|"let us divide the creation of the foetus overall into four periods of time.<BR>''The first'' is that in which. as is seen both in abortions and in dissection, the form of the semen prevails [compare with the Islamic nutfah/semen stage]. 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 [compare with the alaqa/bloodclot stage], and heart, brain and liver are still unarticulated and unshaped yet have by now a certain solidarity and considerable size,<BR>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.<BR>''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 [compare with the mudghah/morsel, formed and unformed stage]. 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.<BR>''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."<ref>Corpus Medicorum Graecorum: Galeni de Semine (Galen: On Semen) (Greek text with English trans.

"... 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 [compare with the kasawna al-'ithama lahman/clothed the bones with flesh stage], 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."<ref>Corpus Medicorum Graecorum: Galeni de Semine (Galen: On Semen) (Greek text with English trans.

Galen said that the embryo is initially formed out of the male semen mixed (μίγνυται) with what he called the female semen, which also forms an additional membrane entwined (ἐπιπλεκονταί) with that of the male semen. He believed that blood from the woman is subsequently drawn in via the uterus and membrane, and this combined material literally goes on to form the fetus.<ref>Philip De Lacy (editor and translator). “Galen: On Semen (Corpus Medicorum Graecorum 5.3.1.)”, pp.85-89, Berlin: Akademie. Verlag, 1992</ref> This will be explained a little more later. Unlike Galen (and before him, Hippocrates) with the two-semens theory, Aristotle believed that there was only a male semen, which does not itself provide material for the embryo, but triggers its formation from menstral blood.<ref>Philip De Lacy (editor and translator). “Galen: On Semen (Corpus Medicorum Graecorum 5.3.1.)”, p.65, Berlin: Akademie.

The same thing is reported in Berakoth 60a.<ref name="Berakoth 60a"></ref> Notice also a two-semens theory again. In most versions of this hadith the determining factor in resemblance is whose water (m<U>a</U>a i.e. semen) preceded (sabaqa) the other person’s water. In other versions it is whose water is on or upon (‘ala) the other’s, which is closer to various Greek theories in which resemblance or gender is caused by semens prevailing upon each other.<ref>Iain M.

Democritus of Abdera says that it [gender] is determined in the womb whether the offspring is to be male or female. He denies, however, the theory [of Empedocles] that heat and cold are what make the difference; it depends, he thinks, upon which of the two parents' generative fluids prevails--i.e., that part of the fluid which has come from the distinctively male or female parts [rather than the part which has come from the body as a whole]. Of the two theories that of Democritus is the better; for he is trying to discover and specify the exact way in which the sexes become differentiated; but whether he is right or not is another matter.

Based on pp.91-93 and p.101, he seems to mean here the thicker male semen, which he says provides some of the material for the fetus as well as “power” or “motion” to the material. He says that the female’s semen provides nutriment to the male semen, and also has a weaker “power”, supplemented by that of her blood, to cause any resemblance of the child to the mother.<ref>Philip De Lacy (editor and translator). “Galen: On Semen (Corpus Medicorum Graecorum 5.3.1.)”, pp.165-167, Berlin: Akademie.
