hello hope this answer finds you all health and happy further i do like to share that it is really very important for the sperm to be fresh for fertility. as having sex or by other way keeping your sperm fresh this helps in keeping sperms clear from the testicles and the natural built-up dna damage. dna damage lessened in the sperm of men who had daily sex: "old" sperm was cleared and replaced by fresh cells. thanks
does it make a difference how long it's been since last ejaculation? does sperm have to be kept fresh to be fertile?
