A H Souza et al.
Theriogenology, 72(1), 10-21 (2009-03-10)
The objectives were to evaluate the effects of equine chorionic gonadotropin (eCG) supplementation (with or without eCG) and type of ovulatory stimulus (GnRH or ECP) on ovarian follicular dynamics, luteal function, and pregnancies per AI (P/AI) in Holstein cows receiving
Ocilon Gomes Sá Filho et al.
Animal reproduction science, 112(1-2), 95-106 (2008-05-13)
Three experiments evaluated effects of estradiol (E(2)) and/or progesterone (P(4)) prior to induction of ovulation with GnRH on subsequent luteal lifespan in anestrous Nelore cows. In Experiment 1, cows (25-65 days post-partum [DPP]; n=114) were assigned randomly to receive a

Human reproduction (Oxford, England), 24(11), 2688-2692 (2009-07-30)
The aromatase inhibitor, letrozole, exerts embryo toxic effects in rats, causing increased embryo lethality and anomalies of the axial skeleton at pharmacologically relevant doses. Letrozole acts by inhibiting estrogen biosynthesis. It may thus be feasible that estrogen deprivation is a
José Alfredo Sierra-Ramírez et al.
Contraception, 84(6), 565-570 (2011-11-15)
The efficacy of contraceptives is affected by its route and ease of administration. Herein, both pharmacokinetics and pharmacodynamics of the once-a-month combined injectable contraceptive medroxyprogesterone acetate (MPA) plus estradiol cypionate (E(2)-Cyp) were compared after intramuscular (IM) or subcutaneous (SC) injection
A D P Rodrigues et al.
Theriogenology, 79(1), 135-141 (2012-11-06)
Four experiments were conducted to evaluate hormonal strategies to induce ovulation in Nellore heifers. In experiment 1, heifers (N = 1039) received a controlled internal drug release (CIDR) of fourth use (CIDR-4) on Day -12 or no CIDR (CIDR-0). The
