Objective: To present the first genetically proven identity of quintuplets in an IVF treatment cycle after transferring only two embryos.
Design: Case report.
Setting: IVF unit and obstetrics department of university-affiliated general hospital.
Patient(s): Twenty-five-year-old patient undergoing IVF treatment for unexplained infertility.
Intervention(s): In vitro fertilization with intracytoplasmic sperm injection performed on 50% of oocytes, resulting in successful production of nine early-cleavage embryos. Transfer of two embryos on day 3 and freezing of the remaining embryos.
Main Outcome Measure(s): Development of five separate embryonic sacs. Fetal reduction of three embryos at 12 weeks of gestation.
Result(s): Successful completion of the twin pregnancy and full genetic analysis of the three embryos and the twins that were born at term.
Conclusion(s): Despite transferring only two embryos, superfecundation occurred, resulting in five embryos. Genetic analysis can be used to determine paternity and identity of all the embryos.

Artificial oocyte activation (AOA) with Ca2+ ionophores is an experimental procedure that benefits patients who fail to obtain fertilized eggs. However, the impact of non-physiological Ca2+ increases on cellular events involved in egg-embryo transition and early development remains poorly understood. Using the mouse model, this study compares common Ca2+ ionophore protocols applied in clinical practice - one or two exposures to A23187 or a single exposure to ionomycin - focusing on embryonic development and cellular events associated with egg activation.

Oocyte quality is crucial for determining the subsequent embryo developmental capacity and reproductive outcomes. However, aging is detrimental to oocyte quality. Previous studies have demonstrated that soy isoflavones have positive effects on the reproductive performance of female pigs.

Aphids exhibit a unique reproductive strategy known as pseudoplacental viviparity, in which embryos develop internally and are thought to receive nutrients such as sugars and amino acids directly from the maternal hemolymph through an ovariole sheath, bypassing the need for traditional yolk storage. This system enables viviparous aphids to adapt to diverse and potentially stressful environments by transmitting maternal environmental cues that influence transgenerational plasticity. However, the mechanisms underlying this nutrient-mediated plasticity are poorly understood.
