PURPOSE: Prior studies suggest that pregnancy outcomes after autologous oocyte cryopreservation are similar to fresh in vitro fertilization (IVF) cycles. It is unknown whether there are differences in pregnancy and perinatal outcomes between cryopreserved oocytes and cryopreserved embryos. METHODS: This is a retrospective cohort study comparing pregnancy and perinatal outcomes between oocyte and embryo cryopreservation at a university-based fertility center. We included 42 patients and 68 embryo transfers in patients who underwent embryo transfer after elective oocyte preservation (frozen oocyte-derived embryo transfer (FOET)) from 2005 to 2015...

The current study investigates the utility of random-start ovarian stimulation in women desiring elective oocyte cryopreservation. Women in the study cohort underwent random-start ovarian stimulation, and were subdivided based on the phase of the menstrual cycle that ovarian stimulation began, i.e. early follicular, late follicular or luteal phase. Women undergoing conventional cycle day (CD) 2/3 ovarian stimulation start were controls. A total of 1302 women were included - 859 (66.0%) conventional CD 2/3, 342 (26...

Prolonged gonadotrophin-releasing hormone agonist (GnRHa) administration before IVF with fresh embryo transfer to patients with endometriosis or aberrant endometrial integrin expression (-integrin) improves outcomes but may suppress ovarian response and prevents elective cryopreservation of all embryos. This retrospective cohort pilot study evaluates freeze-all cycles with subsequent prolonged GnRHa before embryo transfer in these populations. Patients from 2010 to 2015 who met inclusion criteria and received a long-acting GnRHa every 28 days twice before FET were evaluated...

Importance: In vitro fertilization (IVF) has evolved dramatically in recent decades; however, clinical practices have been slow to adopt these advancements, particularly regarding final oocyte maturation and the timing of embryo transfer. Concerns still exist over the ability of gonadotropin-releasing hormone (GnRH) agonists and elective embryo cryopreservation to reduce the risk of ovarian hyperstimulation syndrome (OHSS) without compromising pregnancy outcomes. Objective: This review investigates IVF outcomes associated with GnRH-agonist triggering and elective embryo cryopreservation...

Improvements in oocyte cryopreservation has prompted wider acceptance of this technology leading to its use for several reasons. Notably, in addition to elective and medically driven reasons for oocyte cryostorage for fertility preservation, donor oocyte cryobanking is beginning to gain traction, potentially replacing fresh oocyte donation in assisted reproduction. Donor "egg banking," while not totally analogous to donor sperm banking, does provide strong benefits in terms of scheduling flexibility and improved clinical efficiencies, while providing a wider immediate inventory choice...

Elective embryo cryopreservation after using gonadotrophin-releasing hormone (GnRH) antagonist protocols and GnRH agonist triggering is becoming an increasingly important part of medically assisted reproduction. We designed a single-centre retrospective study to assess the cumulative probability of achieving a live birth through consecutive transfers of vitrified-warmed blastocysts after elective embryo cryopreservation in high-responding patients. Hence, 123 women identified to be at high risk for developing ovarian hyperstimulation syndrome were included...

STUDY QUESTION: Is there a difference in pregnancy rates between embryos transferred electively on Day 5 and Day 6, respectively? SUMMARY ANSWER: The chance of pregnancy is significantly reduced (odds ratio (OR): 0.34; 95% CI 0.22-0.52) if transfer is performed on Day 6 compared with Day 5. WHAT IS KNOWN ALREADY: Several studies report that Day 5 transfers have higher implantation rates (IRs) when compared with Day 6 transfers. These studies were based on non-elective Day 6 transfers, where transfers on Day 6 were performed with developmentally delayed embryos...

The freeze-all strategy has emerged as an alternative to fresh embryo transfer (ET) during in vitro fertilization (IVF) cycles. Although fresh ET is the norm during assisted reproductive therapies (ART), there are many concerns about the possible adverse effects of controlled ovarian stimulation (COS) over the endometrium. The supra-physiologic hormonal levels that occur during a conventional COS are associated with modifications in the peri-implantation endometrium, which may be related to a decrease in pregnancy rates and poorer obstetric and perinatal outcomes when comparing fresh to frozen-thawed embryo transfers...

STUDY QUESTION: Does the time from ovum pick-up (OPU) to frozen embryo transfer (FET) affect reproductive outcomes in a freeze-all strategy? SUMMARY ANSWER: Our study did not detect statistically significant differences between first and subsequent cycles, clinically relevant differences are not ruled out and further and larger studies are required. WHAT IS KNOWN ALREADY: Following controlled ovarian hyperstimulation (COH) delaying FET until the endometrium has returned to an optimal pre-stimulation state may have a significant emotional impact on patients, which adds to the stress and anxiety accompanying a standard IVF cycle...

Vinay Gunnala, Glenn Schattman
PURPOSE OF REVIEW: Oocyte cryopreservation is no longer experimental and one of its rapidly growing indications is elective fertility preservation. Currently there is no sufficient evidence to support its practice and therefore its place in IVF remains uncertain. RECENT FINDINGS: Vitrification has superior post-thaw survival and fertilization outcomes compared with oocytes that were frozen with the slow-freeze technique. Oocyte vitrification produces similar IVF outcomes compared with fresh oocytes and is not associated with further obstetrical or perinatal morbidity...

BACKGROUND: In vitro maturation (IVM) of immature oocytes is an important technology for selected clinical indications. We previously described a pregnant woman with a history of renal transplantation who underwent oocyte aspiration during cesarean section (CS) for fertility preservation and future surrogacy. CASE: A 27-year-old pregnant woman was diagnosed with neck rhabdomyosarcoma at 37 weeks' gestation. CS was performed with direct aspiration of small follicles from one ovary and oophorectomy of the other...
