Fertilisation cannot occur until the egg is released on ovulation day, but the sperm can wait for the egg. Is a 10 percent decrease in "progressive motile" sperm really going to make a difference? However, sperm can live inside the body for five days as long as the conditions are favorable. CDC recommends that people get MMR vaccine to protect against measles, mumps, and rubella.
