Broman Theory
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Broman's theory is a 1930s medical hypothesis explaining relative sterility in clinically healthy couples who are childless in their current marriage but have children from previous unions. It attributes this condition to a lack of harmony between germ cells, termed 'germ hostility' or negative chemotaxis between spermatozoa and the egg cell.

BROMAN'S THEORY (Broman), a theory proposed to explain relative sterility, i.e., infertility, in clinically healthy spouses who have no children in their current marriage but had them in previous marital relations. Broman speaks of a lack of harmony between germ cells, of "germ hostility," and of negative chemotaxis between spermatozoa and the egg cell. As a result, spermatozoa cannot reach the egg cell in the presence of a vigorous fluid current from the uterus of the given woman.
