do men take vitamins? which ones are the best?

My hubby takes zinc because it is supposed to help produce healthy sperm!

"Zinc and Sperm

Zinc is an antioxidant mineral that is also important in protecting sperm against free radical attack. Semen is rich in zinc, with each ejaculate containing 5 mg ­ one third of the recommended daily nutrient intake. This would imply that it plays an important role in sperm health. Three additional functions of zinc have been discovered apart from its important antioxidant one:

1. The genetic material (DNA chromatin) in the sperm nucleus is tightly wound with special proteins to form an insoluble, stable complex. This condensed structure is important for successful fertilization. Zinc is important for this structure and protects it from breaking down.

2. The high concentration of zinc in semen damps down sperm activity, keeping them in a relatively quiescent state. This lowers their consumption of oxygen and conserves sperm energy. Once within the female reproductive tract, which contains very little zinc, zinc concentrations are rapidly diluted. This causes a sudden increase in sperm activity, speeding them up and acting like a mineral turbo charge.

3. During fertilization, a sperm exposes enzymes in a sac at the sperm head to drill a hole in the outer egg shell through which the sperm can pass. This is known as the acrosome reaction. In many cases of subfertility it seems that large numbers of sperm discharge their enzymes spontaneously before or just after ejaculation. By the time they reach the egg they are no longer capable of penetrating it. This early discharge of the acrosome reaction is linked with a zinc deficiency.

High concentrations of zinc in semen helps to damp down the acrosome reaction in a reversible way. Once zinc concentrations become diluted within the female tract, the acrosome reaction can again occur.

Another recent finding is that zinc deficiency changes the sequence in which seminal secretions are ejaculated. The secretions from the seminal vesicle, which are usually ejaculated last, are released along with the sperm instead.

There are several theories why this happens. Lack of zinc may cause swelling of the prostate gland, which will slow sperm travelling up from the testes. This swelling will also slow the release of prostatic secretions, which are usually the first fluids to be ejaculated.

It is possible that this alteration in the ejaculatory sequence is a survival response to low concentrations of sperm zinc. By mixing the sperm and the relatively zinc-rich seminal vesicle secretions as early as possible, the protective effects of zinc (stabilization of sperm DNA; delaying of acrosome reaction; conservation of energy) are maximized.

Most men do not obtain enough dietary zinc. Those that are highly sexually active may be losing more zinc per day in their semen (5 mg per ejaculation) than they can keep up with in their diet. Men ideally need a minimum of 15 mg zinc from their diet per day (see zinc). "
 
good luck!! i got my bfp the first month of using my cbfm and presseed!!
