When the man ejaculates his semen into the woman's vagina during intercourse, somewhere in the range of 60 to 450 million microscopic sperm cells are dispatched. The sperm liquid contains various sugars that serve as nutrition to help the sperm cells stay alive and reproductive for about 2-3 days.
Anatomically speaking, a sperm cell consists of a head, a mid-piece, and a long, thin (moveable) tail section. The head contains the nucleus with the genetic coding. Inside the mid-piece are the mitochondria, the small "powerhouses" that make the energy required for forward motion and tail-wagging action.
Of all human cells, sperm cells are among those with the highest energy requirement. They need the energy to swim the relatively long distance from the vagina to the uterus and fallopian tube where the actual conception takes place. It is really like a huge race where only very few sperm cells are able to complete the 15-25 cm distance to the large egg.
The more healthy sperm cells a man is able to produce, and the faster they are able to swim, the greater the chances that one of these sperm cells will reach its goal and fertilize the egg.
This is where B-Daddy can contribute to the whole process by ensuring healthy, well-functioning sperm cells.
N.B.: Good sperm quality also requires relatively low temperatures and generous space in and around the genital area. Wearing trousers that are too thick or tight may cause the temperature to rise and the sperm quality to drop correspondingly.
Fertility is determined by, among other things, the amount of viable sperm cells. However, other factors play a role. For instance, a sperm cell's motility (ability to swim) may be affected by DNA-damage that causes abnormally shaped sperm cells. Also, lack of energy can limit the forward progression of the individual sperm cell.
