There is no reliable "natural" method for ensuring the sex of a baby. As sperm are responsible for the baby's sex, it would be necessary either to ensure that the male produces sperm carrying the appropriate chromosomes for the desired sex. There is no way of doing this. Optionally, it is possible to increase the concentration within semen of sperm carrying the coding for one sex or the other, as the two different kinds of sperm are of different weights, and semen can be processed in a centrifuge to separate lighter from heavier sperm. This does not guarantee results, but increase the chance of fertilisation by a sperm of the desired sex. Of course, this process requires use of a form of IVF. This process is difficult and generally only used when serious adverse results are expected if a child is of a particular sex. Filtering techniques are of no use, of course, for men who only produce viable sperm for one sex but not the other. The simplest solutions are adoption or being content with whatever you get.
A condom's primary function is not to kill, but to block the semen from progressing into the womans vagina; however, there are condoms that are coated in a spermicidal fluid that will kill the semen on contact without harming you or the other party. Such contraceptive measure though, do not guarantee the prevention of STD's. Take care, and stay safe.
The male reproductive tract carries sperm. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, vas deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra.
If semen came into contact with the vagina, there is always the chance that you may become pregnant. A sensation of wetness makes no difference whatsoever.
If you have reached puberty the sperm is mature. Before puberty you have semen but no sperm. To see if the sperm is no good when it comes to impregnate someone that can only be seen in a microscope.
The count is made if you have enough sperm to fertalise a women, sperm comes out with the semen.
It usually does unless the man is infertile.
Cows don't produce sperm nor semen. Bulls do. The semen that comes from bulls is white, with maybe a slight yellowish tinge.
Semen comes in many consistencies. There is no way to tell from looking at the semen if it is healthy or not, or if the sperm are viable or not. Sperm is microscopic, and any pathogen in the semen such as a virus or bacteria is also microscopic.
You can produce sperm in your semen once puberty has begun. Before puberty begins you will not be able to produce semen. The testes will produce the sperm when the secondary sexual characteristics are ready.
When you masturbate, you ejaculate "semen", which consists of seminal fluid that comes from your prostate, and sperm, which comes from your testicles.
Yes before puberty you can produce semen. But this semen may not contain any fertile mature sperm.
Sperm and semen production officially starts when they reach puberty, but bull calves can also start semen production even before they are born.
ofcoures you should no this if you are old enough to even have sex but it is SPERM!!! AKA CUM!!
Semen is the collective of sperm and seminal fluids. Clear semen has very little or no sperm, hence its lack of colour. Semen that has sperm in it, will be white.
Seminal fluid is added to the sperm to make semen.
