This study aimed to verify if the process of artificial insemination (AI) characterized here as animal immobilization, the passage of the semen applicator through the cervix, and deposition of the semen in the uterus, affected cows’ welfare. For this, 18 beef calved cows were selected and divi...
The objective of the present study was to obtain echobiometric values for the most important canine maternal-fetal tissues using high-definition ultrasonography (HDUS) trying to update the formulas for predicting gestational age. Twelve healthy bitches of brachycephalic breeds weighing 7-13kg and aged on...
This study describes a case of a dog with a lacerated penile tear treated with partial penectomy followed by successful semen collections for artificial insemination. A 1.5-year-old Jack Russel Terrier with normal libido, genital organs and semen, had a penile laceration after copulation. The dog underwe...
Recent studies have focused on the use of seminal plasma to increase sow fertility after classical intracervical artificial insemination (AI). The aim of the present study was to investigate the influence of seminal plasma infusion, prior to the application of conventional AI dose, on the fertility rate ...
This study investigated in vitro the efficacy of four different extenders (TES-TRIS and TRIS with LDL low-density lipoprotein at concentrations of 10 or 5%) on the longevity of buffalo sperm in the refrigeration process at 5ºC. Sperm motility was assessed every 24 hours up to 72 hours of incubation usin...

In the present study we aimed to test the best insemination dose for in vitro embryo production (IVEP) and to correlate sperm traits in bovine. In vitro matured oocytes were inseminated with three different sperm concentrations of the same bull: G1 (1*106), G2 (2*106) and G3 (4*106) sperm/mL. At 18 h pos...
Avaliaram-se diferentes momentos de aplicação da gonadotrofina coriônica equina (eCG) em protocolos de inseminação artificial em tempo fixo (IATF) para vacas de leite. Foram utilizadas 76 fêmeas, as quais receberam, no dia zero (D0) do protocolo, dispositivos intravaginais de progesterona, sendo es...
The objective of the study was to determine whether or not there is a correlation between thermoresistance tests (TT) after semen thawing and pregnancy rate (PR) after fixed-time artificial insemination (FTAI). Four different TT were performed on ten samples used for AI; a rapid test (RTT) (30min / 46°C...
A síndrome dos ovários policísticos (SOP) é responsável por cerca de 80% dos casos de infertilidade anovulatória. Não há na literatura evidências suficientes para a definição do tratamento ideal da infertilidade na SOP, mas repete-se que deve ser iniciado por mudanças no estilo de vida, e fre...

ABSTRACT BACKGROUND: The underlying cause of seasonal infertility in humans is unclear, but is likely to be multifactorial. OBJECTIVE: The aim of our study was to compare the pregnancy rates among infertile women who underwent induced ovulation and intrauterine insemination (IUI) with the season in...
