Document Summary

Male: o can reduce the number of sperm by 13 17% o can cause dna damage to developing sperm cells o dna damage transmitted to embryos o. Female: o 3 4 times more likely to take > 1 year to conceive ( infertile groups) o compounds identified in follicular fluid and cells surrounding oocytes o causes dna damage to oocytes o ages ovaries by 10 years. Occupations at risk: o transport workers (heat & exhaust fumes) o building industry (pesticides, organic solvents, metals) o motor mechanics (hydrocarbons, estrogen) o farmers (estrogen, pesticides, herbicides) o miners (heat, metals, dust, estrogens) o carpenters (heavy metals) Semen analysis o volume o concentration o motility o morphology o ph, viscosity and appearance. Motility: o rapid linear (type a) o slow progressive (type b) o non progressive (type c) o. Cervical mucus score based on: o volume o consistency o ferning o thread stretching o cellularity o ph o number of sperm per field.
