Question
how many nerves are there in the human body. Also can a
man get pregnant.
Hi Bhagat: Thanks for your questions.
The nervous system is usually divided into the peripheral ns (nerves of the body) and the central ns (brain and spinal cord). Although it is hard to estimate, the nervous system consists of about a hundred billion nerve cells.
Here is a good website for more information:

As for male pregnancy. Currently, it is not occurring. Men do not have the necessary organs (uterus) to carry a fetus to term. They also do not naturally produce the correct hormones to maintain a pregnancy. Having said that, experiments are underway to alter male anatomy and physiology to make it happen.
Let’s just say that it is not happening regularly. Who knows what the future may bring?
I hope this answer has helped you. Please write back if you have more questions.
