization of which the results, in terms of pregnancy, are identical in tubal pregnancies and unexplained pregnancies.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
Methods of Sterilization II: Chemical Methods
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
