The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

Journal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Activation of Bovine Oocytes Following Intracytoplasmic Sperm Injection (ICSI) [PDF]

, 2006
Intracytoplasmic sperm injection (ICSI), one of the methods of assisted fertilization, is the mechanical placement of a spermatozoon directly into the cytoplasm of an oocyte.

Lower developmental potential of rat zygotes produced by ooplasmic injection of testicular spermatozoa versus cauda epididymal spermatozoa

The Journal of Reproduction and Development
Intracytoplasmic sperm injection (ICSI) is clinically used to treat obstructive/nonobstructive azoospermia. This study compared the efficacy of ICSI with cauda epididymal and testicular sperm in Wistar (WI) and Brown-Norway (BN) rats.

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.

Micro-rubbing sperm immobilization promotes fertilization and oocyte utilization in intracytoplasmic sperm injection

Journal of Ovarian Research
Background Sperm immobilization is an important step in intracytoplasmic sperm injection (ICSI) as it is necessary for oocyte activation by the spermatozoa. Several techniques are available for sperm immobilization.

Microfluidic Intracytoplasmic Sperm Injection (MICSI): A Novel Platform for Sperm Isolation, Selection, and Injection Into Oocytes

Andrology, EarlyView.
ABSTRACT Background Infertility is a pressing global health concern, affecting one in six couples worldwide. The failure rate for assisted reproductive technologies (ART) cycles remains at approximately 78%, with limited improvements often attributed to a lack of technological innovation.

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Factors affecting the efficiency of foal production by intracytoplasmic sperm injection (ICSI) [PDF]

, 2016
Equine embryo production by intracytoplasmic sperm injection (ICSI) is currently effective enough to be used clinically. However, there are several factors that affect the efficiency of this procedure because, in addition to specialized equipment, skill ...
