1. Effect of hCG application at different moments of the estrous cycle on corpus luteum and uterine vascularization and serum progesterone concentration in mares
Abstract Establishment of pregnancy after embryo transfer is the ultimate goal of an embryo transfer program and increasing pregnancy rates and reducing pregnancy loss are mandatory. The utilization of treatments to improve conception rates in recipient mares has been the focus of several research groups over the last years and the results are controversial.

3. Pregnancy of Unknown Location: The Value of Frozen Section Analysis and Its Relation to Beta-hCG Levels and Endometrial Thickness
Abstract Objective Frozen section examination is a rapid method for identifying products of conception in endometrial curetting, yet its accuracy is inconclusive. The purposes of this study is to determine the accuracy of frozen section analysis of endometrial curetting in pregnancies of unknown location, and to verify the relation of β-human chorionic go

4. Induction of ovulation in quarter horse mares through the use of deslorelin acetate and human chorionic gonadotrophin (hCG)
The aim this study was to compare two protocols of induction for ovulation by desloreline acetate and hCG in Quarter Horse mares. The choice of the animals was based on the observations by the estrus, by rectal palpation of the ovaries and by ultrassonography of the follicular dynamics. After estrus detection and follicle control, the measurement of the foll

5. Purificação da gonadotrofina coriônica eqüina, do plasma sanguíneo de éguas prenhes, por cromatografia de afinidade / Equine chorionic gonadotrophin purification, from pregnant mare plasma, by affinity chromatography
A Gonadotrofina Coriônica Eqüina (eCG) é produzida pela égua prenhe e tem ação folículo estimulante e luteinizante em animais domésticos não eqüídeos. Um pool formado por plasma de 4 éguas prenhes, com média de 69 dias de gestação, foi purificado em coluna cromatográfica com resina de afinidade Blue Sepharose FF (BS). As frações que adsorve

6. Efeitos da bromocriptina na prevenção da síndrome do hiperestímulo ovariano precoce em mulheres de alto risco submetidas a fertilização in vitro / Effects of bromocriptine in the prevention of early ovarian hyperstimulation syndrome in high risk women submitted to in vitro fertilization
Objective: To evaluate the effect of bromocriptine for the prevention of either early moderate or severe ovarian hyperstimulation syndrome (OHSS) in high risk women submitted to in vitro fertilization. Patients and Methods: A double-blind, prospective, randomized study was carried out between February 2006 and November 2007 at the Human Reproduction Center,

7. Structural analysis of gubernaculum testis in cryptorchid patients submitted to treatment with human chorionic gonadotrophin
OBJECTIVES: To make a histological and stereological analysis of gubernaculum testis elastic system fibers, collagen and striated muscle cells in patients with cryptorchidism treated with human chorionic gonadotrophin (hCG). MATERIALS AND METHODS: Gubernacula tissue samples were obtained from 12 patients with cryptorchidism. Patients' ages ranged from 1 to 3

8. Stereological and morphometric analysis of collagen and seminiferous tubules in testes of patients with cryptorchidism submitted or not to treatment with human chorionic gonadotrophin
OBJECTIVES: Quantify the distribution of collagen and analyze the seminiferous tubules diameter in the testis of patients with cryptorchidism, to verify if the previous use of human chorionic gonadotrophin (hCG) affects these structures. MATERIALS AND METHODS: Samples of parenchymal tissue of cryptorchid testis obtained during peroperative biopsies were coll

9. Efeito da dose e do momento da administração de gonadotrofina coriônica eqüina (eCG) no protocolo de sincronização da ovulação para transferência de embriões em tempo fixo / Effect of dose and moment of equine chorionic gonadotrophin (eCG) administration in the synchronization of ovulation protocol for fixed-time embryo transfer
The aim of this study was to compare the effects of different doses of eCG administrated at two moments in a fixed-time embryo transfer protocol. On day 0, the heifers received a progesterone releasing vaginal insert (PRVI) and an injection of 2.0 mg Estradiol Benzoate (EB) associated with 50 mg progesterone (P4) i.m. The animals were randomly assigned to si

11. Synchronization of ovulation in crossbred dairy heifers using gonadotrophin-releasing hormone agonist, prostaglandin F2a and human chorionic gonadotrophin or estradiol benzoate
Girolando (Gir x Holstein) is a very common dairy breed in Brazil because it combines the rusticity of Gir (Bos indicus) with the high milk yield of Holstein (Bos taurus). The ovarian follicular dynamics and hormonal treatments for synchronization of ovulation and timed artificial insemination were studied in Girolando heifers. The injection of a gonadotroph

12. Parâmetros utilizados na avaliação do sêmen congelado ovino para inseminação laparoscópica
Com a finalidade de verificar o valor de alguns atributos para avaliação da qualidade do sêmen congelado, através da prenhez, duzentas e noventa e sete ovelhas da raça Corriedale foram inseminadas, intra-uterinamente, por laparoscopia. Utilizou-se cio sincronizado, com pessários vaginais contendo 50 mg de MAP (acetato de medroxiprogesterona), por 12 di
