Well, honey, the muscle responsible for ejaculating sperm is called the bulbospongiosus muscle. It contracts during ejaculation to help propel the little swimmers on their journey. So, flex that muscle and let it do its job!
No sperm isn't impacting your muscle development.
Stupid, stupid person....what makes contact with the egg cell: the sperm cell or the muscle cell? Seriously, use your head.
By working out. The more you pump iron and use those muscles through resistance training the more muscle you will have. If you're looking for lean muscle do lower resistance for longer.
The heart is a muscle.
HI. you can use regular pump gas, as you already know. But people who drag race muscle cars sometimes use stroker engines....which can run on methane...or alchohol.
The Heart
Skeletal muscle cells,cardiac muscle cells,sperm cells
The type of active transport pump that helps muscle cells contract is the Ca2+-ATPase pump. This pump is responsible for pumping calcium ions (Ca2+) out of the cell, which helps regulate muscle contraction by controlling the levels of calcium inside the cell.

The heart is made up of muscle tissue (cardiac muscle). The muscle tissue contracts to pump blood.
