The Poor Health of Men Prevents Conception

Healthy sperm levels in "modern" men are declining. It is increasingly males who are responsible for their partners' failure to conceive. Men today do little exercise, eat too much fat and carbohydrates, and drink too much alcohol. It is no wonder their sperm counts are low. No longer can women be blamed for being overweight. Being a little overweight does not prevent women from conceiving. Men need to lose their beer guts, pleasantly referred to as love handles. Tests on male mice showed that obesity decreased the probability of fertilizing female mice. The success of embryo implantation was also decreased, and babies born from these males showed delayed fetal development. Three quarters of Australian men are overweight. This is way above the world average of 48 per cent. Male mice fed fast food gave disastrous results in producing healthy offspring. Foods that improve sperm count are eggs, sweet potatoes, yogurt, berries, seeds and nuts. Furthermore, consuming ...

Higher Rates of Birth Defects With "Injected" ICSI Babies

For many years we have heard nothing but good things about test tube babies, how they are strong and grow faster, etc. Maybe the "authorities" are telling us what we want to hear, with women choosing to have children later in life. Older women having babies had their age taken into account when measuring birth defects. If they smoked this was also given a mathematical allowance. This could be distorting the true picture. There has been a change in the way the "art" of test tube babies is done. Today, an individual sperm is injected into an egg. In the normal fertilization process only the fastest, healthiest sperm is successful. Evaluation of babies shows that birth defects occur in "injected" babies at a rate of 10 per cent. This compares to 6 per cent for naturally conceived babies. Couples who choose the older form of freezing embryos had normal rates of healthy babies. The attempt to get more embryos by injecting sperm, ICSI, seem...
