Cryopreservation of Pike Perch Sperm in Hatchery Conditions [PDF]
Experiments were carried out on pike perch (Sander lucioperca L.) to find a method for stripping sperm without contamination by urine, to determine sperm concentration, and to fertilize large batches of eggs with cryopreserved sperm.

Advances in Cryopreservation of Bull Sperm [PDF]
Cryopreservation of semen and artificial insemination have an important, positive impact on cattle production, and product quality. Through the use of cryopreserved semen and artificial insemination, sperm from the best breeding bulls can be used to inseminate thousands of cows around the world.

Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

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

As the demand for assisted reproductive techniques in humans increases, so does the demand for the oocytes and sperm that are essential for these techniques. Human sperm banks play a key role in assisted human reproduction, as a reservoir of sperm from the semen of donors and as an option for genetic preservation for some patients.

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.
