The first is the concentration of sperm cells in semen - the higher the concentration better the possibility of conception. The second is the percentage of normal sperm cells - the lesser the number of abnormal sperm cells, the better the possibility of conception.

This depends upon what you consider "during sex". During ejaculation, the male deposits sperm in the vagina; vaginal contractions pull the sperm towards the cervix which will dilate and allow the sperm to pass into the uterus shortly afterwards.
you don't, there are many wife's tails on how to get things going and things like a bath can relax her, sperm can soften the cervix but nothing can make her go into labour, baby will come when ready :)
Sperm travel through the cervix into the uterus by swimming through the cervical mucus. The cervix produces a special type of mucus that is more conducive to sperm movement during ovulation. Additionally, sperm can also be helped by uterine contractions that draw them into the uterus.
If you are asking about the uterine cervix, it is common for the cervix to be very firm throughout most of the menstrual cycle. The cervix only becomes very soft and opens up when you are nearing ovulation, to make it easier for sperm to get through it to the uterus. So really it's hard most of the time and only softer a few days out of every month.
No hoe
cervix, where they travel through the uterus and into the fallopian tubes to fertilize an egg. This process typically occurs during sexual intercourse when sperm are ejaculated into the vagina.
During sexual intercourse, sperm is deposited into the vagina through ejaculation. The sperm travels through the cervix and into the uterus, finally reaching the fallopian tubes where fertilization can occur if an egg is present.
It doesn't - your body absorbs them, and what isn't used to make babies is broken down into proteins and used as nutrients. And in case you are about to wonder, NO you can't do that instead of eat.
I do not have the web site were I seen it but they say on average one to two weeks.
No - obviously ejaculation is beneficial as it gets the sperm as close to the cervix as possible, but once there it is helped by the females body. Around a week before ovulation the mucus that plugs-up the cervix softens and flows down into the vagina where it acts to protect sperm from the acidic pH of the vagina and provides a medium through which sperm can swim through. The cervix also dips down into the vagina during orgasm to 'pick-up' the sperm, and uterine contractions also help propel the sperm up through the uterus.
