Assisted gamete treatment to pinpoint acquired meiotic maturity and overcome oocyte activation deficiency contributed by both gametes

F&S Reports, 2023
Objective: To treat couples with total fertilization failure (TFF) based on a combined oocyte- and sperm-related oocyte activation deficiency by optimizing oocyte response to chemical activation with calcium ionophore. Design: Case report.

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Bovine oocyte activation with bull or human sperm by conventional ICSI and Piezo-ICSI: Its relationship with PLCɀ activity

Open Veterinary Journal
Background: Intracytoplasmic sperm injection (ICSI) technique has low efficiency in cattle. This has mainly been attributed to the oocyte activation failure due to oocyte and/or sperm factors.

A first‐trimester mechanistic framework integrating three Physiopathologic biomarker domains for pre‐eclampsia classification

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To develop and internally validate a mechanistic, three‐domain framework for early classification and prediction of pre‐eclampsia (PE) using first‐trimester angiogenic, uteroplacental, and maternal vascular biomarkers. Methods In a prospective cohort of 1925 singleton pregnancies screened at 11 to 13.6 weeks, placental growth factor (

An efficiency comparison of different in vitro fertilization methods: IVF, ICSI, and PICSI for embryo development to the blastocyst stage from vitrified porcine immature oocytes

Porcine Health Management, 2018
Background Most studies carried out to evaluate recovery and development after porcine oocyte vitrification, reported better rates when cryopreserved in embryonic development stages or zygotes, but not in immature oocytes.

Metroplasty before IVF in women with a T‐shaped uterus: A clinical challenge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract A T‐shaped uterus is a uterine malformation, which can be either congenital or acquired, potentially impairing fertility and increasing the risk of miscarriage. Diagnosis primarily relies on three‐dimensional ultrasound and hysteroscopy. Hysteroscopic metroplasty is the standard surgical intervention aimed at restoring normal uterine anatomy ...
