Recombinant bovine somatotropin in the synchronization of ovulation in crossbred dairy cows (Bos taurus indicus × Bos taurus taurus) [PDF]
Veterinary World, 2020 Aim: The aim of this study was to evaluate the effects of the administration of recombinant bovine somatotropin (rbST) at the moment of implementation of the timed artificial insemination protocol, on follicular dynamics and pregnancy rate in crossbred ...

Computer-Generated Ovaries to Assist Follicle Counting Experiments [PDF]
, 2015 Precise estimation of the number of follicles in ovaries is of key importance in the field of reproductive biology, both from a developmental point of view, where follicle numbers are determined at specific time points, as well as from a therapeutic ...

Age as A Predictor of Embryo Quality Regardless of The Quantitative Ovarian Response [PDF]
International Journal of Fertility and Sterility, 2017 Background One determining factor of a successful in vitro fertilization (IVF) cycle is embryo quality. The aim of the present study was to evaluate associations of embryo quality and reserve markers like age, FSH and AMH.

Control of antral follicle development and selection in sheep and cattle.
Journal of reproduction and fertility. Supplement, 2019 The development of antral follicles in sheep and cattle is dependent on FSH, but large antral follicles can shift their gonadotrophic dependence from FSH to LH. The mechanisms that result in the selection of at least one ovulatory follicle from identical

Effect of androgen treatment during foetal and/or neonatal life on ovarian function in prepubertal and adult rats [PDF]
, 2012 We investigated the effects of different windows of testosterone propionate (TP) treatment during foetal and neonatal life in female rats to determine whether and when excess androgen exposure would cause disruption of adult reproductive function ...

Role of oestradiol in growth of follicles and follicle deviation in heifers [PDF]
Reproduction, 2003 Follicle deviation is characterized by continued growth of the largest (developing dominant) follicle and reduced growth of the smaller (subordinate) follicles. The aim of the present study was to test the following hypotheses: (1). oestradiol contributes to the depression of circulating FSH encompassing follicle deviation and (2).

A new flow-based design for double-lumen needles [PDF]
Journal of Biomechanics 160, 111832, 2023, 2023 Oocyte retrieval forms a crucial part of in vitro fertilisation treatment and its ultimate outcome. Standard double-lumen needles, which include a sequence of aspiration and flushing steps, are characterised by a similar success rate to single-lumen needles, despite their increased cost.

Empirically inspired simulated electro-mechanical model of the rat mystacial follicle-sinus complex [PDF]
, 2004 In whiskered animals, activity is evoked in the primary sensory afferent cells (trigeminal nerve) by mechanical stimulation of the whiskers. In some cell populations this activity is correlated well with continuous stimulus parameters such as whisker ...

Mechanisms regulating follicular development and selection of the dominant follicle.
Reproduction (Cambridge, England) Supplement, 2019 Reproductive function is an integrated process encompassing both extra-ovarian signals, such as gonadotrophins, and intrafollicular factors, such as locally produced growth factors.
