Male Infertility and Glutathione by Priya Shah

Why are Antioxidants Important for Sperm Quality?

Mammalian spermatozoa are coated by a membrane rich in polyunsaturated fatty acids. These fatty acids are extremely susceptible to oxidative damage by free radicals or Reactive Oxygen Species (ROS) by a process called lipid peroxidation (LPO).

Lipid peroxidation damages the sperm cell membrane. It is considered to be the key mechanism of ROS-induced sperm damage and leads to

> Loss of sperm motility

> Abnormal sperm morphology

> Reduced capacity for oocyte penetration

> Infertility

To protect sperm from damage, the body depends on powerful antioxidant enzymes in the body such as superoxide dismutase (SOD), catalase, and glutathione peroxidase/reductase (GPX/GRD).

Seminal plasma and spermatozoa have several antioxidant enzymes - glutathione peroxidase, glutathione reductase, superoxide dismutase.

Some amount of all the antioxidant enzymes, which may protect spermatozoa from oxidative attack, are also made by the epididymis during storage.

The glutathione peroxidase/reductase enzymes play a central role in the defense against oxidative damage in human sperm.

Why is Glutathione important for Sperm Quality and Fertility?

A decrease in levels of reduced glutathione (GSH) during sperm production is known to disrupt the membrane integrity of spermatozoa due to increased oxidative stress.

Intracellular glutathione levels of spermatozoa are known to be decreased in certain populations of infertile men. Compared with a control group, the infertile men in all groups had significantly higher levels of ROS and lower levels of total antioxidants.

There is strong clinical evidence to show that men diagnosed with infertility have high levels of oxidative stress that may impair the quality of their sperm.

In some groups, higher levels of ROS were associated with lower sperm counts and defective sperm structure, while lower antioxidant levels correlated with reduced sperm movement.

Previous evidence has also shown that oxidative stress can decrease a sperm's life span, its motility, and its ability to penetrate the oocyst, or egg cell.

Up to 40% of men with unexplained male infertility have higher levels of free radical activity in their bodies.

Because men with high levels of ROS have a seven-fold lower likelihood of inducing a pregnancy than men with lower levels, researchers recommend that treatment for infertile men should include strategies to reduce oxidative stress and improve sperm quality.

How can Glutathione help in the Treatment of Infertility?

Glutathione is not only vital to sperm antioxidant defenses, but selenium and glutathione are essential to the formation of "phospholipid hydroperoxide glutathione peroxidase" - an enzyme present in spermatids - which becomes a structural protein in the mid-piece of mature spermatozoa.

When either substance is deficient, it can lead to instability of the mid-piece of the spermatozoa, resulting in defective motility.

Free radical scavengers - such as glutathione - that restore the structure and function of poly-unsaturated fatty acids (PUFA) in the cell membrane, can be used to treat these cases.

In a double-blind cross-over study of twenty infertile men, treatment with glutathione led to a statistically significant improvement of the sperm quality.

The study concerned men in whom the sperm quality was poor due to unilateral varicocele or germ-free genital tract inflammation - two conditions in which ROS or other toxic compounds are indicated as causative factors.

Treatment with glutathione was also found to have a statistically significantly positive effect on sperm motility (in particular forward motility) and on sperm morphology.

The findings of these studies indicate that glutathione therapy could represent a possible therapeutical tool in cases where ROS or exposure to toxins is the probable cause of infertility.
