Abstract

In view of several cases of request to me to make "vaccination against pregnancy" by spouses, I ask not to refuse to inform: 1) To make single or multiple introduction of a sperm, and if multiple, in what intervals? 2) Is the semen administered in its pure form or in a warm solvent, and what is its dosage? 8) What is the technique of obtaining inoculum? Physician Panin.
Answer. At present, I do not use sperm inoculation to prevent pregnancy, since a special vaccine has been developed by me (in cooperation with Dr. E.I. Zabolotskaya). This vaccine is a carbolized physiological solution of NaCl, in which hetero-spermatozoa are suspended, killed by acetone. One cc contains 300,000 spermatozoa. Vaccinations are given four times in increasing doses with a 7-day break. A new single vaccination is required after 4-5 months. The vaccine is not commercially available, as it is still being tested. Experimental data and isolated observations on women have given quite favorable results. I hope to put the vaccine on sale as soon as it has been tested.
