A kidney stone is a solid mass made up of tiny crystals. One or more stones can be in the kidney or ureter at the same time.

Factors that increase your risk of developing kidney stones include:

Family or personal history of kidney stones.

1. Being an adult.
2. Being a man
3. Dehydration
4. Certain diets
5. Being obese
6. Digestive diseases and surgery
7. Other medical conditions

The prostate is a gland. It helps make semen, the fluid that contains sperm. The prostate surrounds the tube that carries urine away from the bladder and out of the body. A young man's prostate is about the size of a walnut. It slowly grows larger with age. If it gets too large, it can cause problems. This is very common after age 50. The older men get, the more likely they are to have prostate trouble

A varicocele is a dilated (enlarged) group of veins in the scrotum. Just like some people have dilated or "varicose" veins in their legs,

some adolescents have dilated veins in their scrotum.

The dilated veins are filled with excess blood.

MALE INFERTILITY:

Male infertility is a broad and complex area. The following information is intended only as a very general introduction to the subject of male fertility and infertility. We strongly encourage you to find a specialist in your area to fully evaluate your particular situation. There are a variety of male infertility treatments to help a couple reach their goals.

Likelihood of Occurrence

A male factor is involved in 60% of cases of couples' infertility. Forty percent are primarily male and 20% are combined male and female. Thus, when a couple is having trouble conceiving, it makes sense not only to evaluate the woman but to evaluate the man as well.

 Sperm takes 3 months to produce and mature and there is often a 4 to 6 month delay between treatment of the man and resulting changes in the sperm. Since the evaluation of the woman may take several months, it is recommended that a comprehensive and accurate semen analysis be scheduled at the outset in order to evaluate the male partner. Treatment of the man can then occur at the same time as treatment of the woman and there will be no additional delay once the woman's treatment is completed.

Causes:

- Varicoceles.
- Ductal System Problems.
- Immunological Infertility.
- Difficulties with Erections 
   and Ejaculations.
- Testicular Failure.
- Cryptorchidism.
- Drugs.
- Hormonal Abnormalities.
- Infections.
- Genetic Abnormalities.
- Lifestyle Factors.
- Recreational Drugs.

Treatment of Infertility

Treatment More that 50% of men will have a treatable cause of male factor infertility. These factors include varicoceles (dilated veins in the scrotum), infections, hormonal abnormalities, abnormalities in the seminal fluid, ductal blockages, and difficulties with erections and ejaculation. When these conditions are treated, either through medication (hormones or antibiotics) or surgery (varicocelectomy, vasal reconstruction, repair of a blocked ejaculatory duct), a man will often see a significant improvement in his semen analysis.

Those men with poor semen analyses whose conditions are not treatable may still have the option of using advanced reproductive techniques to achieve a pregnancy. Even those men with no sperm in the ejaculate may be able to have some living sperm procured from them through other methods and achieve a pregnancy using advanced reproductive techniques. Those few men who produce absolutely no sperm at all will have this information so that they can explore other options
