A vasectomy is a simple operation designed to make a man sterile, or unable to father a child. It is used as a means of contraception in many parts of the world. A total of about 50 million men have had a vasectomy -- a number that corresponds to roughly 5% of all married couples of reproductive age. In comparison, about 15% of couples rely on female sterilization for birth control.
Approximately half a million vasectomies are performed in the United States each year. About one out of six men over age 35 has been vasectomized, the prevalence increasing along with education and income. Among married couples in this country, only female sterilization and oral contraception are relied upon more often for family planning.
Vasectomy involves blocking the tubes through which sperm pass into the semen. Sperm are produced in a man's testis and stored in an adjacent structure known as the epididymis. During sexual climax, the sperm move from the epididymis through a tube called the vas deferens and mix with other components of semen to form the ejaculate. All vasectomy techniques involve cutting or otherwise blocking both the left and right vas deferens, so the man's ejaculate will no longer contain sperm, and he will not be able to make a woman pregnant.
What are the different vasectomy techniques?
In the conventional approach, a physician makes one or two small incisions, or cuts, in the skin of the scrotum, which has been numbed with a local anesthetic. The vas is cut, and a small piece may be removed. Next, the doctor ties the cut ends and sews up the scrotal incision. The entire procedure is then repeated on the other side.
An improved method, devised by a Chinese surgeon, has been widely used in China since 1974. This so-called nonsurgical, or no-scalpel, vasectomy was introduced into the United States in 1988, and many doctors are now using the technique here.
In a no-scalpel vasectomy, the doctor feels for the vas under the skin of the scrotum and holds it in place with a small clamp. Then a special instrument is used to make a tiny puncture in the skin and stretch the opening so the vas can be cut and tied. This approach produces very little bleeding, and no stitches are needed to close the punctures, which heal quickly by themselves. The newer method also produces less pain and fewer complications than conventional vasectomy.
Regardless of how it is performed, vasectomy offers many advantages as a method of birth control. Like female sterilization, it is a highly effective one-time procedure that provides permanent contraception. A vasectomy is medically much simpler than female sterilization, has a lower incidence of complications, and is much less expensive.
Rheumatoid arthritis is an autoimmune disease that causes chronic inflammation of the joints, the tissue around the joints, as well as other organs in the body. Because it can affect multiple other organs of the body, rheumatoid arthritis is referred to as a systemic illness and is sometimes called rheumatoid disease.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Multiple sclerosis (MS) is a disease which progressively injures the nerves of the brain and spinal cord, reflected by alterations of virtually every sensory or motor function in the body. The cause of MS is primarily unknown. There are different types of MS including relapsing-remitting MS, primary-progressive MS, and secondary-progressive MS. Symptoms of MS rang from mild to severe and examples include visual disturbances, muscle weakness, spasm, and fatigue. Decreased concentration, memory loss, and impaired judgment. Treatment for MS is generally with medications.
Sexually transmitted diseases, or STDs,
are infections that are transmitted during any type of sexual exposure,
including intercourse (vaginal or anal), oral sex, and the sharing of sexual
devices, such as vibrators. Women can contract all of the STDs, but may have no symptoms, or have different symptoms than men do.
Prostate cancer is an uncontrolled (malignant) growth of cells in the prostate gland. Prostate cancer is the second
leading cause of death of males in the U.S. Prostate cancer is often initially
suspected because of an abnormal PSA blood test or a hard nodule (lump) felt on
the prostate gland during a routine rectal examination.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Blood in semen is also known as hematospermia. Blood in semen can be caused by many conditions affecting the tubes that distribute semen from the testicles (seminal vesicles) or the prostate gland. Symptoms that may accompany blood in semen include blood in the urine, fever, painful urination, pain with ejaculation, tenderness, and swelling in the testes or groin area. Urinalysis, ultrasound, and MRI may be used to diagnose blood in the semen. Treatment depends upon the underlying cause of blood in the semen.
Sexually transmitted diseases, or STDs, are infections that are transmitted during any
type of sexual exposure, including intercourse (vaginal or anal), oral sex, and
the sharing of sexual devices, such as vibrators. Although treatment exists for many STDs, others currently are
usually incurable, such as those caused by HIV, HPV, hepatitis B and C, and HHV-8.
Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.
Infertility is the diminished ability to conceive a child. The primary cause of infertility in men is a sperm disorder. In women, the primary cause of infertility is an ovulation disorder. Most forms of infertility can be treated. Conventional infertility therapies include drugs or surgery.
Male sexual dysfunction can be caused by physical or psychological problems. Common sexual problems in men include erectile dysfunction (impotence or ED), premature ejaculation and loss of libido. Treatment for sexual dysfunction in men may involve medication, hormone therapy, psychological therapy, and the use of mechanical aids.
Testicular cancer symptoms include a painless lump or swelling in a testicle, testicle or scrotum pain, a dull ache in the abdomen, back, or groin, and a feeling of heaviness in the scrotum. Treatment for cancer of the testicles depends on the type of cancer (seminoma or nonseminoma), the stage of the cancer, and the patient's age and health.

Pregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
There are a number of different methods of birth control to include: barrier methods, IUDs, hormonal methods, natural methods, and surgical sterilization. Birth control methods can be reversible or permanent. In simple terms, all methods of birth control are based on either preventing a man's sperm from reaching and entering a woman's egg (fertilization) or preventing the fertilized egg from implanting in the woman's uterus (her womb) and starting to grow.
Men's health is an important component to a happy lifestyle and healthy relationships. Eating healthy, exercise, managing stress, and knowing when to have medical tests for a particular age is key to disease prevention in men.
When you are pregnant, many sexually transmitted diseases (STDs) can be especially harmful to you and your baby. These STDs include herpes, HIV/AIDS, genital warts (HPV), hepatitis B, chlamydia, syphilis, gonorrhea, and trichomoniasis. Symptoms include bumps, sores, warts, swelling, itching, or redness in the genital region. Treatment of STDs while pregnant depends on how far along you are in the pregnancy and the progression of the infection.
There are four phases to the sexual response for men and women. Couple do not usually reach each phase at the same time, and they are dependant from individual to individual. The four phases of the sexual response cycle include phase 1, excitement; phase 2, plateau; phase 3 orgasm; and phase 4 resolution.
The presence of blood in the semen (ejaculate) is also called hematospermia. Hematospermia is an uncommon condition.
What are the causes of blood in the semen?
Blood in semen can be caused by many conditions affecting the male genitourinary system. Areas affected include the bladder, urethra, the testicles, the tubes that distribute semen from the testicles (known as the seminal vesicles), the epididymis (a segment of the spermatic ducts that serves to store, mature and transport sperm), and the prostate gland.
Blood in the semen is most commonly a result of a prostate-gland biopsy. More than 80% of men who undergo a prostate biopsy may have some blood in their semen that persists for
three to four weeks. Likewise, vasectomy can lead to bloody semen for about one week after the procedure.
In men with hematospermia who have not had a recent prostate biopsy or vasectomy, a number of beni...
