No. Only one sperm is needed to fertilise the egg
No.
semen has a small amount of blood in it so the HIV is still in the blood but is carried by the semen to your partner.
Yes, semen is sticky because it contains a small amount of mucus.
There wont be any. There's many who think being cousins will make you have birth defects but this is not the case. The research show that the risk to get a child with birth defects if you are first cousins is just as small as if you were not related at all. So for second cousins there is no risk. The families where marrying cousins is common and the kids do have birth defects is families who have practiced cousin marriage for generations. Not enough new DNA.
HAS ANY BIRTH DEFECTS BEEN HAPPENED BECAUSE OF THIS CHEMICAL
Most times semen appears whittish. On some occassions, semen may appear yellowish in males. These may be due to the presence of blood in the semen, albeit it may be small amounts. The small amount of blood mixed with semen may result in the appearance of yellowish semen. Just like occassionally blood may appear in urine, called hematuria. Consult your doctor for your diagnosis.
You should never drink any amount of alcohol during pregnancy. There is research showing that very small amounts can have an effect on a fetus and cause birth defects. Drinking any amount of alcohol can cause FAS (fetal alcohol syndrome).
The benefits are a small amount of protein and glucose. Other than that there are no harmful effects of swallowing semen.
You should never drink any amount of alcohol during pregnancy. Drinking even very small amounts of alcohol can cause birth defects, miscarriage, and FAS (fetal alcohol syndrome).
Yes, but in very small amounts. When semen enters the female reproductive tract from the male, the fluid called semen is made from the fluids inside the male's body. So, if he has taken antibiotics, they would show up in the semen. The thing is that it would be such a small amount that it would be undetectable in the female's blood.
Yes semen is, normally, constantly produced. I say "normally" because a very few people have a sexual disorder where they can't produce semen. Don't worry about that though. To answer your question, semen is produced always, while eggs(female sex cell) are never reproduced.
To "pull out" means to remove the penis from the vagina before ejaculating. It is not recommended as a birth control method. "Pre-cum", or pre-ejaculate, is fluid that leaks from the penis when a man is aroused. It is a lubricating fluid that may contain a small amount of semen. Research suggests that there may not be enough semen in pre-ejaculate to make pregnancy likely. http://en.wikipedia.org/wiki/Pre-cum
