Third, the timing of semen collection Xinmunet Xiao Bian tells you that although natural conditions, the cock will occur many times a day mating activities, but the number of ejaculation really occur is very small, and semen volume and sperm density decreased with the number of ejaculation increased. Artificial insemination is performed 3-5 times a week, and the cock is recovered after 48 hours of rest.
