Infertility And Uranium
No: Please forgive my frankness. The SLS claim is made up. The parabens claims have little biologic plausibility for breast cancer (the main focus) and have resisted demonstration. If you're reading a site claiming there's a terrible conspiracy and cover-up, you should be able to recognize disinformation. We live in a sea of carcinogens, mostly unavoidable; pepper, orange juice, and so forth. ...Read more
A couple of friends (both under 35, non-smokers, and in reasonably good health) have failed to conceive after 2 years of trying. A fertility clinic found no physical infertility issues. What are potential reasons for their failure to conceive?
Several: Basic tests evaluate the fallopian tubes, the uterus, the eggs and the sperm. Often an actual physical exam is not as helpful. Often subtle problems with the uterus are overlooked. If those basic tests are normal, then usually the problem is the actual fertilization of the egg and sperm. Sometimes the problem may be genetically abnormal eggs or embryos preventing implantation. ...Read moreSee 2 more doctor answers
Do the pesticides and other chemicals in food cause cancer? What about hormones and pesticides in meat?
Chemicals: If a chemical can kill a bug, it can kill you too. There are not alot of studies on modern pesticides and human cancers. You'll see them in 10-20 years, just like our ddt experience and the near extinction of the bald eagle. ...Read more
Can daily oral sex(swallowing discharge) benefit or harm partner?for male n female ?foods for inc. semen volume naturally and permanently???
No harm: There is usually no harm from daily oral sex. However, sexually transmitted diseases can be spread in this way as well, so that is the potential for harm. Human papillomavirus is frequently spread through oral sex, since it so prevalent. No foods I can think of to permanently increase semen volume. ...Read more
Are silica, talc and titanium dioxide cancerous? They are listed in California Proposition 65 as cancerous, but I see them in oral supplements a lot.
Depends on level: Prop 65 requires a warning on the product label if the level of chemical in the product poses a significant risk of cancer. If the chemical is listed as an ingredient, but there is no warning, this means that the quantity present is believed to be below that risk level. ...Read moreSee 1 more doctor answer
Can artificial trees made of PVC cause health problems includ. cancer to adults?Can these trees cause cancer b/c PVC releases dioxins, arsenic,&lead?
Be discerning: If you were to believe everything that you read about the supposed dangers of common chemicals, you would be reading uncritically. There is a lot of money in fear-mongering and no laws against people simply making stuff up. The plastic itself is inert though some of the chemicals used to make it have presented hazards to workers. As far as "releasing dioxins, arsenic and lead", news to me. ...Read more
Isn't 2% of sperm penetration for in vitro fertilization fine since there are millions of sperm and 1 egg?
Maybe: When we evaluate sperm , information can be used in certain ways, we can categorize sperm as normal, mildly abnormal or severely abnormal. We have some idea of how each parameter matters, but certain aspects are not understood . With significant abnormalities, sometimes the sperm just do not function as well, or sometimes the sperm may have genetic abnormalities and the effect goes beyond the #. ...Read more
Can extensive fasting have adverse effect on fertility and sperm count? What can be the causes and effects of regular ejaculation in child bearing?
No for short term...: From what i know, fasting would not impact fertility and sperm count until the extreme end-stage of malnutrition and dying. Ejaculation to shoot the sperm-containing semen into birth canal is the natural must to make women pregnant. But remember viable sperms move and travel to where is suitable for their survival to fertilize the egg. Of course, the women receiving semen get to be functional... ...Read more
Results of estrogen incudcing herbs in pubescent teen (g) if a teenage girl (12-17) in puberty takes herbs (fenu greek, soy, saw palmetto, ect) to increase breast size, are the chances of ovarian/breast cancer high for her? If she stops taking the herbs,
I have found some sort of build up in my scrotum, and an exponential loss in sexual desire. I'm 19, but not sexually active. No urine or sperm changes?
For 19 year old guys: this is markedly abnormal. It's something that you need to have a doctor help you with. It's usually a sign of an endocrine problem like inadequate amounts of testosterone when a young man loses interest in sex. Sometimes things are more complicated, like a different medical issue, a new awareness of sexual identity and sometimes depression, or even another hormone issue. Please see your doctor ASAP. ...Read moreSee 2 more doctor answers

I take a natures made multivitamin that contains soy lithium and soybean oil. Will this cause ED and infertility in men?
Unlikely: I know of no evidence for such a causal relationship. The amount of soy in a multivitamin is unlikely to cause either ED or infertility. Both the coreg (carvedilol) and the clonodine you are taking can lower BP, and clonodine has known side effects that affect sexual function. Talk with your doctor about side effects of your meds, and consider a consult with a health psychologist if symptoms persist. ...Read more
Unlikely. : You are correct in that soybean contain phytoestrogens, which have weak hormonal activity and theoretically can reduce fertillity. There is, however, no conclusive evidence that it does, and many cultures which consume large amounts of soy do not have appreciably different rates of paternity and infertillity. No randomized trials exist, however, and this is an area of intense study. ...Read more
