Timed-AI after synchronization of ovulation has become one of the most used reproductive
technologies developed during the past 40 years. Various adaptations of this technology are …

Fixed-time artificial insemination (FTAI) has been regarded as the most useful method to
increase the number of cows inseminated in a given herd. The main treatments for FTAI in …

The study of follicular dynamics began in the mid-20th century, but progress has been
particularly rapid in the last two decades through the use of tools that have enabled serial …

In this review, the main features of folliculogenesis are summarized and compared among
species. In the past few years, ultrasonography has clarified follicle growth patterns, and our …

Superovulation protocols have evolved greatly over the past 40 to 50 years. The
development of commercial pituitary extracts and prostaglandins in the 1970s, and partially …

Our expanding knowledge of the control of follicular wave dynamics during the bovine
estrous cycle has resulted in renewed enthusiasm for the prospects of precisely controlling …

The variability in the superovulatory response continues to be one of the most frustrating
problems with embryo transfer in cattle. The removal of LH from pituitary extracts has tended …

To achieve precise control of the oestrous cycle in cattle it is necessary to control both the
life span of the corpus luteum and the follicle wave status at the end of the treatment. Antral …

An experiment was designed to evaluate the effects of treatment with progestogen and
estradiol-17β (E-17β), in combination, at different stages of development of the dominant …

We tested the hypotheses that:(1) the superstimulatory response is related to the intrinsic
number of follicles recruited into a follicular wave; and (2) the number of follicles recruited …
