Semen cryopreservation is a technique widely used in commercial and conservation fish farms. However, the success of the technique will depend on the diluent and cryoprotectant solutions added to the semen prior to the freezing procedure.

This study aims to investigate the effect of different cooling rates on the semen cryopreservation of curimba (Prochilodus lineatus). Nineteen ejaculates were obtained from adults males and cryopreser...
This study aims to describe seminal plasma characteristics, detect changes during and between two consecutive spawning seasons (SS), and compare plasma features between two important South American fi...
Seasonal variability in cattle fertility may be attributed to male reproduction, including the quality of semen produced by males and its usefulness after cryopreservation. The exact molecular mechani...
This study, for the first time in fish, compared the transcriptome of fresh and frozen-thawed sperm, and would help to better understand the effect of cryopreservation on fish sperm and then better pr...
Atrazine (ATZ) is a widely used herbicide that has the potential to contaminate the environment and cause deleterious effects on non-target organisms. Release systems for ATZ have been developed to mi...
To date, there are no published data on the role of melatonin supplementation or the appropriate dose for patients with multiple sclerosis. Because of the potential benefits of melatonin, ...
The primary focus of this five-year study will be to optimize the melatonin dosing regimen for synchronizing the body clocks of blind children to the 24-hour day.
Atypical antipsychotic medications, such as olanzapine, cause metabolic side effects, including weight gain, extra fat around the middle of the body, high blood sugar, and high cholesterol...
The aim of the study is to assess the effect of melatonin treatment in patients with osteopenia on BMD, muscle function, quality of life and calcium homeostasis.
Background: The treatment of inflammatory bowel diseases (IBD) is based mainly on 3 compounds: 1- 5 aminosalysilates . 2- immunomodulators (Azathioprines). 3- Biologic therapies (Inflixima...
A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
A family of G-protein-coupled receptors that are specific for and mediate the effects of MELATONIN. Activation of melatonin receptors has been associated with decreased intracellular CYCLIC AMP and increased hydrolysis of PHOSPHOINOSITIDES.
The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.
An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum. It is used principally to overcome low sperm count, low sperm motility, inability of sperm to penetrate the egg, or other conditions related to male infertility (INFERTILITY, MALE).
Interactive processes between the oocyte (OVUM) and the sperm (SPERMATOZOA) including sperm adhesion, ACROSOME REACTION, sperm penetration of the ZONA PELLUCIDA, and events leading to FERTILIZATION.
