Alterações no perfil esparmático e constituição histológica dos testículos de coelhos sob a influência do aumento transitório da temperatura testicular

This study was conducted to investigate the sperm profile of rabbits, evaluating concentration, motility vigor and incidence of sperm with changes in the compaction of genetic material (pathologies of the DNA protein complex), under normal conditions and under the influence of the transient increase in temperature testicular. Eight fertile rabbits were used evaluating the parameters of 3 ejaculates on alternate days and then the animals were subjected to an increase in testicular temperature for 3 days, collecting semen samples on Mondays, Wednesdays and Fridays for 38 days for analysis. . Every 5 days a rabbit underwent orchiectomy for histological evaluation of testicles and epididymis.
Avaliação andrológica em cães

The andrological examination of dogs is considered a great tool for owners and veterinarians involved in the commercial breeding of dogs, as it allows to properly select animals for breeding, providing data on the fertilizing capacity of each individual.
Estudo de embriões ovinos em laboratório a partir de doadoras juvenis da raça Santa Inês submetidas a estimulação ovariana

This study aimed to verify the superovulatory response of juvenile Santa Inês sheep and to evaluate the viability of oocytes obtained for in vitro production (IVP) of embryos. Eight females aged between 6 and 8 weeks were selected, distributed in 2 homogeneous groups of 04 animals. The females in Group 1 (G1) were submitted to exogenous ovarian stimulation and in Group 2 (G2) the females were aspirated free of hormonal treatment. From a total of 309 retrieved oocytes (G1 = 187 and G2 = 122), cleavage rates of 49.2% and 40.2% were obtained for G1 (n = 92) and G2 (n = 45) respectively, and 18.72% and 17.96% of viable embryo development in D7 (G1 = 35 and G2 = 19). Although the results suggest a better efficiency in the recovery of oocytes and cleavage rate in G1, the rates of obtaining viable embryos in D7 did not differ numerically between the two groups. Our results suggest that, although there was great variation in the amount of oocytes obtained and the production of embryos among animals, regardless of treatment, the production of embryos by in vitro fertilization (IVF) from juvenile females treated or not with exogenous hormones proved to be viable, even with good efficiency of the hormonal protocol used for females of the Santa Inês breed.
Monitoramento do ciclo estral de éguas por meio de ultrassonografia e biopsia uterina

The use of ultrasonography has facilitated the real-time characterization of ovarian structures and uterus, being able to follow the waves of follicular development and endometrial changes. However, it is not the only alternative to monitor the mitotic activity of the endometrium. The use of histology and immunohistochemistry, through uterine biopsy can be performed to monitor endometrial changes responsive to hormones, as well as to detect possible problems of subfertility.
