The answer to your question is yes.

Regardless of a person's sex, many cells continue to reproduce throughout someone's entire adult life. Diploid cells, which are cells with two copies of each chromosome, are found throughout the body. The process of mitosis is the same for both males and females. During childhood, mitosis occurs more rapidly as the person grows larger. Yet, this does not completely stop during adulthood. Mitosis continues as new cells are reproduced in the body's tissues, skin, and digestive tract. This occurs because these cells are lost all the time and need replacing. Whenever you've experienced a cut on your skin, mitosis is occurring as part of the healing process.

In males, meiosis begins during puberty. This is different from females, who experience meiosis during fetal development. Meiosis results in the creation of haploid cells or gametes. These cells have just one set of chromosomes and are necessary for reproduction in any creature that reproduces sexually. In males, these cells are the sperm. Adult males are constantly producing new sperm. Therefore, meiosis usually occurs throughout the entirety of an adult male's life.
