The spermicidal powers of the various chemical contraceptives sold to the public have never previously been compared, and no one has been in a position to say that one spermicide is preferable to another. The only literature on the subject consists of the pamphlets issued by the makers of the different pessaries, and these give little or no information on the length of time taken to kill sperms at stated concentrations. The Birth Control Investigation Committee therefore asked me to undertake…

The Spermicidal Powers of Chemical Contraceptives: II. Pure Substances

1. A technique for comparing the spermicidal powers of pure substances is described in detail. It is hoped that this may be accepted as the standard technique for the purpose. 2. The killing

The Spermicidal Powers of Chemical Contraceptives: III. Pessaries

TLDR
Semori is the most spermicidal pessary of the nine investigated, and Speton relies for its sPermicidal power wholly upon its foam-producing substances.

A CRITICAL STUDY OF METHODS OF MEASURING SPERMICIDAL ACTION

TLDR
In this laboratory the effect of pure spermicides are tested by the Sander-Cramer test while the finished preparations are examined not only by that test and the Brown-Gamble but also by saturation and zone tests.

TLDR
In Britain contraceptive standards were imagined and implemented at least two decades earlier by the Family Planning Association, which sought to legitimize contraceptive methods, practice and provision through the foundation of the field of contraceptive science.

Studies on spermicidal activity of surfactants. I. Correlation between spermicidal effect and physicochemical properties of p-menthanylphenyl polyoxyethylene (8.8) ether and related surfactants.

TLDR
The close relationship between spermical activity and partition coefficient suggests that the spermicidal activities of these surfactants are associated with their structural affinity to the lipids of spermatozoal cell membrane.

TLDR
Striving to change the status of contraceptives and to promote safe and efficient products that reduced fertility in humans shaped some of the key features of the present-day production and regulation of pharmaceuticals.
