Oocyte Donation [PDF]

, 2017
The use of donor oocytes has expanded the scope of assisted reproductive technology (ART) for women with poor oocyte quantity and quality. In vitro fertilisation with oocyte donation (IVF-OD) is considered to give better implantation, pregnancy, and ...

A Higher Estradiol Rise After Dual Trigger in Progestin-Primed Ovarian Stimulation Is Associated With a Lower Oocyte and Mature Oocyte Yield in Normal Responders

Frontiers in Endocrinology, 2019
Background: Prior studies have shown that patients with a >10% estradiol (E2) rise after trigger had more oocytes retrieved than plateauing or decreasing E2 responders.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Oocyte donation pregnancies-non-disclosure of oocyte recipient status to obstetric care providers and perinatal outcomes [PDF]

, 2017
Background: Oocyte donation pregnancies-non-disclosure of oocyte recipient (OR) status to obstetric care providers and perinatal outcomes. Many studies report a higher rate of pregnancy-induced hypertension (PIH) and severe pre-eclampsia (PET) in OR ...

Role of arachidonic acid cascade in Rhinella arenarum oocyte maturation [PDF]

, 2015
There are no studies that document the production of prostaglandins (PGs) or their role in Rhinella arenarum oocyte maturation. In this study, we analysed the effect of arachidonic acid (AA) andprostaglandins (PGs) on maturation, activation and ...

At Home Detection of Ovarian Health Biomarker in Menstruation Blood

Advanced Materials Technologies, EarlyView.
A lateral flow assay enables the detection of anti‐Müllerian hormone directly in unprocessed menstrual blood using silica‐gold nanoshells and smartphone‐assisted machine learning analysis. The platform supports decentralized, user‐operated testing in wearable and dipstick formats, highlighting the potential of menstrual blood as a non‐invasive matrix ...

Oocyte In Vitro Maturation with Crude Sperm Extract Protein of Bull's Spermatozoa

Journal of Experimental Life Science, 2016
Oocyte In vitro maturation (IVM) is one of the important parts for in vitro fertilization (IVF). The success of oocyte maturation is influenced by the composit ion and the quality of IVM medium.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Ovarian aging: energy metabolism of oocytes

Journal of Ovarian Research
In women who are getting older, the quantity and quality of their follicles or oocytes and decline. This is characterized by decreased ovarian reserve function (DOR), fewer remaining oocytes, and lower quality oocytes.
