Determination of tonicity in the non pregnant human uterus in vivo

The method hysterometry has been designed for the study of the effect upon the uterine muscle of pharmacologically active agents. Hysterometry has earlier been used on the pregnant uterus and is now described for the non-pregnant situation. The capacity of the technique is exemplified with results achieved in a study of the effect of prostaglandin synthetase inhibitors and beta-receptor stimulating agents during dysmenorrhea.
