Corpus Luteum - progesterone

Post by charl_6 » Tue Dec 01, 2015 6:02 am

I have a simple question about Corpus Luteum (CL) in the case of IVF.

Is there a functional CL after oocyte extraction or is there several CL if the Dr extracts several oocytes? I can not find any scientific material regarding the development/function of Corpus Luteum after oocyte extraction during IVF. Because the follicle is 'damaged' when the vacuum-needle is inserted and the oocytes (eggs) are sucked out. Can this damaged follicle turn into a functional Corpus Luteum?

BEST!

Corpra lutea are formed but do not function adequately and that's why supplemental estrogen and progesterone are given following egg retrieval in fresh cycles.

Hi!

Thanks for Your answer.
I can not find any specific time/duration of treatment with progesterone. I have searched around the scientific material that could be found especially Pubmed and Cochrane and found some reviews and some newer articles. I could not find any answer according treatment time. Some says max until positive urine hCG test, some says until the placenta takes over the production of progesterone.

What is Your recommendation if the reason to the IVF today is unclear and probably is due to LPD (luthenal phase deficiency) of some kind? Otherwise 100% healthy woman.

Thank you!

The duration of treatment with estrogen and progesterone varies with weaning and ultimately discontinuation based on rising blood levels.
