SUMMARY

In triplet births, it is common to find only one corpus luteum due to the phenomenon of ovulation and fertilization dynamics. Typically, a single corpus luteum is formed from the ovulated egg, which can lead to multiple embryos if the egg splits or if multiple eggs are fertilized. This discussion highlights the distinction between fraternal and identical triplets, emphasizing the biological processes that govern multiple births.

PREREQUISITES
  • Understanding of human reproductive biology
  • Knowledge of ovulation and corpus luteum function
  • Familiarity with the concepts of fraternal and identical twins
  • Basic grasp of embryonic development
NEXT STEPS
  • Research the role of the corpus luteum in pregnancy
  • Study the differences between fraternal and identical triplets
  • Explore the hormonal changes during multiple pregnancies
  • Investigate the genetic factors influencing multiple births
USEFUL FOR

Students in biology or medicine, healthcare professionals, and anyone interested in reproductive health and the mechanisms behind multiple births.

Can someone elplain why only one corpus luteum may be found in the ovaries of a women who has given birth to triplets? Thanks!

Is this for homework? Based on the phrasing, I'm going to assume so for now. Whether you're talking about twins or triplets, what are the two different ways you can get multiples? Do you know the terms fraternal vs identical twins? What's the difference? Now apply the same concept to triplets.
 
As child, before I got my first X-ray, I used to fantasize that I might have a mirror image anatomy - my heart on the right, my appendix on the right. Why not? (Caveat: I'm not talking about sci-fi molecular-level mirroring. We're not talking starvation because I couldn't process certain proteins, etc.) I'm simpy tlakng about, when a normal zygote divides, it technically has two options which way to form. Oen would expcet a 50:50 split. But we all have our heart on the left and our...
