Libido evaluation, serum testosterone and sperm quality goats treated with bioidentical testosterone transdermally
Keywords:
goat, exogenous hormone, time mountsAbstract
The objective of this study was to evaluate the effect of testosterone bioidentical by transdermal route of applicantion in goat scrotal, sexual behavior, quantitative and qualitative production of sperm, testosterone concentrations, FSH (Follicle Stimulating Hormone) and LH (luteinizing hormone) for the treatment of reproductive temporarily unable to play, since there is no data in the literature concerning association with hormone bioidêntico transdermal route of application in goats. We used four male goats (Saanen=03 and Anglo Nubian=01), with low libido and poor sperm quality, proven by andrological exam. Every week, over two months, it were taken and evalued sperm samples the scrotal circumference (SC) was mensure the bioidentical testosterone was applicated in the scrotal by transdermal route; blood samples were collected to determine serum testosterone, FSH and LH; beyond sexual behavior verification by testing libido. For purposes of data analysis used the statistical program SAS v.8 (2000). Serum testosterone showed significant differences depending on the treatment period, however, no significant difference was observed for FSH and LH between the different treatment periods. At the fresh and cooled sperm, the seminal parameters evaluated were not affected significantly throughout the experimental period. It can be concluded that the transdermal bioidentical testosterone application method in goats was effective, considering that it made the libido of treated animals more explicit, although despite the increase in serum testosterone levels, there was no interference in the seminal quality.
