Stimulation of Spermiation by Human Chorionic Gonadotropin and Carp Pituitary Extract in Grass Puffer, Takifugu niphobles
Spermiation was stimulated in the mature grass puffer, Takifugu niphobles, with an injection of human chorionic gonadotropin (HCG) or carp pituitary extract (CPE). Spermatocrit and sperm density were reduced, but milt production was increased in both the HCG and CPE treatment groups relative to those in the control group (P <0.05). These results should be useful for increasing the fertilization...
متن کاملSperm Production and Cryopreservation in Muskellunge after Carp Pituitary Extract and Human Chorionic Gonadotropin Injection
— We investigated the effects of carp pituitary extract (CPE) and human chorionic gonadotropin (hCG) on the sperm production in muskellunge Esox masquinongy. Total volumes of milt collected from fish (mean weight, 4.8 ± 1.5 kg) injected with CPE, hCG, or the saline control were 5.36 ± 3.75 mL, 3.1 ± 1.52 mL, and 3.89 ±2.16 mL, respectively. Sperm concentration, protein and mineral concentration...
متن کاملIdentification of the sex-determining locus in grass puffer (Takifugu niphobles) provides evidence for sex-chromosome turnover in a subset of Takifugu species
There is increasing evidence for frequent turnover in sex chromosomes in vertebrates. Yet experimental systems suitable for tracing the detailed process of turnover are rare. In theory, homologous turnover is possible if the new sex-determining locus is established on the existing sex-chromosome. However, there is no empirical evidence for such an event. The genus Takifugu includes fugu (Takifu...
متن کاملQuantification of Human Chorionic Gonadotropin by Bovine Serum Albumin Nanoparticles
Background and Aims: Some nanoparticles can be used in immunoassays to increase sensitivity. This study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (BSA NPs). Materials and methods: At first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. Then the concentration of β-subunit of human chorionic gonadotropin ...
