do sperm seek out the egg or just hit it by chance?

actually there are about 50 million in each load, and yes they seek it out

Probably externally, like lots of other fishes.  They male releases the sperm, and the female releases the egg.  The sperm drifts towards the egg, and then the egg is fertilized.

Attempting to remove the sperm cell from the semen would most likely kill the cell.  What would you do once you removed the sperm cell? Wash it out so no semen remains?\n\nThe semen is what activates the sperm cell so it starts to move its tail. Semen is its "natural habitat" in order for the cell to be reproductively viable.  I do not know of any way to accomplish this feat and I do not think any sane doctor would even try to artificially inseminate an egg using sperm from a know HIV patient.

Any contact of semen even on or near the vaginal opening can get someone pregnant, so penetration really makes no difference. Not all women can feel a man ejaculate so it is nothing to be worried about.

"Rapid" sperm travel 25 microns/second, or one sperm length every 2 seconds.  "Slow" progressive sperm swim 5 - 24 microns / sec. \n\nRapid sperm are pretty quick.  Slow sperm, not so much.  \nPS - They figure it out by watching them swim under a microscope that has a little micron ruler.

Sperm count is generally determined by putting a semen sample under a microscope and.. well, counting.  :-)\nNot all 4 or 5 million of them, but they take counts in a number of small area, then take the average and multiply it up to a standard volume \nYes, there are computerised methods to do the same thing, but the principle is pretty much the same.\n\nSo, if you happen to have access to a good microscope and are very patient, you could check it yourself... but it's a lot simpler just to go to a fertility lab and pay them to do it for you.

In general, sperm cells have to swim to find the eggs. So producing more of them increases the male's chance of fathering offspring. If Yellow Perch lay eggs in the water rather than have internal fertilization, then males might compete to have their sperm get to the eggs. This of course favors making as many sperm cells as possible.

It searches for an egg to fertilize. It only takes one sperm, but thousands can enter your body. The ones that don't make it just come out when you pee.\n\nSorry smarts20, but you are wrong. The ovary releases an egg during ovulation and travels down the fallopian tubes into the uterus where it hopes to be fertilized and become implanted in the uterus. If the egg does not become fertilized you have your period.

Fertilisation occurs before formation of the shell. However, many times, birds lay eggs that are not fertilised (take chicken eggs for example).

You need to get the sperm to the eggs and with an "army " of sperm, its more likely that some of it will eventually make it past all of the factors that might cause it from not reaching its target... such as when pollen is on a pollinator, some of it is usually lost in flight or just in the regualr movement of the animal that does that job. some plants are pollinated by the wind and the more that is released increases the  chance that some of it will reach the egg. Eggs are usually very close to the adult version of the plant or even within the plant before they are fertalized so they are mainly stationary... with more chances to reach the egg it increases the fecundity.

It all depends on if they are still producing viable sperm.  In order to know for sure they would have to be tested by there doctor.  There is an at home test kit available, but it has been deemed inaccurate so he should see his doctor.

Your docs are indeed right, a certain amount of malformed sperm is not unsual.  But to answer your question, let me give you abit of the bigger picture.  Fertilization, the interaction of the sperm and the egg cell (or ovum), in which the genetic material of the sperm enters the ovum, is a rather complicated process.  There is a lot that can go wrong, but there is also a lot that can go wrong way before the sperm actually reach the ovum.  In your everyday sperm analysis what people check for are primarily: (1) sperm number, (2) morphology, (3) motility.  what does this mean?\n\n(1) Sperm number:  while it is not necessary to have billions and billions of sperm to achieve pregnancy, it helps to have a certain amount of actual spermatozoa, that is, the actual sperm cells that will eventually release their genetic material into the ovum.  Now, the amount of the ejaculate is not necessarily indicative of the number or quality of sperm cells.  That is because the spermatic fluid is largely produced by accessory glands such as the prostate.  Your husband could theoretically have a large volume of ejaculate but few sperm, which would be bad.  Apparently, your doctors are not concerned about numbers, so you don't have to worry about this.\n\n(2) Morphology: Now, morphology is closely connected to the third point, motility.  Bascially, what one is looking for is a proper head shape, a nicely beating flagellum (or tail) and not too many spermatozoa that are fused by the heads etc.  Malshaped sperm cells can have significant ramification.  Since the little guys have to swim quite a distance to meet the ovum, they really need to be in "good shape".  (I mean this rather literally.)  If they are malformed, they simply cannot swim well enough.  Malformed cells often will end up swimming in circles, which is bad.  However, the good news is, while your husband has a slightly increased number of malformed sperm cells, there are still enough well shaped cells around to achieve the feat.  Only two out of one hundred cells are malformed.  Nothing to worry about.\n\n(3) Motility:  This is a tricky bit.  You see, the sperm cells may be well shaped, and yet not good swimmers.  There can be multiple reasons for it, one of them is the maturation of the cells in the epididymis, where spermatozoa receive the ability to beat their flagellum well, another a process called capacitation.  Capacitation takes place ones the sperm are ejaculated into the female (sorry about the technical language).  The sperm will adhere to the uterine wall and sit there for a while undergoing significant biochemical changes.  As an effect, the sperm flagella begin to beat really hard.  This is called hyperactivation.  When the flagellum beats strongest, the cell is released.  You can imagine it a little bit like a toy car you have to wind up.  When it is all wound up and ready to go, you let go.  Similarly here, the sperm are let go when ready.  Now, in some patients this hyperactivation doesn't work.  for whatever reasons well formed sperm simply do not get hyperactivated and thus cannot swim well.  To check for the first problem (whether the cells matured right in the epididymis) sperm cells are tested for how they do in swiming up against a density gradient.  Now, I don't think that any of this matters for you either, because your husband's doctors didn't mention motility.\n\nWhat to make of all this?  First off, try to relax.  I know it is difficult, but it won't help for you to worry so much about the success rate.  Enjoy your love and focus on one another and on making love rather than on making a baby.  There can be numerous other causes for why it has not yet worked for you to get pregnant, but according to the statistics your main problem is properly worrying too much.  \n\nI hope this helps.  Good luck!

Each cycle one of your ovaries releases an egg (called ovulation). The other ovary remains dormant meaning it doesn't do anything. The egg travels down into your fallopian tube (part that connects the uterus to the ovaries). Then if pregnancy occurs sperm fertilizes the egg and then the "baby" moves down into the uterus where it grows until it is born. During pregnancy both ovaries do not ovulate anymore until postpartum (after the baby is born). Usually the first ovulation (releasing of an egg) occurs 2 weeks to 3 months after the baby is born. If the mother breastfeeds exclusively then sometimes ovulation won't occur again until the baby is a few months old to a year old.

Have sex.\nDiet is very important both for male (sperm motility) and female.  Make sure you are healthy.  Also, look into basal thermometer- and have sex when you are ovulating.  You will not get pregnant if there is no egg involved.\nDon't have sex too much (2 or more times a day); save that sperm for ovulation.

As Long as sperm can come out it can get you pregnant. The question is do you want to curse your offspring with small penis genes. I wouldn't.

the sperm is the tadpole lookin things and the semen is the stuff that a guy ejaculates. Yes semen definatly gets you pregnant as does the sperm.

It depends on how much the sperm  drink. No actually, it turns out that men who regularly drink coffee have sperm with better strength and endurance than men who do not drink coffee.
