Follicular Waves in the Human Ovary: A New Physiological Paradigm for Novel Ovarian Stimulation Protocols
(Sage Publications Inc, 2010-12-01)
Ovulation induction (OI) is a cornerstone of human assisted reproduction treatments (ART). Current OI protocols are based on the human follicular dynamics model known as propitious moment theory (PMT), by which follicles ...
Progestin-based protocol for synchronization of follicular wave emergence in buffaloes during summer and winter
(2013-12-01)
The aim of the present study was to evaluate the effects of type of norgestomet auricular implant (new-N or previously used during 5 days-U), season of the year (summer-S and winter-W), and parity (12 heifers-H and 23 ...
Progestin-Based Protocol for Synchronization of Follicular Wave Emergence in Buffaloes During Summer and Winter
(Int Buffalo Information Ctr, 2013-01-01)
The aim of the present study was to evaluate the effects of type of norgestomet auricular implant (new - N or previously used during 5 days - U), season of the year (summer - S and winter - W), and parity (12 heifers - H ...
Follicular wave dynamics and Growth factors gene expression in Braford heifers
(Wiley Blackwell Publishing, Inc, 2020-11)
The objectives of the present study were (experiment 1) to characterized development and dynamics of the dominant follicles (DF) and the corpus luteum (CL) to determine patterns of two (W2) and three (W3) follicular waves ...
Plasma IGF1 and 17β-Estradiol Concentrations During the Follicular Wave in Llamas
(Frontiers Media S.A., 2020-10)
The aim of this study was to characterize the temporal association between follicular waves and circulating concentrations of 17β-estradiol (E2) and IGF1 in llamas. Follicular waves could be clearly divided in three phases: ...
Ovarian follicular dynamics and hormonal secretory profiles in guanacos (Lama guanicoe)
(ELSEVIER SCIENCE BV, 2010)
The objective of the present study was to describe ovarian activity in 11 adult non-mated guanacos, evaluated every second day for 40 days by transrectal ultrasonography and by plasma estradiol-17 beta and progesterone ...
Follicular wave emergence in Santa Ines ewes subjected to long-term, progesterone-based estrous synchronization protocols at different times of the year
(Elsevier B.V., 2016-11-01)
This study was conducted to document the pattern of antral follicular wave emergence throughout the 14-day, progesterone (P-4)-based estrous synchronization protocol in ewes that were maintained in subtropical conditions, ...
Ultrasonographic and endocrine characterization of follicular waves in llamas with a special reference to the overlapping phenomenon during successive waves
(Wiley-blackwell Publishing, Inc, 2013-06)
Ovarian follicular growth in non-mated llamas occurs in successive waves that generally superimpose their origin on the regression of the preceding wave (overlapping), originating prolonged sexual receptivity in the ...
