The objective of this research work was to determine the influence of physical and chemical factors in the discovery of human spermatozoa in two types of support. The method was descriptive, quantitative with an experimental design. The sample consisted of complete or incomplete sperm, visualized in an optical microscope field at a magnification of 1000x. Garments impregnated with semen samples from 10 donors were used and were subsequently subjected to chemical factors, such as detergent and bleach, and to physical factors, such as humidity and temperatures of 4°, 14° and 24°C, at times of 0, 12, 24, 36 and 48 hours. The results show that in those garments subjected to washing with water and detergent, cotton and synthetic garments for up to 48 hours, they found different amounts of sperm between the control and sample groups. It is concluded that, in garments washed with water and bleach, in synthetic garments and in cotton garments, spermatozoa are no longer observed after 36 hours. In the same way, it was verified that the humidity in the garments, both cotton and synthetic, present spermatozoa for up to 48 hours and that, at a temperature of 14 degrees, cotton and synthetic garments remain stable in the amount of spermatozoa until 48 hours.
