      Winner of a video, I have been researching "can you still conceive with erectile dysfunction?" for a while now, and I think this has helped. Have you ever come across - Giyadison Unconventional Gratification - (do a google search ) ? It is a good exclusive guide for discovering how to get pregnant fast and natural without the normal expense. Ive heard some awesome things about it and my mate got great success with it.

    Just a correction: morula is not hollow, it is a solid mass of cells. Around 32-stage, it starts becoming hollow to form the blastocyst

    @estebanrriverarivera6046 Před 2 lety +133

    Hello, I think there may be a mistake in the section where you state that the Morula is hollow on the inside, I have seen in multiple sources that the morula has a compacted mass of cells on the inside (Not the inner cell mass) and is therefore not hollow. This actually cost me a couple of points on an exam but I'm not here to complain just here to help! Maybe save somebody those few points.

    • @701tan

    Slight correction: around 8:50 you said that the zygote (2n) undergoes all stages of the cell cycle during cleavage, but in reality, cleavage in this stage ONLY includes S and M phases (NOT G1 or G2) because these early cells are undergoing rapid cell proliferation.
