Brief Summary

During ovarian stimulation, all the follicles grow under the action of FSH, only the selected follicles and with the faster growth are taken. However during this stimulation, other smaller follicles are also recruited and sensitized, which may increase the selection of follicles available on the follicular wave following. In patients with weak reserve this potentiation has a great interest, and the sequence of 2 stimulations on the same cycle could make it possible to obtain a larger number of oocytes and embryos, thus giving a better chance of delivery than on 2 distinct cycles of stimulation. However, this is preliminary data that needs to be confirmed with a randomized controlled trial. In this population of poor prognosis, the use of FSH-associated LH activity may optimize the ovarian response to stimulation, particularly the combination containing placental HCG (Fertistartkit®) that obtaining a slightly higher number of oocytes than highly purified HMG (Menopur®).

Study Arms (2)

DUOSTIM

EXPERIMENTAL

(stim 1) flexible antagonist protocol with pre-treatment with estrogen (S1 between J1 and J8 under E2) and stimulation with Fertistartkit® 300 IU / d; triggering by rHCG (Ovitrelle®250μg) and puncture at 36h; oocyte freezing; (stim 2) resumption of stimulation only by Fertistratkit® 300 IU / day from the day after the puncture; introduction of Progestan® 7 days later to avoid menstruation during the second puncture; triggering with rHCG and second puncture at 36h associated with the devitrification of stim 1 oocytes, with sperm collection and embryonic vitrification. Transfer of frozen embryos to the subsequent cycle in the natural cycle (without HCG) and until the frozen embryos are exhausted.

Drug: DUOSTIM

Conventional stimuli

ACTIVE COMPARATOR

(stim 1) flexible antagonist protocol with pre-treatment with estrogen (S1 between J1 and J8 under E2) and stimulation with Fertistartkit® 300 IU / d; triggering by rHCG (Ovitrelle®250μg) and puncture at 36h; fresh embryonic transfer if satisfactory endometrial conditions with luteal phase support by vaginal micronized progesterone Progestan® 600 mg / d; otherwise embryonic freezing and transfer of frozen embryos to the subsequent cycle in the natural cycle until the frozen embryos are exhausted. (stim 2) ditto starting on the next cycle if possible or the next one. Hormonal Controls + Ultrasound During Stimulation: Blocking / S1 - S5 / S6 - S8 / S9 - SHCG / SHCG-1

Drug: Conventional stimuli

Interventions

2 consecutive stimulations by Fertistartkit® on the same cycle

Also known as: Same monthly cycle
DUOSTIM
