Male Reproductive System

• The female has more external parts than the male.
• The male has more internal parts than the female.
• The male produces sperm cells, produces hormones, and secretes waste products (urine).
• Fertilization, or the union between the egg and the sperm, results in conception.
• Once the sperm cells enter the vaginal wall, it is very challenging for the sperm to reach the latter part of the egg.
• Out of hundreds and millions of sperm cells, two sperms cannot win.
• Sex cells, or gametes, include sperm cells and oocytes (female egg cells).
• It is possible for two sperms to win, resulting in fraternity twins.
• A zygote is developed after the union of an egg and a sperm, already fertilized.
• An embryo is developed after 2 months or more.
• A fetus is developed after 56 days onwards, when there is an organ developing, such as a heart.
• The scrotum is a part of the male reproductive system that protects the testis (testicles) and is the taga protect ng testis (testicles).
• A red structure in the scrotum is a muscle called the dartos muscle, which helps move the scrotal sack and testicles close to the body when it's cold and away from the body when it's hot.
• Sperm cells should be developed at a temperature less than our body temperature.
• The testis is the primary organ of the reproductive system that produces sperm and has tubes called seminiferous tubules where sperm production takes place.
• Interstitial cells in the testis are in charge of the production of male hormones, testosterone, and they secrete testosterone.
• The epididymis stores all sperm cells produced by the testis and is responsible for their continuous development and maturation.
• The ductus deferens (vas deferens) extends from the epididymis and is the pathway for sperm to reach the urethra.
• Male puberty is a sequence of events, stages of development, and if able to have the process of spermatogenesis, it starts around 12-14 years old.
• The corpus cavernosum consists of two erectile tissue (left & right), forming the bulb of the penis.
• Secreting organs of the male reproductive system include the glands of the penis, the prepuce, the corpus cavernosum, the corpus spongiosum, the seminal vesicle, the prostate gland, and the bulbourethral gland.
• Spermatogenesis is the formation of sperm cells, which happens during puberty.
• Balanitis is the inflammation of the penis.
• The prepuce, also known as the foreskin, is removed during circumcision.
• One million sperms can stay and live up to 72 hours in the female tract.
• The corpus spongiosum is the main tissue of the erectile tissue in the middle.
• The bulbourethral gland also neutralizes the acidity of the male urethra and female vagina.
• Normal sperm structure includes a tail (flagellum/flagella), midsection (midpiece), and head (contains nucleus and DNA).
• The seminal vesicle forms the ejaculatory duct, is full of fluids, and provides fructose.
• Normal semen volume is 2-5ml, and if it exceeds 5ml it is called HYPERSPERMIA.
• The major male hormone is testosterone, which is produced by interstitial cells.
• The prostate gland surrounds the urethra, liquefies the semen, and provides enzymes to the semen.
• Secondary sexual characteristics include cryphorchiidism (balls don't bumaba yung balls) and testicular torsion (twisting of testicles, no oxygen flow).
• The head of the penis is referred to as the glans penis.
• Prostaglandins help the sperm to travel to the cervix.
• The male reproductive system starts in the testicles with the seminiferous tubules, epididymis, vas deferens, seminal vesicles, prostate glands, bulbourethral gland, urethra, and ends with male secretion.
• The movement of a sperm depends on its morphology.
• The urethra is a passageway for both the sperm and urine, extending from the urinary bladder going to the opening of the penis.
• Females are more prone to UTI.
• The penis is an erectile tissue filled with blood because of sexual arousal which causes erection, and it also serves as an accessory gland which transfers the sperm to the vagina.
