Biology 133 lecture AY 2021- 2022

Hello Pie and Ella! I am Anne from group 4. Thank you for the informative presentation on spermiogenesis and spermiation. The images and figures you used were very helpful in understanding the presentation and visualizing the processes involved. I think it was interesting since we don’t usually talk about defects or disruptions in different stages, such as in spermiogenesis and spermiation, why they occur, and their effects on the succeeding processes.
Our group was just wondering if morphological defects such as abnormal sperm tail, head, and acrosome have any treatments and if it’s still possible to fertilize the egg.

Hello Ella and Pie! Thank you for your deliberate report and helpful report on Spermiogenesis and the possible morphological defects of the whole process. Our group (Castillo, Ching, R.M. Flores) was just wondering if those stated morphological defects could occur simultaneously on an individual, or if only one defect could manifest per individual?

Thank you for your clear presentation of your report. My questions are:
1. Please explain the mechanism by which the Sertoli cells which are supposed to support the spermatids during spermiogenesis eventually phagocytose them when they cannot leave the Sertoli cells in spermiation.
2. Please give examples of environmental factors that can affect spermiogenesis and spermiation.
Thank you.

Hi Pie and Ella! I'm Danica from Group 8 (Agtarap, Alanano, Avenido). Thank you for sharing more information about spermiogenesis and spermiation! The content and flow of information were concise and well presented so the material was easier to digest. The topic was also very interesting as it deviated away from just the usual normal process of spermiogenesis or spermiation. Our group would just like to ask if exposure to heavy metals such as lead or mercury affect spermiogenesis and spermiation?

Thank you and I hope you're enjoying your holidays!
