do the benefits of sperm banks outweigh the possible problems?
474728
The only benefits I see for sperm banks are allowing infertile women procreate, selective breeding, and filtering of weaker sperm.\n\nThe negatives for spermbanks are communties' population will have unknown relative reproduciton (DNA relatives breeding with eachother without knowing), the lack of diversity in breeding pool (everyone using "good" sperm for babies), the unknown long term effects of test tube babies and fertility drugs, etc.\n\nI personally would never sell my sperm. And hope the new generations are made "naturally" so the genes randomly assort providing diversity and evolutional advancments.  Not everyone can be a genius or a superman.

Human fertility funding will assure that those people willing to go to great lengths to have a child will be among the ones populating the world. These people will be more likely to provide advantages to a child, which will make it a more productive citizen.\n\nWith the falling rates of fertility in industrialized nations, the rate of reproduction will be much higher in poorer nations, therefore reducing the ratio of well-educated to poorly educated people, leading to an overall decline of quality of life worldwide. With fertility research, this ratio will be improved. (Doesn't mean those people will help anyone else, but it's a decent argument anyway.)\n\nThose two are the only ones I can come up with off the top of my head. You've got a tough position to support, but, as Rob Schneider says, "You can do eeeet."

There is a lot more protections built in to protect the testes than most realize, but they may not be in the design or style YOU think is protective.  The testes are EXTERNALLY located (in scrotum) to protect them from hyperthermia.  Being external is cooler and that is a protective design feature. In fact, oneis lower than the other to prevent them from getting too bumped whilenext to each other, esp between the legs. In fact, both the Dartos and Cremaster muscles help with this too, adjusting the closeness of the testes to the body based on the environmental temp, thus keeping the testicles the critcal proper temp to keep meiosis or sperm production going.  In fact, during the fight or flight mechanism, inc during climax, these muscles adjust the testes, which are pulled up close to the body to help protect them.  Some males will also tell you that the testicles can even go back up into the inguinal canal a bit so that they are protected from harshness of an uncomfortable hard surface like a bicycle seat or motocross ride on a dirt bike (hopefully not for too long, so as to prevent hyperthermia) or even to protect them from hypothermia.  Another protective device is the production of a HUGE number of sperm throughout life and per ejaculate.  A normal male can have 250-300 million sperm per ejaculate.  A huge number of sperm die with each ejaculation, only a few can survive the trip to the egg.  The testes are also covered with a very tough connective tissue called the tunica albagenia, and it helps give them their characteristic "egg" shape. Another protection is the "wet dream" mechanism.  IF a male has not ejaculated recently, an unconscious wet dream can help release some old sperm so that a fresh batch is kept ready and available.  In addiition, if a male has had too long or hot of a jacuzzi or has worn too hot-tight pants-underwear, or has been exposed to something potentially toxic in his environment, etc, this unconscious ejaculation can help get rid of a batch that might be defective or a weaker quality.  As it is, about 20% of a"normal" males sperm are visually defective under the microscope (with 2 heads or 2 or three tails, etc) but there is opportunity for new batches on a regular basis.  Female eggs, on the other hand, have the maximum number at the fetal stage and the number of her eggs is decreasing all her life.  The design of all the human body is a magnificant creation!  Thousands of mechanisms are included to keep the body in homeostasis, inc many to keep the testes and sperm protected from harm.  The chemical nature of semen is such that the sperm are protected too. There are so many protective mechanisms! The fact that they are SO sensitive is also a protective mechanism. Males keep that on their mind a lot and will usually do a lot tokeep the "family jewels" safe from damage.

Yes, some sperm escape.

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.

It is possible that you had some sort of issue as a child such as retracted or udescended testicles, which can cut off the circulation and hinder sperm production.  I would see a urologist about it.

its all depends on your profile, you will be getting much more higher if you have a superb academic(phd/MBA) background,arts/musical and philosophy,achievements, your current job and your looks.With these qualities, you can even demand the price and how often you want to sell your sperm as your sperm will be highly in demand. Certainly no one wants to buy sperm that comes from an ex-killer, dude!

i would suggest consulting with a genetic counselor to discuss your particular situation. see info below...

As a matter of fact, this is true.  It was reported in a recent Reader's Digest in their Medical Updates section.  No, they don't affect women.  The issue was the heat generated by the laptop causing a drop in sperm production.  It is not a theory, but a fact.  Of course, like so many things, two years from now they may come out with a study that says it isn't as bad as they once thought.

The government is unfortunately less inclined towards preventing problems, such as overpopulation, and more inclined towards fixing current ones, such as providing food for the ten children in a family.  I definitely hear what you're saying though, and I think a tax benefit should be given as incentive for not having children.  Talk to your congressman.  Unfortunately, though, I doubt you'll make any progress on this problem under the current administration.

As a male (I'm presuming), you wouldn't contribute any mitochondria to the offspring. You may potentially add variation into the population which, if detrimental, would be selected out of the population and thus leading to little negative long-term effects. The worst-case scenerio would be that you carry a dangerous recessive allele that gets reintroduced to the population due to consanguineous mating (mild inbreeding), but chances are such an allele would be selected out entirely over many generations.

I think that, in addition to the answer provided above, that there are more fertility problems that we are aware of.  Twenty or thirty years ago, nobody discussed fertility issues, and we didn't see advertisements about fertility clinics.  Now that those treatments are available, it's brought fertility issues into the public eye more than ever before.

just because you have a low sperm count doesn't mean they are unhealthy..one of the main reasons guys have low sperm counts is because they are blowing their loads too much and the sperm takes time to replenish.

Yes, the excessive masturbation always affects adversely on sperm production. But you can replenish the sperm by eating oysters, meat, eggs, and drink a lot of milk.

yes your nuts needs plenty of room to be productive!! It's okay if you are a healthy person. but for people who has low sperm count, they need to do everything possible to increase their production.

It depends. It allows the body time to heal in some cases. Some are even put in this situation (artificial or induced coma's)by doctors, in those situations its a good thing, beneficial. I suffer from Lupus which can in severe cases cause kidney failure, stroke brain disease etc. I have told my family and have a living will that if i am ever in the situation where there is no hope I do not want to be kept alive by machines. I have 5 kids. I would never want them to spend, or feel obligated to spend their days watching there mother like that. With that said if it were one of my kids on life support I'd probably fight them turning off the machine in desperate hope for the breakthrough or miracle cure. It's a hard question. I guess the answer is both
