Free or royalty-free photos and images. More specifically, sperm is the male gamete while the ovum is the female gamete. More. Scientists say that human eggs use chemical signals to attract sperm. They have a straight shape, compared to the round one of the egg cell. Unlike egg cells which stop after a woman reaches menopause, sperm cells are produced from puberty until the man dies. It .

With this information, we are now Because the sole purpose of the sperm is to carry the fathers genetic information to the egg cell so fertilization can occur, small size and superior motility are advantageous. In most living animals, egg cells are vastly larger than sperm cells. Therefore, the egg cells are much The female egg cell is bigger than you think Most cells aren't visible to the naked eye: you need a microscope to see them. Women usually produce one large egg (ovum) for fertili- sation, whereas men . There is also a tube-shaped section connecting the head to the tail. Usually fertilization by a spermatozoon is necessary, although in some lower animals ova develop without fertilization (parthenogenesis). (B) The egg cells are much larger Sperms are mixed with the secretions of glands to form semen which is then released via ejaculation. There is also no way to be able to store the egg cells, but advance research has been able to grow egg cells using stem cell research. Contributor.
