Of what advantage is the formation of many more sperm than egg cells?

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.

Yes. Pre-ejaculate contains sperm cells, and it takes just one to fertilize an egg.

Neither one is more important than the other, since both are required to keep the system going.  However, as the limiting factor in reproduction is how fast women can gestate young, give birth, and recover enough to gestate another child, you need far fewer males than females (as males can continually impregnate other females while pregnant females gestate young).\n\nHowever, to dispel a myth, while females do comprise slightly more of the population than males, nature produces 105 males to every 100 females in human beings.  \n\nThe difference which leads to the female majority in humans is the result of the fact males are much more likely to be victims of murder, are much more likely to die accidental deaths, are more likely to be killed in the line of work, be killed during wars or battles, are more likely to suffer from a chronic genetic disease (most are carried on the X chromosome, so while you have to have two defective copies of the gene in females in order for them to be afflicted by it and not be a carrier, males only have one copy of the genes on the X chromosome, so they need only receive one defective copy to cause them to suffer from the disease... and no, this doesn't make females biologically superior since it proves the mother of the offspring specifically had defective genetic traits which were passed on to the male offspring) etc... etc... etc...\n\nAnd nature seems to understand this, and hedges its bet by producing more males to shore up the numbers.\n\nP.S.-- We cannot clone viable sperm.  Males still have to manufacture the stuff au naturel for the process to work.

The obvious advantage of asexual reproduction is that you don't need other members of your species around to reproduce.  This is a really good thing if you want to go in and colonize someplace like a island, or maybe a recently-burned forest.  Or if your species isn't doing so great and there's just no one else around.\n\nFrom an evolutionary perspective, the 'goal' of an organism is to pass it's genes on to the next generation.  In sexual reproduction, each organism only gets to pass half its genes to its offspring.  In asexual reproduction, the parent gets to pass all its genes to the offspring.  That's great if the parent is perfectly adapted to its environment.  The problem is, it's the evolutionary equivalent of putting all your eggs in one basket - if something chances and the offspring are no longer well suited to the environment, chances are they'll all die instead of just a few.

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.

Ovum is a haploid cell, like a sperm.The ovum is rounded where as a sperm has a head, neck, middle piece and tail.The sperm is motile, whereas the egg is non-motile. The ovum may be laden with yolk depending upon how much vitellogenesis has occurred. The ovum may be 12000 times bigger than a sperm. According to the amount of yolk an ovum may be megalecithal, oligolecithal, and microlecithal. The yolk in ovum is present in the cytoplasm. In sperm however the situation is just the opposite. There is sloughing of the cytoplasm during spermatogenesis as a result it  sloughs off considerable amount of cytoplasm along with other cytoplasmic organelles.In terms of genetic content however both the sperms and ova are equivalents.

You may have less sperm than usual, but you will still have enough to get someone pregnant.  Your body is always making sperm.  I don't believe you can run out.

There are theories in some religions that the production of a drop of sperm requires many drops of blood.  Some say 40, 80 or 100 drops.  There is no scientific basis for this.  Some people will claim it is a "scientific fact" but can't tell you where the research was done.

Great question! And no, I won't call it cheating if you add another follow-up query. It's good to be inquisitive.\n\nNow, to answer your question precisely, there was no evolutionary pressure that caused polynucleated cells to form in protists as such. The factors that affect evolution viz. natural selection, genetic drift, gene migration, recombination and mutation cannot (with the exception of mutation) cause the appearance of a certain morphological trait as effectively as they can help the organism to sustain it.\n\nThe answer actually lies in the second question you asked. Yes, mitosis. To state it briefly, yes, each nucleus *does* contain an identical set of DNA. \n\nThe reason why cells are different functionally in multicellular organisms is because of the effects of certain gene mechanisms that "switch off" and "switch on" the production of enzymes under specific conditions thus, altering their functionality.\n\nNow, to answer your primary query-- as you already might be aware that during the cell-division, it is the nucleus that first divides into two: (Mitosis). Sometimes, the outer membrane of the protist fails to separate due to the lack of phospholipid membrane material. This delay in cell division back in the days of the beginning might have resulted in a polynucleated cell.\n\nThe success of this polynucleated cell may be easily justified due to the increased efficiency of the metabolism as the decentralisation of regulating power i.e. nuclear material could have resulted in division of labour and thus, in perhaps the first *ever* "pseudo"-multicellular animal.\n\nAs for your follow-up queries, I think I have provided enough detail in the paragraph above, which you can use as a *very* basic outline and explore the subject further by studying the topic in detail in your book(s).

Good question...\n\nAccording to a previous best answer to the same question:\n\n"To maintain the low temperature, so the temperature is cooler than our body. Sperm will die in heat."\n\nSeems like a reasonable answer to me.\n\n(But I think your theory is pretty darn funny!) :D

Remember that meiosis is the formation of gametes from germ cells.  Our bodies begin the process of making germ cells very early in our development, and the precursors to sperm/egg cells are in tact well before puberty.  When a woman ovulates, at the end, four of these egg cells complete the maturity stage in each cycle, but only one survives to become an ovulated egg (accompanied by 3 polar bodies).  This egg (and its complement sperm) have ONE set of chromosomes each, and upon fertilization, the zygote will have 2 copies of every chromosome, one from the sperm, and one from the egg.

No- the opposite is true: many cells form tissue.

is there more sperm produced by a male then eggs released by a female during a single month...yes. the reason is because the pollen grains have to leave the anther to make it to the ova and there's a strength in numbers going for the pollen grains.

Anthropologically & Socialogically speaking Men want to impregnate many partners to spread their seed and perpetuate the species.  Men can produce many sprem quickly.  Women on the other hand produce eggs more slowly.  Women look for a high quality mate to insure the survival of their offspring.  It's overwhelmingly the same in the animal world.  That is not to say some men look for fewer partners, and some women may have multiple partners.  It doesn't mean anything is wrong with either of them.  It's just boils down to nature and our inate genetic programming.

are you asking a question here or are you trying to preach. well i don't deny the presence of God and i am quite a religious man. but i think it was quite a absurd way to manupilate the facts as you did. u have combined the holistic approach and the scientific approach to arrive at a pseudo conclusion. why are u using that -ve ion and positive ion theory. in fact if you look at the sperm, u will find thatit is nothing but a single strand of DNA with few protiens and yeah proteins are postively charged ions but the same protein are present in ovum too and infact in larger quantity than in sperm,, so the ovum is bound to be more positively charged, if we go by your hypothesis.\n\nbetter u correct your facts before you post.\n\nP.S: i would have answered longer still and would have posted thousands of doubt in your question if i would have time and patience to go through your question completely. but unfortunately i don't think it's worth my time to waste my energy on such a stupid question. \nyou are making the mockery of GOD as well as science

These two processes are mechanisms that increase genetic diversity in organisms that reproduce by sexual reproduction.

if you can do it twice, then good, other people cant have 1 atleast. and i guess its not the quantity of the sperms that counts here, its the quality of sperm that you have... "are they fast swimmers to meet the waiting egg?". any amount of healthy sperm can make your future wife pregnant.
