Paperback, 134 pages with bibliography
The theory of sperm causing diseases presented in this book takes on momentum with cannibalism and organ transplants found as causing diseases. Sperm ingested orally or injected into a rectum is cannibalism; and their invasions of membranes and tissues of genitalia and urethras are equivalent to transplants. The essence is the entrance into one’s body of cells of another individual. Sperm invade the delicate linings of the internal and external genitalia of both men and women, enter blood streams, and go to all parts of their bodies.
Kuru, Creutzfeldt-Jakob disease (CJD), and Gertsmann-Stussler-Scheinker syndrome in humans, scrapie in sheep and goats, and bovine spongiform encephalopathy in cows are diseases with some clinical aspects in common including neurodegeneration. Anthropologist Robert Glasse connected kuru to gastronomic cannibalism by women and children [in New Guinea], avoided by adult males due to the belief that cannibalism ‘robbed a man of his vitality.’ Incubation periods are notably long, with 30 years common in kuru and CJD.
In this book sperm of the other guy are postulated as the cause of many diseases all over the body including cancers. Experimental, clinical, and epidemiological evidence in support is presented.
Precursors of sperm have a tremendous stimulus to divide producing 100,000,000 to 300,000,000 sperm per ejaculate. The union of a sperm with an ovum produces rapidly dividing cells that can result in a 6 to 10 pound baby in 9 months. The unidentified factor that causes cells to divide decreases in amount or activity in each division of offspring cells until there is no weight gain at maturity when cells die at the same rate they divide. Sperm invading cells other than ova accounts for rapid uncontrolled dividing of cancer cells. DNA of sperm is undifferentiated, capable of producing any type of cell. Sperm, invading cells other than ova accounts for all characteristics of malignant cells including their uncontrolled dividing, invading, having abnormal numbers of chromosomes, and being undifferentiated.
Reaction of a host body to invading sperm can be similar to its reaction to bacteria and viruses. In most instances there is no disease at the site of sperm entry. Entry-site diseases include mucoid and purulent discharges diagnosed as gonorrhea and nonspecific urethritis and sores diagnosed as herpes, chancroid, or syphilis.
Sperm and their parts invading a body are the equivalent of transplants of any and all cells or organs. Antibodies attacking the genes of the sperm, probably at times attack corresponding cells and organs of the host. That is a probable cause of ‘autoimmune’ diseases including most arthritis, diabetes, thryroiditis, and lupus erythematosus.
Roles of sperm in AIDS, urinary infections, congenital and inherited defects, atherosclerosis, and bestiality are presented.
Cancer cells are often aneuploid but that doesn’t meant that the scientists have detected exogenous human DNA in them.
If this theory were true, straight men would have low cancer rates compared to their wives. And spinsters, nuns and celibate eunuchs would be safe.
