April 11 Study Guide

are divided into lobules and each lobe contains seminiferous lobules (little coiled tubules).

is produced by the interstitial cells of leydig

Essential organs of reproduction are referred to as _____________; testes for male and ovaries for women

is the male gametes with 23 chromosomes

are soft and close once calcified

is stimulated by testosterone

would be from wearing jeans too tight

is a swollen prostate

has 2 ducts that pass thru the prostate gland and they deliver sperm to the urethra

is going to delivers sperm to the Vas deferens

comes from synthetic estrogen in the foods (primarily dairy, cattle, chicken, egg)

is needed when a man gets BPH and they have to urinate but can’t get it out.

come from stress to the adrenal glands.

When sperm count gets below 25 million per mL, it is considered

deliver sperm to the epididymis which is a tightly coiled tube 20 feet long

Prostate also contains

It is a continuation of the exocrine delivery of the sperm

This causes muscles to grow and maintain. It promo
maleness (vocal cords), hair distribution, and male sexual behavior

At puberty there is a secretion of a molecule called

produce the hormone inhibin which reacts with FSH (follicle stimulating hormone) production

They produce sex cells that are called gametes

Testes are divided into lobules and each lobe contains seminiferous lobules (little coiled tubules). Inside those tubes are

The ______________ produce sperm (because it is in a tube it is exocrine)

is secreted by the anterior pituitary if the sperm production is too low

These are significant because they only have half the chromosomes

At the beginning of the penis you have the

is where vasectomies are performed

Seminal vesicles join the vas deferens just prior to the

Prostate problems are caused by the prostate forming a _______________ that is looking
for zinc

They pass thru the inguinal canal as part of the spermatic cord. It is part of the spermatic cord which contains arteries and veins

Along the way it helps the development of the sperm and also secretes a small amount of the seminal fluid meaning semen.

secrete an alkaline semi viscous liquid which represents 60% of the semen. The significance of alkaline is the semen has to help neutralize the acid pH of the vagina

competes with the prostate for zinc

Outside the seminiferous tubule there are

They have gone through meiosis or meiotic division

Testosterone is referred to as an ___________ so this protein will bind with the testosterone

When it starts being produced at puberty, it starts closing the epiphysis or the epiphyseal plates (growth plates

is what turns it into cancer

bulboureatheral glands that secrete an

secretes a watery substance slightly acidic (not enough to overcome the alkaline fluids that it is mixed with) provides about 30% of the seminal fluid

Sperm has been produced by the _______________ and matured along the way before
ejaculation

has a head and a midpiece and a tail

passes thru a small hole in the center of the prostate which can be problematic

This is found in soft drinks, plastics, and polluted air. It sticks where the storage spots for zinc are in the prostate causing swelling

contains citrate which is a nutrient for the sperm

It also contains fructose which is going to provide energy to the sperm following ejaculation

seminal fluid meaning

It binds to testosterone to increase the concentration to cause normal sperm production

when a male starts into puberty it starts the _____________of growth stages

takes 46 chromosomes and randomly selects some traits or genes which are passed on to the new life

in order to be effective sperm have to undergo a process called

sperm head has a cap on it called a

are microscopic but fast moving at about 600 mph

The midpiece or the body of the sperm contains the _____________ which will provide the energy
for the sperm

acrosome (ramming plate) contain __________, which are there to break down the cervical mucus allowing the sperm to pass into the uterus

____________ of sperm are necessary for fertilization to take place

If an ovum or an egg is present in the uterine tubes, the _____________ will digest the outer covering of the egg so the sperm can penetrate the egg

may decrease the risk of disease or even penile cancer and it will decrease urinary tract infections

Temperature for optimal sperm formation is about ____ degrees Celsius below normal body temperature which is why the testes are on the outside of the body (air cooled)

are painful and sometimes have injuries that occur which could be infection from the procedure or urethral injury. It decreases sexual pleasure
