英語での«SPERM»の引用
spermという言葉で有名な引用文や文章
It is a well-documented fact that guys will not ask for directions. This is a biological thing. This is why it takes several million sperm cells... to locate a female egg, despite the fact that the egg is, relative to them, the size of Wisconsin.
Football is a fertility festival. Eleven sperm trying to get into the egg. I feel sorry for the goalkeeper.
In the seventeenth century, it was held by some that inside a human sperm there was a minute human being - a homunculus - that was planted inside the womb. Development consisted of the miniature homunculus enlarging and passing through birth and on to maturity-just like inflating a balloon.
My dream is to have a baby, not to adopt one, because I am not up to it and I don't feel strong enough. I want my own child, a biological child, the fruit of my sperm, conceived through artificial insemination because it wouldn't make sense for me to make love to a woman I don't love.
Just because you donate sperm does not make you a father. I don't have a father. I would never give him the credit or acknowledge him as my father.
Although each egg cell produced by a woman carries a single X chromosome, the sperm cells produced by a man carry either an X or a Y. This means, in very simple terms, that the sperm cell determines a baby's sex.
For each chromosome contributed by the sperm there is a corresponding chromosome contributed by the egg, there are two chromosomes of each kind, which together constitute a pair.
The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.
The cloning procedure is similar to IVF. The only difference is that the DNA of sperm and egg would be replaced by DNA from an adult cell. What law or principle - secular, humanist, or religious - says that one combination of genetic material in a flask is OK, but another is not?
People forget we come from an embryo and we're part sperm and part ovary. We have both sides in us.
