In this study they examined the effects of cows milk on mouse testicles. They found that Cows milk lowered serum testosterone levels and reduced the weight of the seminal vessicles. In general, dairy is not a great idea for male fertility in my opinion. For female fertility there is some support for using dairy, however, there is a lot of contamination in dairy products so unless you are getting pristine dairy, its best to avoid.

In this first study, researchers orally administered black pepper to male mice. They found that 0.5mg (the equivalent of 1 - 2 grams of black pepper per day in humans) was enough to induce testicular damage and resulted in a reduced litter size. The second study, researchers administered raw garlic and found that the rat germ cells (meaning the things that become sperm) would die off. This goes along with what we’ve been teaching for many years: many of the foods that are good at killing cancer cells, are good at killing your fertility as well…

With serious lapses of hygiene in hospitals, we are now facing an epidemic of antibiotic resistant strains of potentially deadly microorganisms that are now being found outside of hospitals. One of these antibiotic resistant organisms is known as MRSA (methicillin-resistant Staphylococcus aureus). MRSA initially looks fairly innocent and may resemble pimples, boils or spider bites. However, they can then turn into abscesses and go into the body, causing potentially life-threatening infections. This is one of the reasons we are always wearing gloves in our clinic. MRSA is spread between patients very easily by doctors, nurses, etc. It is especially common on cell phones, ties, stethoscopes, pagers, etc. So if your doctor washes her hands and then checks her pager and touches you, that could spread MRSA or other organisms.
 
So it’s not a surprise that researchers are frantically looking for compounds that these bacteria are not resistant to and so they are turning to phytochemicals (plant-chemicals) for clues. In this study, they looked at Olive leaf extract and found that it was able to kill MRSA. Interesting it was also selective against Campylobacter jejuni, Helicobacter pylori.

A new study found that distal metastases for breast cancer tumors occurs through the action of a molecule called Transforming Growth Factor beta or TGFb. It turns out that when TGFb is expressed, single cells break off of the tumor and can metastasize through the blood stream. However, without TGFb, only chunks of cells can come off the tumor which are too big to get into the blood stream. Thus they travel through the lymphtaics which are much slower and tend to stay local. This is very interesting news and they are now looking into drugs to downregulate TGFb. However, we don’t need to wait to take advantage of this fascinating research because acupuncture and certain herbs like astragalus have already been shown to downregulate TGFb. Steve Gomberg and Brandon Horn published an article in a peer reviewed journal called Alternative Therapies in Women’s Health discussing research on how powerful Chinese herbal medicine can be in fighting breast cancers. With the new information from this study, we now have yet another mechanism by which acupuncture and Chinese herbs can help: in this case, in the prevention of distal metastases.

In this study researchers looked at 4 groups of women with polycystic ovary syndrome (PCOS): (1) treatment with clomid, (2) treatment with metformin, (3) clomid + metformin (4) lifestyle modification. The results were that the lifestyle modification group achieved the highest clinical pregnancy rates (20%). The next best was clomid + metformin (14.8%). Our patients always ask us why we are so concerned with diet and exercise modifications and this is why. We see huge differences clinically in people who follow our dietary and lifestyle recommendations. This is the foundation of a successful treatment and the foundation of a healthy pregnancy. As you have seen from other posts, you can’t just do any kind of diet or exercise. This is why we have specific dietary recommendations for people with different conditions. If someone has poor ovarian function they generally don’t get the same diet as someone who has a lining problem unless they have the same underlying causes. Exercise is also crucial and can even make up for some dietary lapses. However, exercise can enhance or inhibit fertility depending on how you do it. The fertility yoga DVDs are excellent routines geared toward each part of your menstrual cycle. They provide the right kind of exercise at the right times of the month. You can learn more about them here.

This is yet another study demonstrating that the wrong kind of exercise can cause fertility problems. Researchers did a population based health survey in Norway examining close to 4,000 women and found that after adjusting for age, parity, smoking, and marital status, women who exercised on most days were over 3 times more likely to have fertility problems than inactive women. Out of the group that exercised a lot, if the exercise was to exhaustion they had double the odds of infertility when compared to those that had lower intensity workouts. The authors concluded that awareness of the possible risks of infertility should be highlighted among women who exercise vigorously. Interestingly, BMI (body-mass index) was not associated with fertility problems in this study.
 
Our clinical experience confirms this. Many of our fertility patients exercise regularly and vigorously and that was creating problems for them. However, proper exercise can greatly enhance fertility as it facilitates blood flow, proper hormone function, reduces stress and can balance the acid/alkaline ratios. So we created a yoga DVD that is specific to improving reproductive function. If you are interested, you can learn more about it here.

While not a new study, I just came across it. It turns out that men who had 100 orgasms per year had significantly lower mortality (50% lower!). This was especially the case for coronary heart disease. There is a caveat here though. The study only looked at men aged 45-59. So this turns out to be about 2 orgasms per week. In Chinese medicine they historically recommend less frequent orgasms as we age, so I would like to see what happens after 59 if they keep that up. My guess is that in the 60’s and 70’s it might be better to reduce orgasm to once per week and in the 80’s once every other week. In the 90’s you should probably have orgasms daily as a reward for making it that far.

In a frantic race to find substances to combat the most recent H1N1 outbreak, scientists have been looking to botanicals. In this study they found that Echinacea pupurea not only inhibited H1N1 by preventing its ability to enter cells (in vitro), but inactivated the virus as well. In addition, Echinacea inhibited the highly pathogenic avian influenza virus (H5N1, H7N7). The clincher is that it even worked against Tamiflu resistant strains! Also, Echinacea didn’t seem to develop resistant strains of H1N1. One caveat is that it worked best if it was taken prior to contact with the virus. Therefore it should be taken as a preventative and may not work as well after the fact.

A very interesting study that examined the effects of phthalate exposure during pregnancy on behavioral characteristics of boys found that they were much less aggressive due to the anti-androgen effects of some phthalates (i.e., they block testosterone). We’ve been warning our patients for years to minimize the use of plastics, however now I’m rethinking that. Perhaps what the world needs is to take a chill pill and become less violent. If plastics are the answer, then I guess we’ll just have to put up with smaller penises and lower testicular weights.

A Chinese herbal formula known as wu ling san was shown to not only reduce blood sugar levels, but to reverse the resulting kidney damage in mice. This is incredibly important if you are diabetic because the kidneys are one of the areas that can lead to serious diabetic complications such as dialysis. The fact that you may be able to not just prevent kidney damage, but reverse it is highly significant. If you or anyone in your family is diabetic, you should consider consulting with a professional. We don’t recommend self-prescribing. Herbs are just like pharmaceuticals (in fact many pharmaceuticals actually come form herbs) and you need to know when something is appropriate and, just as important, at what dose. You also need to know how to balance some of the herbs. In this case, the formula can cause a number of side effects if it is not appropriate for your particular constitution. A competent herbalist will know how to monitor you on the formula and how to identify and counteract side effects before they become problematic.
