Cellular and Molecular Basis of Human Biology

Essential for the propagation of next generation, this system’s sole function is to produce important reproductive elements and provide the nurturing environment for the reproduction of offspring. In the male reproductive system, it is primarily composed of sperm factory (testis), sperm delivery ducts (vas deferens and ejaculation duct), prostate gland (provides sperm nutrient), and penis (containing the sperm outlet, urethra). The counter part of female reproductive system is consisted mainly of ovary (egg factory), oviduct (egg transport duct) uterus (fetus’ home at pregnancy), vagina, and mammary gland (for baby feeding) (Reece et al. 2014). The reproductive system, like any other system in the human body, also required the collaboration of other systems to function properly. The cardiovascular system is needed to equip the sexual organs to proper function during sexual intercourse and it is also needed to develop a mother-to-child oxygen and nutrient transportation during pregnancy. The development and maturation of the reproductive organs require the endocrine system to provide the proper hormonal stimulation. The very desire of sexual act is also dependent on hormones from the endocrine system. Angiogenesis, the ability of generating new blood vessels, in the uterus, is absolutely essential for the implantation of the fertilized egg and the subsequent development of placenta that sustains the growth of the fetus and it is a function of the cardiovascular system (Reynolds et al. 1992).

Prostate cancer is a form of cancer that develops in the prostate gland of the male reproductive system. Most prostate cancers are slow growing; however, there are cases of aggressive prostate cancers. The cancer cells may metastasize (spread) from the prostate to other parts of the body, particularly the bones and lymph nodes. Prostate cancer may cause pain, difficulty in urinating, problems during sexual intercourse or erectile dysfunction. Other symptoms can potentially develop during later stages of the disease.
The Amazing Architecture of the Human Immune System
Published in Rocky Dr. Termanini, The Nano Age of Digital Immunity Infrastructure Fundamentals and Applications, 2018
The reproductive system allows humans to reproduce. It is key to the production and survival of the human race. The male reproductive system includes the penis and the testes, which produce sperm. The female reproductive system consists of the vagina, the uterus, and the ovaries, which produce eggs. During conception, a sperm cell fuses with an egg cell, which creates a fertilized egg that implants and grows in the uterus.

Male reproductive system is responsible for production, storage and transport of sperm under hormonal control. The sperm and testosterone hormone are produced in two testes protected in the scrotal sac. The sperm pass from the testis to the epididymis where the storage of sperm occurs. Just before ejaculation, the sperm pass from the epididymis to the vas deferens. The vas deferens joins the ejaculatory duct from the seminal vesicle. At time of ejaculation, the sperm mix with the seminal fluid produced by seminal vesicle and prostate to produce semen which passes out of the body through urethral meatus [14].
