we’ll talk about the relationship between Brachytherapy of prostate cancer treatment and sterility.

Brachytherapy radiation through a direct effect or through indirect effects of free radicals was generated to destroy the DNA double-strand,Instead of splitting the tumor cells can survive longer.

Generally cells in M phase and G2 phase of the radiation sensitive, the S phase cells are not sensitive Brachytherapy treatment and the permanent implantation, including short-term treatment of particle planting.The following is on the use of brachytherapy for prostate cancer which lead to sterility relevant knowledge. According to a small study the results and brachytherapy treatment of prostate cancer in men does not always occur in sterility.

Studies have shown that prostate brachytherapy can reduce semen volume and changes in semen viscosity.

Therefore, many researchers have speculated that these male sterility.

In one study, Massachusetts General Hospital Joseph A. Grocela doctor and his colleagues have described the male partner of prostate brachytherapy treatment occurred in three cases of unintended pregnancy.

2 cases of full-term pregnancy has produced two healthy babies. Another one cases of pregnancy, with the first 3 months of spontaneous abortion. Although the treatment of male semen is less, with a total sperm counts slightly reduced, But their sperm morphological characteristics is consistent with the provisions of most or all of the normal standards of the World Health Organization.

The researchers believe that these men received radiation doses of 0.03 Zhi 2.5 Gy, the sperm germinal center is expected to have little or no effect.
