According to a study by the National Institute of Child Health and Development and Stanford University, men who wear boxers during the day but go nude at bedtime have 25 per cent less DNA fragmentation than men who wear tight boxers day and night. Men who are hoping to be able to reproduce are advised to sleep naked, but during the day a loose pair of boxers is considered the best underwear choice for improving fertility. One third of people in the UK sleep naked according to an international survey conducted by the National Sleep Foundation. Sleeping naked not only benefits men, but women who sleep naked are less likely to suffer from yeast infections. It can also help people sleep better.

Semen and sperm are the two terms that are always used interchangeably but to your surprise, these are two different things. Many people, especially couples who are trying to conceive, find themselves in a tight spot when they are asked to undertake a semen analysis test. It is important for every couple to understand the basic difference between semen and sperm. Sperm is a motile reproductive cell, not visible with the naked eyes, which is transferred to the female reproductive system during sexual intercourse. This embryo grows into a baby. Semen is the seminal fluid which contains the sperm cells along with other plasma liquid. It is white, yellow or slightly greyish in color and viscous in consistency. It is released from the penis. Semen is responsible for transmission of the motile sperm cells into the reproductive organ of the female.
Please do not return your kit between November 23 and November 28, When was the last time you thought about your sperm? But understanding how sperm works is important. The goal of this guide is to provide a technical explanation of what exactly sperm is and how it works. A refresher from biology class: chromosomes are made up of DNA, which carries genetic information. When a sperm cell combines with the egg, which is also haploid, they join chromosomes, making a diploid organism with 46 chromosomes. Sperm cells are approximately 0. They have a few distinct parts: the head, which contains the nucleus where genetic material is carried; a midpiece; and a tail, which propels it for swimming and helps breach the egg.
