    Search Aristotles works for he word "Sperm" and you come up with again a very long list of hits:

    Of animals otherwise, a great many have, besides the organs above-mentioned, an organ for excretion of the sperm: and of animals capable of generation one secretes into another, and the other into itself. The latter is termed ‘female’, and the former ‘male’; but some animals have neither male nor female. Consequently, the organs connected with this function differ in form, for some animals have a womb and others an organ analogous thereto. The above-mentioned organs, then, are the most indispensable parts of animals; and with some of them all animals without exception, and with others animals for the most part, must needs be provided.

    All sanguineous animals eject sperm. As to what, and how, it contributes to generation, these questions will be discussed in another treatise. Taking the size of his body into account, man emits more sperm than any other animal. In hairy-coated animals the sperm is sticky, but in other animals it is not so. It is white in all cases, and Herodotus is under a misapprehension when he states that the Aethiopians eject black sperm.

    Further, animals differ from one another in regard to the time of life that is best adapted for sexual intercourse. To begin with, in most animals the secretion of the seminal fluid and its generative capacity are not phenomena simultaneously manifested, but manifested successively. Thus, in all animals, the earliest secretion of sperm is unfruitful, or if it be fruitful the issue is comparatively poor and small. And this phenomenon is especially observable in man, in viviparous quadrupeds, and in birds; for in the case of man and the quadruped the offspring is smaller, and in the case of the bird, the egg. For animals that copulate, of one and the same species, the age for maturity is in most species tolerably uniform, unless it occurs prematurely by reason of abnormality, or is postponed by physical injury. In man, then, maturity is indicated by a change of the tone of voice, by an increase in size and an alteration in appearance of the sexual organs, as also in an increase of size and alteration in appearance of the breasts; and above all, in the hair-growth at the pubes. Man begins to possess seminal fluid about the age of fourteen, and becomes generatively capable at about the age of twenty-one years.

    Er, Aristotle explained how ALL life comes from eggs - and many eggs have to be fertilised and he also explained how the male contributes to the majority of the off-springs features.

    Kefah, there might be a god, sure, but nobody could possibly know whether there is a god and nobody could possibly know whether there is no god.

    I am an agnostic atheist - that means that while I believe quite firmly that there is no god I cannot possibly know that there is no god.

    And besides - when there is belief in gods there emerges all sorts of arbitrarily invoked and awarded licenses for all sorts of immoral acts - basically, when there is belief in gods then any form of immorality is permitted - and so even if there was a god I think in the interest of better morals it would be better for mankind not to believe there are any gods.

    Aristotle thought that in Humans the egg exists in the woman as a sort of blood clot.

    "Aristotle believed that humans originated from the action of male semen upon female menstrual blood which leaves us with something of a dilemma. If we translate alaqa as "clot" it means that the Qur'an is completely wrong about human development, since there is absolutely no stage during which the embryo consists of a clot. The only situation in which an embryo might appear like a clot is during a miscarriage, in which case the clotted blood which is seen to emerge (much of which comes from the mother incidentally) is solidified and by definition no longer alive. So if ever an embryo appeared to look like a clot it would never develop any further into a human; it would be a dead mass of bloody miscarrying flesh. Since Muhammed had several wives it is entirely likely that he would be very familiar with miscarriages. Alternatively it could be hinting at Aristotle's incorrect belief that the embryo originated from the combination of male sperm and female menstrual blood."


    "So far from bones being clothed with flesh, it would be more accurate if the Qur'an had said that muscles started to develop at the same time as bones, but completed their development earlier. The idea that bones are clothed with flesh is not only scientifically completely false, but is directly copied from the ancient Greek doctor Galen, as we shall see shortly"

    The account of the different stages in embryology as described by the Qur'an, ar-Razi and al-Quff is identical to that taught by Galen, writing in around AD 150 in Pergamum (Bergama in modern Turkey). Galen taught that the embryo developed in four stages as detailed below.

    Here is what Galen said:

    "But let us take the account back again to the first conformation of the animal, and in order to make our account orderly and clear, let us divide the creation of the foetus overall into four periods of time. The first is that in which. as is seen both in abortions and in dissection, the form of the semen prevails (Arabic nutfah). At this time, Hippocrates too, the all-marvelous, does not yet call the conformation of the animal a foetus; as we heard just now in the case of semen voided in the sixth day, he still calls it semen. But when it has been filled with blood (Arabic alaqa), and heart, brain and liver are still unarticulated and unshaped yet have by now a certain solidarity and considerable size, this is the second period; the substance of the foetus has the form of flesh and no longer the form of semen. Accordingly you would find that Hippocrates too no longer calls such a form semen but, as was said, foetus. The third period follows on this, when, as was said, it is possible to see the three ruling parts clearly and a kind of outline, a silhouette, as it were, of all the other parts (Arabic mudghah). You will see the conformation of the three ruling parts more clearly, that of the parts of the stomach more dimly, and much more still, that of the limbs. Later on they form "twigs", as Hippocrates expressed it, indicating by the term their similarity to branches. The fourth and final period is at the stage when all the parts in the limbs have been differentiated; and at this part Hippocrates the marvelous no longer calls the foetus an embryo only, but already a child, too when he says that it jerks and moves as an animal now fully formed (Arabic ‘a new creation’) ...

    ... The time has come for nature to articulate the organs precisely and to bring all the parts to completion. Thus it caused flesh to grow on and around all the bones, and at the same time ... it made at the ends of the bones ligaments that bind them to each other, and along their entire length it placed around them on all sides thin membranes, called periosteal, on which it caused flesh to grow."
