?sperm是指雄性動(dòng)物生殖細(xì)胞,也稱為精子。它們通常由睪丸中的精子管產(chǎn)生,是受精過程中必不可少的一部分。在人類和其他哺乳動(dòng)物中,sperm通常由一個(gè)頭部、一個(gè)頸部和一個(gè)尾巴組成,尾巴能夠幫助它們游動(dòng)到卵子處進(jìn)行受精。
sperm的用法:
1. Sperm is the male reproductive cell, also known as spermatozoon. (sperm是雄性生殖細(xì)胞,也稱為精子。)
2. The sperm fertilizes the egg during sexual reproduction. (在性繁殖過程中,精子受精卵子。)
3. The sperm count can affect a man's fertility. (精液計(jì)數(shù)可以影響男性的生育能力。)
4. In vitro fertilization involves combining an egg and sperm in a laboratory dish. (體外受精包括在實(shí)驗(yàn)室培養(yǎng)皿中結(jié)合卵子和精子。)
5. Some species of animals have external fertilization, where the sperm and egg meet outside of the body. (某些動(dòng)物種類具有外部受精,在這種情況下,精子和卵子在體外相遇。)
例句:
1. The doctor recommended that he get his sperm count checked to determine if there were any fertility issues.
(醫(yī)生建議他檢查精液計(jì)數(shù),以確定是否存在生育問題。)
2. The sperm and egg must join together in order for fertilization to occur.
(精子和卵子必須結(jié)合在一起,才能發(fā)生受精。)
3. The sperm's tail helps it to swim towards the egg for fertilization.
(精子的尾巴幫助它向卵子游動(dòng),進(jìn)行受精。)
4. The process of in vitro fertilization involves carefully selecting healthy sperm and eggs for fertilization.
(體外受精的過程中,需要仔細(xì)挑選健康的精子和卵子進(jìn)行受精。)
5. External fertilization is common in aquatic animals, where the sperm and eggs are released into the water for fertilization to occur.
(外部受精在水生動(dòng)物中很常見,其中精子和卵子會(huì)被釋放到水中進(jìn)行受精。)
sperm是生殖過程中不可或缺的一部分,它們具有重要的受精作用。不同動(dòng)物種類可能有不同的生殖方式,但sperm始終扮演著重要角色。通過檢測和選擇健康的sperm和egg,可以幫助解決一些生育問題。
