For some strange reason, miraculous properties have been ascribed to this rather ordinary body fluid by nearly every culture in human history. The total quantity of a man's semen was assumed to be a valuable lifetime constant from which all release had to be very frugally rationed. Though this hypothetical quantity was never determined and the quotas for rationed release never specified, loss of semen was nonetheless associated with `weakness'. Even now, it is quite common to see educated, well-placed men complaining of `weakness' from head to toe, ostensibly because of their belief that they have lost more semen than was good for them. 
It is interesting to note that human spermatozoa were first seen under the microscope by Leeuwenhoek only in 1674 and that scientific proof that the sperm fertilizes the ovum to produce pregnancy was first available only in 1779 (Spallanzani). Yet, theories about the `vital fluid' abounded centuries ago, especially the one equating one drop of semen to forty drops of blood !! Quacks and `sexologists' help considerably in perpetrating these beliefs across all strata of society even today.
The act of seminal ejaculation, likewise, is poorly understood by most. Erotic films and literature depicting `bucketfuls of cum squirted several feet' don't help matters and tend to confuse even the well - informed. Though ejaculation often occurs normally and is an intensely pleasurable sensation for most men, it is an extremely complex phenomenon that is regulated by many different systems. Hence, things often can, and do go wrong.
Let's take a look at some of the common ejaculatory disturbances. (It must be emphasized that a detailed classification and discussion of these is outside the scope of this article.)
- Premature ejaculation
- Delayed (Retarded) ejaculation
- Retrograde ejaculation
- Anejaculation
