The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

Journal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Antral follicle responsiveness assessed by follicular output RaTe(FORT) correlates with follicles diameter [PDF]

Journal of Ovarian Research, 2019
The antral follicle count is a marker of ovarian reserve. Follicular Output RaTe (FORT) evaluates the proportion of follicles responsive to exogenous follicle stimulating hormone (FSH) during controlled ovarian stimulation. Our objective was to evaluate whether the diameter (AFC6: ≤ 6 mm or AFC > 6: > 6 mm) of the follicular cohort could be a predictor

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Change in the ability of bovine granulosa cells to elongate transzonal projections and their transcriptome changes during follicle development

The Journal of Reproduction and Development
Granulosa cells (GCs) in secondary follicles differentiate into cumulus cells (CCs) and mural granulosa cells (MGCs) in the antral follicle. Only CCs maintain direct connections with oocytes through transzonal projections (TZPs) and support oocyte growth.

Antral follicle size in the downregulated cycle and its relation to in vitro fertilization outcome

Journal of Human Reproductive Sciences, 2009
Aim: In this study, we have attempted to relate the antral follicle size on day 3 of downregulation to the in vitro fertilization (IVF) outcome and hence test its predictive value for IVF outcome.

Three-Dimensional Micro-Computed Tomography of the Adult Mouse Ovary

Frontiers in Cell and Developmental Biology, 2020
In the mouse ovary, folliculogenesis proceeds through eight main growth stages, from small primordial type 1 (T1) to fully grown antral T8 follicles. Most of our understanding of this process was obtained with approaches that disrupted the ovary three ...

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Di (2-ethylhexyl) Phthalate Exposure Impairs Growth of Antral Follicle in Mice. [PDF]

PLoS ONE, 2016
Di (2-ethylhexyl) phthalate (DEHP) is a widely used plastic additive. As an environmental endocrine disruptor, it has been shown to be harmful to the mammalian reproductive system.

Di(2-ethylhexyl) phthalate inhibits antral follicle growth, induces atresia, and inhibits steroid hormone production in cultured mouse antral follicles [PDF]

Toxicology and Applied Pharmacology, 2015
Di(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental toxicant found in consumer products that causes ovarian toxicity. Antral follicles are the functional ovarian units and must undergo growth, survival from atresia, and proper regulation of steroidogenesis to ovulate and produce hormones.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native
