Sharing Session: What is Follicles??

What is Follicle?

It's the sac (kantung) that carries your egg..the egg is developed inside this sac and bila LH is induced by injection or surge naturally, the sac will rupture to release egg and ready to be fertilized (yeay) before turning into zygote..apakah ittew zygote??..ermm is like our baby before turning to be embryo..kira zygote ni  is like sel sel yang tengah membahagi..

Most sac has 1 egg each..when the sac grows meaning that the egg is grooming and growing inside..its like nested programming lah *If you all amik IT..hehe

Back to the topic..Most follicles have one egg in them, they are called "dominant" that means they are larger and will be the ones that will cause the LH surge which indicate Ovulation is about to occur. *Ini lah yang Brenda nak cucuk kat ER malam ni...pukul 10 malam..untuk memecahkan follie yang mengandung telor masak ranum..bila cucuk malam ni..most probably brenda akan ovulate after 36 hours..

Ikut secara semulajadi or naturally, the LH surge occurs when one or more follicles REACH  the peak size and set off a chemical reaction. 

Only follicles that are a certain size (at least 18mm) will contain eggs big enough to be mature. 

If you have other smaller follicles, those eggs might also will be released when the LH surge occurs, but the eggs will be immature and unable to be fertilized.*Ingat, hanya telor yang matang sahaja akan di fertilized selepas bergabung dengan sperm..

Bad egg + Great Sperm = No good *pouting lips

Great egg + Bad Sperm = Also not good *pouting even more!

Susah betul ya...macam matematik!

.......

Great egg (Matang) + Good/Great Sperm = GOOOOODDDD!!

NICEEEEEEE...eheks

Normal average follicle for Mature Egg?

It depends on the treatment you are having (if any). With injectibles (treatment yang mahal ni..), they like to see follies of around 17mm (it will vary from clinic to clinic) with clomid, they prefer 20-22mm. 

The docs  say that the follies grow around 2mm per day....

But you cannot by any means rely on this. Ada cycle went according to text book..one of my friend ada yang didn't grow for 3 day! and suddenly shot up terus ke 5mm over 1 night..*lain orang lain gaya...hehe

Fyi, minimum 16mm of follicle is good to go for Pregnyl or Purbegen shot. Why? The egg will keep on growing inside the sac eventho we had our trigger shot. Meaning that, after our injection, our eggs still got another 36 hours to grow bigger. and remember it can reach 1mm-2mm per day..For instance:

My Right Ovary (3 Follicles)

Before Trigger ?                                                                   Size after?  

#16mm                                                                                   18mm or 19mm                                                                       

#15mm      -------->  TRIGGER ---->RUPTURE  ---->     17mm or 18mm

#13mm                                    ( 36 Hours )                           15mm or17mm 

Left Ovary (Follicle)

Before Trigger:                                                                 Size after :                                                                                                                                                     

21      -------->     TRIGGER ---->RUPTURE    ---->     23mm or 25mm

                                      ( 36 Hours  )                  

Yellow circle is ovary...arrow with big circle is dominant folli..
which contains matured eggs...Credit to Google.. :) 

Is Follicle has maximum size?

According to various of information, yes they do have maximum size..I found this info in this study on IVF

".the maximum preovulatory diameter can range from 19 to 24 mm. However, the largest diameter in these cases estimated by Fossum et al. ranged between 22 and 31 mm."
