Microfluidic Systems for Isolation of Spermatozoa from Testicular Specimens of Non-Obstructive Azoospermic Men: Does/Can It Improve Sperm Yield?

open access: yes, 2021
Intracytoplasmic sperm injection (ICSI) has allowed reproduction options through assisted reproductive technologies (ARTs) for men with no spermatozoa within the ejaculate (azoospermia).

Intracytoplasmic sperm injection in Scandinavia [PDF]

open access: yesHuman Reproduction, 1996
Several Scandinavian clinics are now practising intracytoplasmic sperm injection (ICSI), and our data largely resemble that published from the Brussels group (Van Steirteghem et ai., 1993). In recent meetings, Scandinavian workers have come to some mutual decisions: (i) not more than two embryos will be replaced; (ii) recombinant follicle stimulating ...

Intracytoplasmic sperm injection using cryopreserved, fixed, and freeze-dried sperm in eggs of Nile tilapia

open access: yes, 2005
Gamete preservation techniques are essential in animal husbandry as well as in assisted reproduction for humans. In this research we attempted to use 3 different sperm preservation techniques in combination with newly developed techniques for ...

Sperm Decondensation and Male Pronuclear Formation in Bovine Intracytoplasmic Sperm Injection

open access: yes, 2020
This study assessed the effects both DTT and progesterone have on bovine spermatozoa to induce decondensation or the acrosome reaction in order to facilitate male pronuclear formation after ICSI.

Intracytoplasmic sperm injection (ICSI) in fishes

open access: yes, 2002
Sperm from zebrafish, Danio rerio, and Nile tilapia, Oreochromis niloticus, were microinjected directly into egg cytoplasm to evaluate the potential for developing a novel method of fertilization. In zebrafish, the sperm of two lines (wild-type and gold,

173 COMPARISON OF FERTILIZATION RATES OF EQUINE OOCYTES USING IN VITRO FERTILIZATION, PERIVITELLINE AND INTRACYTOPLASMIC SPERM INJECTIONS

open access: yes, 2012
In vitro fertilization in horses has had limited and inconsistent success for oocytes matured in vivo or in vitro. However, oocytes transferred to the oviducts of inseminated recipient mares are consistently fertilized and result in normal embryo ...

Longitudinal surface measurements of human blastocysts show that the dynamics of blastocoel expansion are associated with fertilization method and ongoing pregnancy

open access: yesReproductive Biology and Endocrinology, 2022
Background Despite all research efforts during this era of novel time-lapse morphokinetic parameters, a morphological grading system is still routinely being used for embryo selection at the blastocyst stage.

The KIF6‐RBP Complex Orchestrates mRNA Transport Required for Sperm Flagellar Assembly

open access: yesAdvanced Science, EarlyView.
Two homozygous deleterious KIF6 variants are identified in unrelated men with impaired sperm motility. Mouse models and multi‐omics analyses reveal that KIF6 cooperates with the RNA‐binding proteins FMRP and FXR1 to deliver mRNAs essential for sperm flagellar assembly, linking disrupted mRNA transport to reduced abundance of key structural and ...
