Reproductive system in an organism is for the purpose of sexual reproduction. It is a system of sex organs within its body which is also called as genital system. Not only the sex organs but also the various non-living substances within the body such as hormones, pheromones, body fluids, etc form an important accessory to the reproductive system that works together for the purpose of sexual reproduction. The sexes of differentiated species often have significant differences in their respective genital systems. These differences allow for combination of genetic material between the two individuals, which in turn favors possibilities of greater genetic fitness of the offspring. Humans have a high level of sexual differentiation among male and female reproductive systems. In addition to the differences in their sex organs numerous differences typically occur in their secondary sexual characters. The human reproductive system involves internal fertilization. The production of gametes for the purpose of fertilization takes place within the gonads through the process known as gametogenesis. Specifically, it is termed as spermatogenesis in males while oogenesis in females. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
