Sperm cryopreservation for impaired spermatogenesis

Reproduction and Fertility, 2023
Sperm cryopreservation for men with severely impaired spermatogenesis is one of the commonest reasons for short-term sperm storage, usually in advance of fertility treatment.

DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice. [PDF]

, 2020
Although thousands of genetically modified mouse strains have been cryopreserved by sperm freezing, the likelihood of cryorecovery success cannot be accurately predicted using conventional sperm parameters.

Mitochondria directly influence fertilisation outcome in the pig [PDF]

, 2006
The mitochondrion is explicitly involved in cytoplasmic regulation and is the cell's major generator of ATP. Our aim was to determine whether mitochondria alone could influence fertilisation outcome.

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Intracytoplasmic sperm injection (ICSI) [PDF]

Human Reproduction, 2000
IVF has become a well-established treatment for certain types of infertility, including long-standing infertility due to tubal disease, endometriosis, unexplained infertility or infertility involving a male factor. Soon it became clear that certain couples with severe male-factor infertility could not be helped by conventional IVF.

Neonatal outcome of early rescue ICSI and ICSI with ejaculated sperm [PDF]

Journal of Assisted Reproduction and Genetics, 2014
To evaluate the impact of early rescue ICSI on neonatal outcome.This retrospective study compared the neonatal outcome of early rescue ICSI and ICSI with ejaculated sperm, including 233 children who were conceived after early rescue ICSI and a control group of 906 children who were conceived after ICSI with ejaculated sperm, and all of the children had

Is ICSI Risky? [PDF]

Obstetrics and Gynecology International, 2013
As assisted reproductive technology (ART) methods become the mainstream of infertility treatment, it has become even more critical to reassess its safety. Following the results of a study published by the Robinson Institute in the New England Journal of Medicine, the risk of ART, especially intracytoplasmic sperm injection (ICSI), has never been so ...

Efficacy of Laser-Assisted Hatching on Pregnancy and Live-Birth Rates of Human Frozen-Thawed Embryos

Journal of Scientific Research in Science, 2023
Unexplained repeated in-vitro fertilization (IVF) failure is a major problem that faces both genders. The present study aims to estimate the influence of the laser-assisted hatching (LAH) technique on implantation, clinical pregnancy and live-birth rates
