not 'stong', but in order to fertilize the female partner, it is best that the male sperm has an adequate sperm count (average is about 60 million per sq. millimeter of semen).
Their are many other factors that will contribute to the fertilization of the female, such as her ovulation cycle, her fertility, whether or not the cervix is opened or closed, etc.
Whenever the male begins to produce sperm he can get a girl pregnant.
The sperm from the male has to meet with the egg from the female
No a girl cannot get pregnant by "being eaten out" To get a girl pregnant a male's sperm must go into to the Female's sexual reproductive organ In other words he must put sperm in your vagina to get you pregnant not just his tongue.
There is no minimum length required in order to get a girl pregnant. The only requirement is that the male produces viable sperm.
No, to be pregnant a sperm has to be fused with female ovum.
No. The human male doesn't have anything the sperm to fertilize
First, this is a poorly constructed, vulgar question. Second, no. The male sperm must reach the female egg for fertilization and pregnancy.
No. Male urine does not carry semen the fluid that contains sperm. There is not possibility of pregnancy from urine.
No. No person on Earth can become pregnant without sperm.
Yes, you do.
This is something I cannot answer. If you are old enough to produce sperm, then you have enough to get a girl pregnant. A male is capable of releasing small amounts to over a billion sperm when he ejaculates (http://www.livescience.com/mysteries/080606-llm-sperm.html). So, even if you don't ejaculate, but there is semen that comes in contact with your partner, she can become pregnant.
I'd say old. Male sperm swims faster but also dies faster, so there was a good chance it was waiting for the egg.
