The first stage is the formation of the acrosome, which is an enzyme-rich structure covering the head of the sperm. This is essential for fertilization. Then a tail develops for forward propulsion and mitochondria (energy generators for the cell) form in the midpiece of the sperm. By now, the work of the Sertoli cells in nurturing the primary spermatocytes through the process of spermatogenesis is complete. As these processes have occurred the developing cells have moved closer and closer to the lumen of the seminiferous tubule. Finally they are extruded and released into the tubule. In humans this whole process of spermatogenesis takes 64 days.
Once in the lumen of the tubule, the sperm are washed away by secretions from the Sertoli cells, and eventually reach the confluence of all the tubules in the single, highly-convoluted tube of the epididymis, which eventually drains into the vas deferens. The passage of sperm from the seminiferous tubules of the testis to the vas deferens takes about 12 days. During this time the sperm are subjected to major environmental changes due to testosterone-dependent secretions within these tubes. As a result, sperm not only acquire the ability to swim (on leaving the testis they are only capable of an infrequent twitch), but they also change in the way they utilize and break down energy substrates, and finally reach full fertilizing capacity. Sperm obtained before their passage through the epididymis are incapable of fertilizing an egg even if implanted directly.
A man ejaculates* when he has hit his sexual peak, therefore an involuntary muscle contraction in the penis releases sperm at the end.
That is how a man sperms.
Sperm is produced along with semen when a man ejaculates after stimulation of the penis. Men may ejaculate involuntary during puberty.
The most common way a guy releases sperm is by ejaculating.
Women do not produce sperm ! Women produce eggs - which are developed in their ovaries !
Women don't have sperm.
Any sperm can get a women pregnant.
A women is not capable of releasing sperm. Women release eggs. Only a male (man) can release sperm from their body. When sperm and a fertilized egg combine, a baby is made.
women hold the sperm to produce a baby.
sperm, lots and lots of sperm
Then she touches sperm...
From what I know, all the guys have to do is release the sperm inside a women and it goes into their womb.
Absolutely not. Women can only become pregnant when sperm enters the vagina.
Women dont produce sperm
No.
Women do not have sperm. They only have eggs. The male releases sperm when he ejaculates.
