Abstract
A method of controlling male fertility in warm-blooded animals comprising vaginally administering to female warm-blooded animals an amount of a compound selected from the group consisting of a compound of the formula ##STR1## wherein R.sub.1 and R.sub.2 are individually selected from the group consisting of alkyl of 1 to 8 carbon atoms and benzyl or taken together with the nitrogen form a saturated 5 to 6 ring heterocycle optionally containing a second nitrogen or oxygen in the ring, R.sub.3 is .alpha.- or .beta.-methyl, n is an integer from 2 to 10; R.sub.4 and R.sub.5 together are =0 or R.sub.4 is selected from the group consisting of hydrogen, --OH and acyloxy of an organic carboxylic acid of up to 12 carbon atoms and R.sub.5 is selected from hydrogen, --OH, acyloxy of an organic acid of up to 12 carbon atoms and alkyl, alkenyl and, alkynyl of up to 8 carbon atoms, R.sub.6 and R.sub.7 together are =0 or are individually selected from the group consisting of hydrogen, --OH and acyloxy of an organic carboxylic acid of up to 12 carbon atoms or R.sub.5 and R.sub.6 form a double bond and R.sub.4 and R.sub.7 are hydrogen and their non-toxic, pharmaceutically acceptable acid addition salts in an amount sufficient to bind to the sigma receptor sites and inhibit the influx of calcium into the spermatozoid.
