In 1921 he carried out experiments on rabbits and he demonstrated a temporary hormonal contraception in a female by transplanting ovaries from a second, pregnant, animal. His father was the eminent botanist, Gottlieb Haberlandt, plant tissue culture theorist and visionary; his grandfather was the European 'soybean' pioneer and trailblazer Friedrich J.

His father was the eminent botanist, Gottlieb Haberlandt, plant tissue culture theorist and visionary; his grandfather was the European 'soybean' pioneer and trailblazer Friedrich J. Haberlandt. In 1930 he began clinical trials after successful production of a hormonal preparation, Infecundin\u00AE, by the G. Richter Company in Budapest, Hungary. He ended his 1931 book, Die hormonale Sterilisierung des weiblichen Organismus, with a visionary claim: 'Unquestionably, practical application of the temporary hormonal sterilization in women would markedly contribute to the ideal in human society already enunciated a generation earlier by Sigmund Freud (1898). Theoretically, one of the greatest triumphs of mankind would be the elevation of procreation into a voluntary and deliberate act.' He was hounded for his views on reproductive biology up to his death from either suicide, or heart attack."@en . . . "Ludwig Haberlandt (* 1. Februar 1885 in Graz; \u2020 22.
