The rate of (Nitric Oxide) NO production
is critically dependent on the bioavailability of Arginine.
NO is a highly reactive, short-lived, lipophilic molecule
with a half life of a few seconds. L-Arginine Nitric Oxide
(NO) formulas are capable of producing
excessive NO
or
reduced endogenous NO production.
Reduced arginine availability results in reduced NO synthesis.
Arginine availability for NO synthesis is regulated by
de novo arginine synthesis, arginase activity,
and cellular arginine transport. Arginase is generated
by excessive NO levels, and is to be avoided under any
circumstance in an L-Arginine or NO formula.
Excess (excessive) NO creates a toxic environment
in the human body, and low levels of NO (reduced
endogenous NO) are ineffective, so NO highs and lows are
to be avoided. In terms of fertility in males, NO reduces
or inhibits sperm motility, while NOS inhibitors, which
inhibit the formation of NO, prevent the reduction of
sperm motility, indicating a role for the L-arginine-NO
pathway in the modulation of sperm motility and motility
survival.
Sperm motility is negatively affective by both reduced
and excessive endogenous Nitric Oxide (NO). The mechanism
of reduced fertility in males, related to NO,
is a function of the effect of reactive oxygen species
(ROS) on sperm membranes, which depresses sperm function.
Stress also exacerbates reduced motility of sperm. Excessive
NO levels in seminal plasma are associated with poor
sperm quality.
Excessive generation of NO can be toxic and reduce sperm
motility. Further, excessive NO contributes to the formation
of a highly toxic anion of peroxidation, called peroxynitrite.
The unpaired electrons of NO and O2 define peroxynitrite
as a 1-or-2-electron oxidant and nitrating agent, and
not a typical free radical.
Numerous clinical studies have demonstrated that peroxidation
decreases sperm count and motility, and loss of the capacity
of the spermatozoon to undergo the acrosome reaction and
fertilization.
Therefore, NO formulas and products must be produced
under strict GMP manufacturing guidelines utilizing long-term
proven methodologies in L-arginine biochemistry.
The manufacture of NO formulas and products should
not be attempted by persons unfamiliar with L-Arginine
NO toxic byproducts and the Blind Amino Acid
personality of amino acids, such as Arginine.
