Scientists created a test-tube model to simulate the effects of overheating (hyperthermia) on the seminiferous tubules-the tubes through which sperm pass on their way to seek out the ovum. One of the first suggestions for male infertility is that the man should wear boxers instead of briefs to allow the testicles to remain farther from the body, which in turn keeps them cooler. Too much heat hinders sperm production, but sometimes all that is required is to cool things off a bit, and fertility returns.
In their model of hyperthermia, these scientists found that overheating increased oxidative stress in the tubules. They theorized that this increased free-radical production was the culprit in decreasing sperm production. Goji acted as an antioxidant, which helped to reverse the effects of overheating on sperm production that can lead to infertility.
The Chinese call Goji the Matrimony Vine. It has been shown to increase the sperm count and the vitality of the sperm. It also has been used as an infertility herb and documented instances of conception with Goji as part of the diet for women with premature ovarian failure.
Research shows that Goji offers another option for treating female infertility in patients with Premature Ovarian Failure (POF).
Studies have shown an increased sperm count and sperm vitality after consuming goji berries. This possibly could help male infertility by strengthening the sperm and the count.
There are reports from Goji users of increased libido after drinking Goji Juice.
While the active ingredients and the mechanism of action underlying Lycium’s fertility-facilitating effects remain unknown, studies indicate the potential mechanism of action for this protective effect, and provide a scientific basis for the traditional use of this plant.
Comments: I also have a male friend that uses goji berries to help him “go for longer”. (It was hard to type that without giggling.) This study makes sense. Goji Juice contains a lot of antioxidants which help to decrease free radicals. Free radicals break down cells integrity, in this case the sperms integrity which causes damaged sperm and makes getting pregnant harder.
