Masculine men's sperm fewer

Australian researchers, who examined the number of normal sperm cells in men said, he with masculine voice or low-pitched voice was a bit of male sperm is more high-pitched voice.

Low-pitched male voices are generally considered more masculine by women, has decreased the concentration of sperm in the ejaculate.

An evolutionary biologist from the University of Western Australia said, the low tone was an effect of testosterone. However, high testosterone levels can actually suppress sperm production.

Sperm count is one important factor to support the success of fertilization. To find out whether the sperm that have qualified, it is necessary the analysis of sperm and seminal fluid in the laboratory.

In the process of this analysis there are some things that will be assessed by a physician, among others:

- The amount and viscosity of cement

Produced semen from each ejaculate between 2-6 millimeters (1/2-1 teaspoon). If the amount is less, it is feared the number of sperm cells is not sufficient to reach the egg. However, too much cement can also dilute the concentration of sperm. Ideally, semen should be quite thick and mengencer about 10-15 minutes post-ejaculation. Seminal fluid is too thick will make it difficult sperm to swim.

- Morphology

This is an analysis of the shape, size, and appearance of the sperm cells. A test of 200 sperm cells should not be there any defects that could be called normal.

- The concentration of sperm

Also called sperm density, this is the number of million sperm per millimeter of seminal fluid. Amounted to 20 million sperm per milliliter are considered as normal.

- The movement of sperm

Measured the percentage of sperm that can swim and also achieve the goal. One hour after ejaculation, at least 50 percent of sperm should be swimming forward in a straight line. source: dechacare.com
