I don't even know what my med school journey will be like without the help of your videos. Please keep making videos almost about everything. God bless you so much.

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.

[@hannahdivic28]

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.

[@yellowindian5134]

[@emils-j.3586]

You, sir, are a gifted educator. Thunderous applause.

[@emils-j.3586]

It occurs to me you could basically do embryology as Pokémon-cards. "Embryoblast - Evolve!"

[@zsally5071]

I needed them so much last year 😥 Lucky you are new medical students 😍

[@alisoltaninezhad4613]

What a pity

[@ClaudiaBiguetti]

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

[@jhonyjosuecruzpelaez2227]

[@andrewsommerdc]

Love the awesome comment at 7:50 "... from this one cell we're actually going to make an entire human body"

[@estebanrriverarivera6046]

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.

[@DrTanishaa]

Are your sure about this? I have seen different thing in different sources so I'm not pretty sure about this. Can you confirm?

[@LoversGrief]

His videos are amazing, he has saved me on multiple occasions, but he should add a note on the video correcting that mistake. Still a great video nevertheless.
