“…The percentage of pregnancies per cycle is significantly higher for embryos originating from highly vascular follicles compared to those from medium to poorly vascular follicles (Borini et al 2004). In the present study, we observed that ovarian artery perfusion increases during ovulation.…”

Pesq. Vet. Bras. 33(9):1144-1150, setembro 2013 1144 RESUMO.-[Ultrassonografia Doppler ovariana e ute-rina em cadelas.] Este trabalho teve como objetivo des-crever as características ultrassonográficas uterinas e ova-rianas, e dopplervelocimétricas das suas artérias nos dias periovulatórios em cadelas. Quinze ciclos estrais em 10 ani-mais foram avaliados. As características ultrassonográficas, índices de resistência (IR) e índices de pulsatilidade (IP) do útero e dos ovários em cada animal foram registrados 5 dias antes e depois da ovulação (D0). Os dados foram anali-sados estatisticamente e os resultados foram expressos em média ± erro padrão da média (P<0,05). Como resultados as características ultrassonográficas uterinas foram seme-lhantes em todos os ciclos e dias avaliados, tendo o corpo uterino um diâmetro médio de 0,85±0,02cm. Foi observado um aumento no volume dos ovários e nos diâmetros dos folículos, tendo os ovários um volume de 0,64±0,06cm 3 , e a cavidade dos folículos um diâmetro de 0,46±0,01cm no dia da ovulação. Após a ovulação, foi observado colapso dos folículos somente em alguns ciclos. A perfusão sanguínea uterina diminuiu dois dias antes da ovulação e permane-ceu inalterada até a ovulação. Após a ovulação, houve um aumento gradual na perfusão das artérias uterinas e ova-rianas, direcionando o fluxo de sangue para os ovários e This paper aims to describe the uterine and ovarian ultrasonographic characteristics and Doppler velocimetric features of their arteries in bitches during the periovulatory period. Fifteen estrous cycles in 10 animals were evaluated. The ultrasonographic characteristics , resistance indices (RI) and pulsatility indices (PI) of the uterus and ovaries in each animal were recorded 5 days before and after ovulation (D0). The data were statistically analyzed, and the results were expressed as the mean ± standard error of mean (P<0.05). In results the ultrasonographic features of the uterus were the same on all of the cycles and evaluated days. The uterus had an average diameter of 0.85±0.02cm. An increase in the volume of the ovaries and the diameter of the ovarian follicles were measured. Ovaries had a volume of 0.64±0.06cm 3 , and the follicles cavities had a diameter of 0.46 ± 0.01 cm on the day of ovulation. After ovulation, it was observed that some follicles not collapse in some cycles. Two days prior to ovulation, the uterine blood perfusion decreased. This decrease remained unchanged until ovulation. Following ovulation, we measured a gradual increase in the uterine perfusion and in the ovarian artery. This artery directed blood flow to the ovaries and increased the intra-ovarian perfusion on the day after ovulation. In conclusion, specific features are observed in the uterus and ovarian ultrasound image and Doppler values of their arteries presented on the periovulatory days and when associated allow to estimate more accurately the date of ovulation.

“…Vascularization of the female reproductive system seems to play an important role in oocyte developmental competence and uterine receptivity 14. The first approach to the study of genital vascularity was the use of the Doppler technique, which employed pulsed Doppler, which had evident limitations in the study of microvascularity 14. In 1994, a new mode of Doppler ultrasonography14 was introduced which improved visualization of small vessels (Fig.…”

Evaluation of morphological characteristics, to date, has been the most widely accepted method for the selection of embryos with higher developmental ability and optimization of the outcome of in vitro fertilization (IVF). Improvement in clinical results has also been pursued through attempts to generate embryos of high quality or to identify more reliable selection criteria. This work evaluates the possibility of improving embryo quality and subsequent IVF outcome in situations in which creation of supernumerary embryos is not allowed. Optimization of gamete selection and conditions of insemination, such as hormonal therapy to improve sperm quality of patients undergoing intracytoplasmic sperm injection treatment, use of power Doppler image for follicle selection, short coincubation of gametes during insemination, and use of a polscope for spindle detection, is described.
