Sperm cryopreservation protocol for micro-TESE-retrieved sperm [PDF]

open access: yesAsian Journal of Andrology
Azoospermia is characterized by the absence of sperm in the ejaculate and is categorized into obstructive azoospermia (OA) and nonobstructive azoospermia (NOA).

Cryopreservation Techniques for Ram Sperm

open access: yesVeterinary Medicine International, 2022
Germplasm storage and transportation in artificial insemination (AI) and other advanced technologies are facilitated by cryopreservation. In reproduction, the cryopreservation of sperm allows it to be transported across vast distances and used even after

Sperm cryopreservation for impaired spermatogenesis. [PDF]

open access: yesReprod Fertil, 2022
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. Cryopreservation is generally very effective, although not all spermatozoa survive the process of freezing and thawing.

Ferroptosis emerges as the predominant form of regulated cell death in goat sperm cryopreservation [PDF]

open access: yesJournal of Animal Science and Biotechnology
Background Freezing-induced sperm damage, often associated with oxidative stress, can result in regulated cell death. Given that oxidative stress can trigger various forms of regulated cell death, the prevailing form during sperm cryopreservation remains

Restoring Sperm Quality Post-Cryopreservation Using Mitochondrial-Targeted Compounds

open access: yesAntioxidants, 2022
While critical for male fertility preservation, cryopreservation damage reduces sperm quality and fertilization potential. This study investigated whether the addition of mitochondrial-targeted, antioxidant compounds, also known as Mitochondrial ...

The impact of adding melatonin and other antioxidants on post-thaw human sperm quality during cryopreservation

open access: yesMedical Journal of Babylon, 2023
Sperm cryopreservation is the process of storing sperm for an extended period of time in order to maintain male fertility. Cryopreservation involves exposing germ cells to substances that prevent freezing, cooling them to below-freezing temperatures ...

Step by step optimization of a sperm cryopreservation protocol for spotted wolffish (Anarhichas minor Olafsen, 1772) [PDF]

open access: yes, 2020
Spotted wolffish Anarhichas minor reproduction in captivity is dependent on in vitro fertilization. However, low sperm volume with relatively low cell concentration and the lack of gametes synchronization (simultaneous availability of mature eggs and ...

Cryopreservation of single-sperm: where are we today?

open access: yesReproductive Biology and Endocrinology, 2020
Background Patients with severe oligospermia and nonobstructive azoospermia have very limited numbers of viable sperm in their epididymal and testicular samples. Thus, cryopreservation of their sperm is performed to avoid repeated sperm retrievals and to

Update on techniques for cryopreservation of human spermatozoa

open access: yesAsian Journal of Andrology, 2022
In the 1960s, sperm cryopreservation was developed as a method to preserve fertility. Currently, techniques for the cryopreservation of human spermatozoa have been widely used in assisted reproduction. However, although sperm cryobiology has made notable
