Male reproductive system

Male reproductive system:

  Unlike the female reproductive system, most of the male reproductive system is located outside of the body.

Structures of the Male Reproductive System

     Male reproductive system consist of two main parts,

1. penis
2. Testis

 Penis:

        penis is an organ which is use for copulation.

 Testis:

    The testis (plural: testes) is responsible for the production of sperm and testosterone (male sex hormone)

Second and main organ of reproduction is testis.they are not involve in copulation.

  Other structures:

   Epididymis
       Site where sperm matures and develops the ability to be motile (i.e. ‘swim’) – mature sperm is stored here until ejaculation
Vas Deferens
       Long tube which conducts sperm from the testes to the prostate gland (which connects to the urethra) during ejaculation
Seminal Vesicle
     Secretes fluid containing fructose (to nourish sperm), mucus (to protect sperm) and prostaglandin (triggers uterine contractions)
Prostate Gland

      Secretes an alkaline fluid to neutralise vaginal acids (necessary to maintain sperm viability)
Urethra
       Conducts sperm / semen from the prostate gland to the outside of the body via the penis (also used to convey urine)

The purpose of the organs of the male reproductive system is to perform the following functions:

• To produce, maintain, and transport sperm (the male reproductive cells) and protective fluid (semen)
• To discharge sperm within the female reproductive tract during sex
• To produce and secrete male sex hormones responsible for maintaining the male reproductive system

The entire male reproductive system is dependent on hormones, which are chemicals that regulate the activity of many different types of cells or organs. The primary hormones involved in the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.
Follicle-stimulating hormone is necessary for sperm production (spermatogenesis), and luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm. Testosterone is responsible for the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and sex drive.
