crinone kiek per daug jis pasisalins, iškris perteklius
Jeigu vadovaujantis logika, kad perteklius iškrenta, ar galima galvoti, kad jo trūksta, jeigu niekada neiškrenta nė gabaliukas? Kad viską įsisavina ir dar gal pritrūksta?
Susumavus du dalykus: kad man nekrito crinonas ir kad mmm atėjo 2 dienom per anksti, ar galima įtarti, kad man buvo mažai arba kad neįsisavino prg?
Kitas dalykas, pasikartosiu, tačiau, kiek suprantu, su natūraliu prg sumuoti nelabai patartina, nes per IVF ištraukia folikulus su visu skysčiu ir nelieka geltonkūnio, nu kažkas tokio
tam ir dedam crinoną, nes natūraliai po ivf nesigamina, tik vėliau pradeda gamintis.

Normally when we ovulate, the egg bursts out of the follicle. The empty follicle is then called the corpus luteum and its job is to produce progesterone. Progesterone prepares the uterine lining for implantation and is necessary to sustain a healthy pregnancy. If you are not pregnant, the the corpus luteum only lasts for about 12-14 days. When progesterone levels drop, this signals to the body to shed the lining, which is why you have a period.
But, if an egg is fertilized and implants, the HCG tells the corpus luteum to keep producing progesterone and the corpus luteum lasts for about ten weeks after ovulation and produces progesterone. After ten weeks the placenta takes over the progesterone production.
IVF is a little different for two reason. The first is that the follicles and the corpus luteums were disturbed by the IVF needle. At the retrieval, the needle is placed into the follicle and the egg is removed, but other cells can also be removed. The follicle is mostly fluid, but it also contains tons of cells that make up the follicle and surround the egg. These cells (called granuslosa cells) are the cells that convert to progesterone after ovulation. So, if the needle removes some of these cells, which will most likely happen, the corpus luteum may not work as well and less progesterone would be produced.
The second reason is because of the IVF meds. The corpus luteum needs leutinizing hormone (LH) hormone to help it carry out its function. Normally our bodies produce LH and the big LH surge is what causes us to ovulate (and is the hormone that OPKs measure). In IVF and other assisted cycles, HCG (for example ovidrel) is used in place of the LH. After ovulation, LH is produced in smaller amounts to get the follicle ready to produce progesterone. I believe that LH is secreted throughout the luteal phase to keep the CL making progesterone. If there is a problem with LH production there will be a problem with progesterone production and therefore there will be a problem with the pregnancy. Most women who do IVF are given a medication that causes a problem for LH production (such as Lupron or Antagon). The point is to stop LH production because a premature LH surge can ruin the cycle. If you ovulated too early, the RE would obviously not be able to retrieve the eggs in time.
