Hypothalamus Transcriptome Reveals Key lncRNAs and mRNAs Associated with Fecundity in Goats

Animals
The hypothalamus (hyp) serves as the regulatory hub of the neuroendocrine system, synthesizing and secreting reproductive hormones that modulate estrus, follicular maturation, and embryonic development in goats.

Subjecting holstein heifers to stress during the follicular phase following superovulatory treatment may increase the female sex ratio of embryos.

Journal of reproduction and development, 2009
The sex ratio of mammals has previously been shown to be affected by maternal stress. In our previous study, the proportion of female embryos collected from superovulated and artificially inseminated Holstein heifers that were frequently placed in ...

Changes in epithelial proportions and transcriptional state underlie major premenopausal breast cancer risks [PDF]

, 2018
The human breast undergoes lifelong remodeling in response to estrogen and progesterone, but hormone exposure also increases breast cancer risk. Here, we use single-cell analysis to identify distinct mechanisms through which breast composition and cell ...

Power in the flow: how menstrual experiences shape women's strength training performance

Frontiers in Sports and Active Living
IntroductionHormone levels fluctuate significantly throughout the menstrual cycle (MC), potentially impacting physical performance during training. However, the number of studies examining women's experiences during strength training throughout the MC is

Double or dual stimulation in poor ovarian responders: where do we stand?

Therapeutic Advances in Reproductive Health, 2021
Recent advances in our recognition of two to three follicular waves of development in a single menstrual cycle has challenged the dogmatic approach of ovarian stimulation for in vitro fertilization starting in the early follicular phase.

Nocturnal slowing of pulsatile luteinizing hormone secretion in women during the follicular phase of the menstrual cycle.

Journal of Clinical Endocrinology and Metabolism, 1985
The gonadotropin secretion pattern in normal reproductive age women (n = 5) was evaluated for the presence of a circadian rhythm. The women volunteered for a series of 24-h admissions in different phases of their menstrual cycles (early follicular, late ...

Ovarian function during hormonal contraception assessed by endocrine and sonographic markers: a systematic review [PDF]

, 2016
This systematic review focuses on the literature evidence for residual ovarian function during treatment with hormonal contraceptives. We reviewed all papers which assessed residual ovarian activity during hormonal contraceptive use, using endocrine ...

Biometrical parameters of internal female genitalia in western Libyan Barbary sheep

Open Veterinary Journal
Background: In Libya, the Barbary sheep plays an important role in livestock as a source of meat and wool. Improving animal production requires knowledge and understanding of the female reproductive system.

Perturbations in Lineage Specification of Granulosa and Theca Cells May Alter Corpus Luteum Formation and Function [PDF]

, 2019
Anovulation is a major cause of infertility, and it is the major leading reproductive disorder in mammalian females. Without ovulation, an oocyte is not released from the ovarian follicle to be fertilized and a corpus luteum is not formed.

Species-specific differences in follicular antral sizes result from diffusion-based limitations on the thickness of the granulosa cell layer

, 2013
The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters more than 1000-fold the size of the enclosed oocyte.
