This study, performed at The Johns Hopkins medical institutions in Baltimore, was the first long-term research concerning the incidence and mechanism of formation of sperm granulomas in rats following vas ligation. Both prepubertal and adult male rats were used in the experiments. Observation of more than 100 vasectomized rats showed sperm granuloma formation invariably occurs after vasectomy. Experimental results tended to eliminate the possibilities that leakage of sperm at the operation or suture material was a predisposing factor in granuloma formation. 6 months following vasectomy the average weight of a granuloma was .3-.7 gm. A typical lesion at this time contained massive accumulations of intact spermatozoa; thus, it is thought that after vasectomy sperm are incompletely reabsorbed by the epididymis. At 6 months a typical granuloma contained 20-200 times the number of sperm in a single ejaculate of the rat. It was noted that size of the granulomas could eventually decrease with time. The typical life of an area of granulomatous inflammation began with an accumulation of large masses of sperm bordered by a rim of epithelioid histiocytes which was rimmed by a perivascular accumulation of round cells. The whole lesion was limited by a fibrous capsule. Then the lesion seemed to progress to a pyogenic granuloma, many polymorphonuclear neutrophils moving into the sperm mass. The central mass was destroyed, and histiocytic response with active phagocytosis of sperm was more pronounced. A classical granuloma resulted, a smaller lesion with large numbers of epithelioid histiocytes with Langhans' giant cells. The reabsorption of sperm in granuloma formation may trigger alterations in the animal's immunology. Sperm are known as strong autoantigens.
Aspiration pneumonia is typically caused by aspiration of bacteria from the oral cavity into the lungs, and does not result in the formation of granulomas. However, granulomas may form when food particles or other particulate substances like pill fragments are aspirated into the lungs. Patients typically aspirate food because they have esophageal, gastric or neurologic problems. Intake of drugs that depress neurologic function may also lead to aspiration. The resultant granulomas are typically found around the airways (bronchioles) and are often accompanied by foreign-body-type multinucleated giant cells, acute inflammation or organizing pneumonia. The finding of food particles in lung biopsies is diagnostic. 
There are many remedies specifically for chalazion in the homeopathic shelf. To know which one to use, a homeopath will have to look at your list of symptoms and other pertinent factors (. lifestyle, temperament, etc.) before a final cure can be prescribed. One advantage with alternative medicine is that side-effects like an upset stomach and other gastrointestinal pain usually associated with antibiotics, are relatively uncommon. Homeopathic remedies for chalazion are also recommended by its advocates and experts because they treat the inflammation at the source. More specifically, homeopathic remedies treat an individual’s propensity for styes and chalazia such that once the course of treatment is complete, chalazia are not expected to return.
