I need to do a second egg retrieval cycle. Does there need to be any downtime between cycles?
Back to back cycles of ovarian stimulation (2 weeks from first retrieval to next stimulation start) shorten treatment duration with similar treatment outcomes regardless of ovarian reserve.
BACK TO BACK OVARIAN STIMULATION SHORTENS TREATMENT DURATION WITHOUT COMPROMISING OUTCOMES

How long can I store my eggs?
Over a 9 year study period, the duration of oocyte cryopreservation did not affect the number of blastocysts or chromosomally normal blastocysts obtained after oocyte thaw.
Duration of cryostorage is not associated with rates of thaw survival, fertilization, blastulation and ploidy, or pregnancy outcomes of vitrified human oocytes

My previous IVF cycle didn’t go as well as I hoped. Is there anything else we can try?
Calcium ionophore, frequently referred to as calcium activation, can be applied in patients with a history of poor embryo development to increase the number of embryos developing to the blastocyst stage. For many patients who otherwise have a poor prognosis with IVF, that means more viable embryos to work with, and better odds of a healthy pregnancy.
