The goal of this study was to determine the effects of the length of the preovulatory phase on
genital blood flow and mRNA expression of endometrial hormone receptors in cattle (Bos …

The aim of this study was to examine the hypothesis that follicular and uterine perfusion as
well as endometrial gene expression during the ovulatory period differs after induction of …

Colour Doppler ultrasonography was used to compare the ability of preovulatory follicle
(POF) blood flow and its dimensions to predict the size, blood flow and progesterone …

Haemodynamic changes are involved in the cyclic remodelling of ovarian tissue that occurs
during final follicular growth, ovulation and new corpus luteum development. The aim of this …

Simple Summary Blood supply of female reproductive organs plays an important role in
reproductive performance in cattle. Ovarian and uterine arterial indices (vascularised area) …

In beef cattle, the ability to conceive has been associated positively with size of the
preovulatory follicle (POF). Proestrus estradiol and subsequent progesterone concentrations …

Two experiments evaluated the influence of follicular wave at artificial insemination (AI) on
fertility of dairy cows. In experiment 1, data from 5,607 lactating cows enrolled in estrous and …

Ovarian follicular development, hormonal patterns, and fertility were compared for growing
and persistent follicles in 98 lactating dairy cows and in 89 heifers. Pregnancy rates were …

Previous research from our laboratory in beef cattle suggests that ovarian follicle maturity
and subsequent fertility is influenced by length of proestrus across a range of follicle sizes …

Differences in follicular development and circulating hormone concentrations, between
lactating cows and nulliparous heifers, that may relate to differences in fertility between the …
