birth can be. In the beginning it takes you through the steps of how sperm travels as for looking for an egg to fertilize. Although‚ in just one teaspoon of sperm there can be over 300 million sperm cells‚ only around 40% of them are usable. The other 60% can be deformed such as having two tales. The sperm can reach the Fallopian tube within 30 minutes‚ but it can be a 2 day swim just for sperm to reach an accepting egg. After the sperm that was strong enough to make it through the rough travel have met

(commonly called sperm cells) and gametes produced by females through Oogenesis process are called oocytes (commonly referred to as ova or eggs). As gametes are formed‚ the 46 chromosomes from each parent cell (23 pairs of chromosomes) are divided through meiosis so that each gamete is haploid‚ having only 23 unpaired chromosomes. Spermatozoa‚ produced by males‚ contain a 23rd chromosome that is either an X chromosome (female) or the analogous Y chromosome (male)‚ making each sperm cell either female

reproductive system is essential to keeping a species alive‚ unlike other body systems‚ it’s not essential to keeping an individual alive. In the human reproductive process‚ two kinds of sex cells‚ or gametes‚ are involved. The male gamete‚ or sperm‚ and the female gamete‚ the egg or ovum‚ meet in the female’s reproductive system to create a new individual. Both the male and female reproductive systems are essential for reproduction. The female needs a male to fertilize her egg‚ even though it

performance of the human body. Sperm cells‚ also known as spermatozoon are reproductive cells. The main function is to fertilize the ovum. At the head of the sperm is a large nucleus surrounded by acrosome‚ the acrosome covers the head of the sperm‚ when the ovum is reached the acrosome releases hydrolytic enzymes to break through the egg wall. The nucleus is where all genetic information and enzymes are and half of the 23 chromosomes. One pair coming from the sperm cell and the other from the mother

in all living organisms. Most ova are unicellular because they are only one cell at first but becomes multi cellular once fertilized by the sperm and begin dividing. However‚ in other organisms‚ such as protists‚ they can start off as multi cellular as well. The ova is the female gamete produced by the female reproductive system and joins together with the sperm‚ the male gamete‚ during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set

widespread notion that working out lowers a man’s sperm count is wrong. This is according to two studies‚ one published in the British Journal of Sports Medicine and the other in the journal Reproduction. What Do the Studies Show? The first study was conducted at the Harvard school of Public health. The subjects were 189 men with sedentary lifestyles. The study found that men who spent more than 14 hours each week exercising had a 73 percent greater sperm concentration when compared men who exercised

Pregnancy is avoided if the male sperm does not meet the woman’s mature egg or if the fertilized egg does not become implanted in the lining of the uterus. When you intentionally do something to prevent such union‚ you are practicing “birth control”. The common method of contraception prevents the getting together of the egg and the sperm. Contraceptive pills prevent the ovaries from releasing eggs and the lining of the uterus from forming

first of all sexual intercourse in which there is ejaculation of sperms‚ by the male‚ into the female’s reproductive tract. Ejaculation is in form of semen. Sperms travel to fertilize eggs in females. This results in fertilization leading to the development of the baby. Function of reproductive system in females is to produce eggs and to nourish developing offsprings. On the other hand‚ male reproductive system is to produce sperms. Male reproductive system involves organs located inside and outside

Female tube blockages Blocked or damaged fallopian tubes prevent eggs from getting to the uterus and sperm from getting to the egg. Causes include severe endometriosis‚ pelvic inflammatory disease‚ sexually transmitted diseases such as chlamydia‚ and previous sterilisation surgery.

tightly coiled seminiferous tubules. a. The seminiferous tubules of each lobe empty sperm into another set of tubules‚ the rete testis‚ located at one side of the testis. Sperm travel through the rete testis to enter the first part of the duct system‚ the epididymis‚ which hugs the external surface of the testis. The interstitial cells produce androgens-the most important of which testosterone. Thus sperm-producing and hormone producing functions of the testes are carried out by completely different
