Cancer in the male organs that make male hormones and sperm (testicles).The testicles are located inside a loose bag of skin (scrotum) underneath the penis. Symptoms include a lump in either testicle or a feeling of heaviness in the scrotum. Most often, the first symptom of testicular cancer is a lump on the testicle, or the testicle becomes swollen or larger. Some testicular tumours might cause pain, but most of the time they don't. Men with testicular cancer can also have a feeling of heaviness or aching in the lower belly (abdomen) or scrotum.

This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. The inclusion of these publications provides the opportunity for editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly. Impact factor plays a major role for the particular journal. Journal with higher impact factor is considered to be more important than other ones.
