Cryopreservation of Rooster Sperm
Successful cryopreservation of sperm requires: 1) selection of proper diluent; 2) selection of the best cryoprotectant; 3) determination of freezing and thawing rates for optimum retention of fertilization potential; and 4) removal of any materials deleterious to fertility (e.g., glycerol) before insemination.

Cryopreservation Effects on Ram Sperm Ultrastructure [PDF]
Cryoprotectants are known to have protective effects against cryodamage to spermatozoa. In this study, the cryoprotective effects of two cryoprotectants (glycerol, ethylene glycol) and cryoprotectants/trehalose combinations on frozen-thawed ram spermatozoa were investigated at the ultrastructural level. For this purpose, ejaculates

Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review
ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.

Computerized Sperm Motility and Application of Sperm Cryopreservation [PDF]
An objective method for measuring sperm motion characteristics was developed on an Intellect 100 Quantel Image Analysis System suitable for various image cytometric applications. It provided overall analysis of percent motility (% MS) as well as individual and mean measurements of motion characteristics, including vigor characteristics such as ...

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.

Sperm cryopreservation: effects on chromatin structure. [PDF]
Cryopreservation is a technique that can keep sperm alive indefinitely, enabling the conservation of male fertility. It involves the cooling of semen samples and their storage at -196°C in liquid nitrogen.

Optimization of sterlet sperm concentration for cryopreservation [PDF]
One of the critical points in low temperature storage is the expense of storage capacities. Moreover, sperm concentration in a sample is not only a parameter for effective use of a cryobanks but also a parameter affecting cryopreservation outcomes ...

Long-Term Experience of Sperm Cryopreservation in Cancer Patients in a Single Fertility Center
Purpose: Sperm cryopreservation before cancer treatment is the most effective method to preserve the fertility of male pa-tients. We present our 21 years experience with sperm cryopreservation for cancer patients, including an examination of se-men ...
