Peyronie's disease does not cause infertility. It is a curvature of the penis when it is erect. It is typically seen in men between ages 30 and 50. It tends to be self-limited, meaning, it will stop progressing by itself. It does not always need to be treated.

Peyronie’s disease or PD is a localized disorder of the penis which is distinguished by collagen composition changes of the tunica albuginea. This results in a fibrotic plaque containing excessive collagen. Men suffering from PD complain of penile plaque, painful erection, penile shortening, penile curvature, and erectile dysfunction or ED. Peyronie’s disease is typically found in men between ages 40 and 70 years. See similar questions...

Whether one believes it or not, the disease in question is caused as a result of a sore throat. It may be tonsillitis/pharyngitis, or both. However, not all cases of sore throat cause this serious disease of the kidneys. It only occurs when the sore throat takes place due to the invasion of a specific bacteria called group A beta-haemolytc streptococcus. See similar questions...

In Peyronie’s disease, penile curvature is caused by an inelastic scar or plaque that shortens the involved part of the tunica albuginea of the corpora cavernosa when erection happens. In about one third of patients, scarring involves the dorsal and ventral aspects of the shaft. The offsetting plaques may make the penis straight but shortened or may have a lateral bend.

While the majority of men have a very slight curve or sideways "hang" to the penis, about 400 men in every 100,000 suffer from the condition of severely bent or curved erect penis... See similar questions...

Survivors of testicular cancer: Fertility may be poor in the two years before testicular cancer is found. Although only 1 to 3 percent of men with testicular cancer get cancer in both testicles, the cancer-free testicle often is not totally normal. Men newly-diagnosed with Hodgkin’s disease, lymphoma or leukemia: The recent surgery, fever or physical stress these survivors can experience can often affect their semen quality.

Usually, the cancer treatment, not the actual cancer, damages a man’s fertility. Radiation and chemotherapy kill cells that are in the middle of dividing and growing, when they are easier to damage. Cancer cells divide much more often than most normal body tissues, so they are killed off while normal cells survive. However, hair and sperm cells also grow constantly, making them sensitive to chemotherapy or radiation. See similar questions...

In order to try to identify the cause of infertility, we routinely depend on an initial history and physical exam, a hysterosalpingogram (an x-ray of the pelvis), a semen analysis (sperm count), some basic blood tests, and at times, an ultrasound exam. At times, patients may need further evaluation with additional tests on an individual basis. Dr. Witten takes pride in guiding patients through their evaluation with efficiency, compassion, and understanding. See similar questions...

Infertility is a disorder of the reproductive system. It is not caused by stress, although being unable to conceive can be a major source of stress for infertile couples. Simply relaxing does not cure infertility or any other physical illness. Fertility problems can be very emotional and it is important to recognize that medical treatment and emotional support is readily available. See similar questions...

Smoking may be responsible for almost 75% of periodontal diseases among adults. Tobacco products damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. An example of the effect is receding gums. A receding gum line exposes the tooth roots and increases your risk of developing a sensitivity to hot and cold, or tooth decay in these unprotected areas.

Many women still conceive with a tilt in their uterus, so it does not cause infertility. The problem with a tilted uterus is that it can lessen the amount of blood flow, inhibit fluid nerve conduction/communication, and lead to uneven energy flow and lymphatic accumulation.

Antibodies that attach to the sperm may impair motility and make it harder for them to penetrate the cervical mucus and gain entrance to the egg; they may also cause the sperm to clump together, which is occasionally noted on a routine semen analysis. Antibodies may also interfere with the ability of the sperm to fertilize the egg. See similar questions...

Fibroids are not usually a cause of infertility. In order to cause infertility, the fibroids must be growing very close to and actually obstructing the uterine openings of the Fallopian tubes, and block the passage of the egg as it enters the uterus. Both tubes must be blocked, since only one open tube is needed for pregnancy to occur. See similar questions...

No. Basically pills cover up whatever your body would have done over the time you took them, but they don't alter what your natural history is. For example, if you take pills from age 20 to 35 and then stop, your chances of getting pregnant are the same as any 35 year old who just started trying. At 35 it may be slightly more difficult to get pregnant but the pills don't cause it; age or other intervening disease or circumstances does. See similar questions...

Painful periods do not affect fertility. In fact, for most patients, regular painful periods usually signal ovulatory cycles. However, progressively worsening pain during periods (especially when this is accompanied by pain during sex) may mean you have endometriosis. See similar questions...

The cause is thought to be a labour-inducing chemical called prostaglandin that is found in oral bacteria. Very high levels of prostaglandin are found in women with severe periodontal disease. Another recent study has also found a possible link between periodontal bacteria and pre-eclampsia*. The study found that 50% of placentas from women with pre-eclampsia were positive for one or more periodontal pathogens, compared to just 14.3% in the control group. See similar questions...

Can inflammatory bowel disease cause colon cancer? The short answer is yes. People who suffer from inflammatory bowel disease (IBD) are at increased risk for colon cancer because the tissue of the colon is inflamed for a long period of time. Women with a personal (or family) history of uterine cancer may have a greater risk of developing colon cancer. If the uterine cancer was caused by a particular genetic mutation, women are considered at high risk for colon cancer. See similar questions...

Influenza A viruses have 16 H subtypes and 9 N subtypes. Only H5 and H7 subtypes are known to cause the highly pathogenic form of the disease. Fortunately, not all viruses of the H5 and H7 subtypes are highly pathogenic and not all will cause severe disease in poultry. Normally, H5 and H7 viruses are introduced to poultry flocks in their low pathogenic form. When allowed to spread among domestic poultry, the viruses can mutate, usually within a few months, into the highly pathogenic form. See similar questions...
