Sperm 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 کاملStimulation 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 کاملO-32: Effects of Intrauterine Injection of Recombinant Human Chorionic Gonadotropin before Embryo Transfer on Outcome of In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Randomized Clinical Trial
Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...
متن کاملHuman Chorionic Gonadotropin
A highly active preparation of human chorionic gonadotropin has been obtained by simple methods of column chromatography on diethylaminoethyl Sephadex and Sephadex G-100. The preparation appeared homogeneous by disc and immunoelectrophoresis, ultracentrifugation, and end group analysis. It assayed at 12,000 i.u. per mg by the rat prostrate gland and accessory sex organ method. The ~20,~ value w...
