The first is that the CLs in IVF were all disturbed by the IVF needle for the length of egg opt upon-up. The CLs initiate as follicles containing eggs. At the retrieval, the needle is positioned in the follicle, the egg is purchased rid of; and the varying cells too can moreover be purchased rid of. The follicle is widely speakme fluid, nevertheless it moreover incorporates an inexperienced deal of cells that make up the follicle and surround the egg. These are is more often than not said as the granulosa cells; and those are the cells that convert to CL cells after ovulation. So if the needle removes a few of those cells, as is constantly the case, the CL would no longer work to boot, and fewer progesterone is produced.
The 2nd is to do with IVF therapy. In a natural and organic cycle, the hormone LH is secreted by the pituitary in small doses after ovulation, as this LH permits the CL to produce progesterone. However, for the length of an IVF cycle, easiest ladies are given Lupride, Gonapeptyl or Ovurelix to suppress a untimely LH surge at ovulation. In a natural and organic cycle or IUI, surges are notable, they trigger ovulation. In IVF, we are surfing to time the retrieval to the hour, merely so a surge on the inaccurate time ruins each house. So we offer drug cures to cease LH; nevertheless this strength LH is no longer doable to info the CL with progesterone production to boot.
