Testicular self-examination-
Men between the ages of 15 and 55 are advised by some doctors to examine themselves each month to look for any changes. After a warm shower, monthly testicular self-examinations can help discover cancer early, when it is more likely to be effectively treated.
When should the TSE do?
- Testicular self- examinations should start at age 15 and last until age 55. The exam must be completed monthly to detect any changes.
- The moment following a hot shower or a bath is the ideal time to check your testicles. At this stage, the testicles are easier to feel and the perineal skin is at its most loose. The examination only takes a few minutes and should be performed standing up.

The acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.
What is an acrosome?
An acrosome is a unique membranous organelle that is located over the anterior part of the sperm nucleus. It is highly conserved throughout evolution.
This acrosome contains a number of hydrolytic enzymes that help the sperm penetrate the egg's coats, when secreted.
The proteolytic enzymes such as hyaluronidase and acrosin are what help the sperm penetrate the eggs coat.
Acrosome comes from the Golgi complex of the spermatid. It consists of a protein matrix core and numerous hydrolytic and glycolytic enzymes, which are necessary for fertilization.
Therefore, the acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.

Answer:
Botulinum Toxin
Explanation:
Botulinum Toxin is a neurotoxin (meaning that its target is the nervous system) produced by a bacteria known as Clostridium Botulinum. The Botulinum Toxin inhibits the transmission of acetylcholine (principal neurotransmitter that participates in muscle contraction). The acetylcholine travels from presynaptic motor neurons (the neurons that control the movement) to the muscle at the neuromuscular junction (the place where the nerve gets in contact with the muscle) interfering with neural transmission and inhibiting the stimulation of the muscle fiber, thus causing muscle paralysis.
