what magnification do you need to see a human sperm?

100 but 400 is better

On average, the ejaculate of a human male contains 10,000,000 sperm.  10,000 will make it to the uterus.  100 will make it to the fallopian tube.  10 will make it past the zona pellucida (which surrounds the egg).  1 will fertalize the egg.  So the chances of any given sperm fertilizing an egg is about 1 in 10,000,000 (i.e. 1 in 10 million).  However, that's assuming the sperm are released inside a woman's vigina and she's not using any form of birth control.  If you're talking about the general population of all sperm it's a whole lot lower.

the sperm count must at least be 30million/ml.Ur friend should check a doctor cz he cannot solve this problem by himself.He needs to be checked up inorder to find the problem.It might be due to the spermduct or improper sperm secretion from the seminiferrous tubule...there are plenty.........See a doctor

magnification = apparent size/actual size\n\nso actual size = apparent size/magnification.\n\nso if it appears to be 8mm under your microscope,\nactual size = (8/1000) mm\n                  = 8 micrometres or microns.

How do you know how much sperm you are producing?  Only a lab test can determine your sperm count.  If you are simply talking about increasing semen production, which carries the tiny bit of sperm, you do need to be healthy and eat healthy, exercise regularly and all that.  Unfortunately, there is not a lot to do to increase semen volume overall.  Recent studies do show that guys with large balls do produce more semen, probably a genetic breeding result.  If you have average size balls, you wil probably have an average load of semen.

You take your chances. It's the father who determines the sex, and it all depends on which sperm gets to the egg first... the boy sperm or the girl sperm.

The color, texture, and quantity — not to mention the force of ejaculation — vary greatly. Based on outward appearance we are all amazingly similar: virtually everyone has eyes, ears, a nose, and a mouth in the same place. But semen just doesn't work that way. \nJust like penis size, ejaculation volume and force are highly variable from individual to individual. Most guys want to ejaculate more semen with more force.\nIf you've done exercises like Kegels For Men, yes, it may have increased your distance — but probably not your volume. There's a *huge* variation from person to person with regard to ejaculation force as well as volume, and neither has anything to do with anything important (such as having children).\n\nA lot of guys would love it if they could make like one of the characters in Scary Movie and ejaculate so much that they plaster their girlfriends against the ceiling. And although that won't likely be happening anytime soon, it's believed that wheat germ increases seminal output. Bon appétit.\n(Butter's note: I only tried it once and it thickened my load like I've rarely seen before. Eat with oatmeal for better results)\n\nAmino acids, if taken regularly, are generally believed to increase ejaculate fluid. On the other hand, zinc seems to improve both the amount of sperm produced as well as the sperm's ability to move spontaneously and independently. Together with amino acids, this will increase normal sperm count and volume significantly. \nAmino acids are believed to increase ejaculate fluid (not the amount of actual sperm necessarily) if taken regularly. Some amino acids include:\n\nL-ARGININE HCL\nStudies show sperm and semen volume doubles, fertility improves (even among men with low sperm counts or poor sperm motility), and sperm health and activity increase with supplementation. Arginine is found in high concentrations in nuts and seeds like peanuts and almonds. It can also be found in chocolate and raisins. Some Natural Sources: Nuts, sunflower seeds, sesame seeds, chocolate, popcorn, raisins, brown rice, carob, gelatin desserts, oatmeal, whole wheat bread, and protein rich foods. \n\nL-LYSINE\nResearchers find that this amino acids plus zinc increases sperm produced, stimulates testosterone production, and improves semen quality.\n\nEPIMEDIUM SAGITTATUM\nSometimes called "horny goat weed," this botanical boosts libido and testosterone levels for greater sperm production for a strong ejaculation.\n\nZINC OXIDE\nHas been shown to increase number of sperm and sperm motility by 80% to 200% by aiding testosterone synthesis.\n\nL-CARNITINE\nThis amino acid is found in high concentrations in healthy sperm. Proven to significantly increase the percentage of highly motile sperm.\n\nCATUABA BARK\nBrazilian herb that strengthens the libido, and nourishes the entire male reproductive system.\n\nPUMPKIN SEED\nSupports prostate health and hormonal production. While they may not readily increase sperm volume, they do enhance prostate health and testosterone production.\n \nMACA\nLegendary South American botanical proven to promote libido, potency and energy.\n\nGinseng Y\nohimbe bark\nVitamin C, E\nMagnesium\n(Butter's note: Lecithin added daily increases amount, not thickness)\n\nZinc has been shown to improve both the amount of sperm you produce and the sperm's ability to move spontaneously and independently. Coupled with amino acids (see above), this will increase sperm volume significantly.\n(Butter's note: Not as miraculous as they make it sound, but regular zinc intake (50mgs a day) does increase quantity somewhat.)\n\nWhatever a pill company's claims are, you can probably do just as well with zinc and lecithin supplements.

I swallow sperm all the time. At first you may not like the taste, but pretty quick ya get used to it. After awhile I got to where I LIKE the taste. Have him eat and drink something sweet 5 or 6  hours before hand. Guys all taste a bit different, but this'll make it more palatable.

A 'spermatozoon', 'spermatozoan', or 'sperm cell'.  (I believe that any of these is more correct than 'sperm'.)\n\nIncidentally, if it had an X chromosome, then it could either be a sperm cell or an egg cell (ovum).

Your testicles should be about the same size. One often is lower than the other, which is more a reflection of where it is at in the sperm producing cycle.

Sex is always good.

its suppose to be two teaspoons (give or take the amount of times you...).  but the number of "sperm" can be higher or lower depending on your health and lifestyle.

None, really, unless the man or woman is malnourished.\n\nFor information on the subject, try reading _Fertility, Cycles, and Nutrition_ by Marilyn Shannon.  I haven't read the book, but I have seen it recommended.

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.
