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.

Comparative Analysis of the Progesterone Receptor Interactome in the Human Ovarian Granulosa Cell Line KGN and Other Female Reproductive Cells

PROTEOMICS, EarlyView.
ABSTRACT The nuclear steroid hormone receptor progesterone receptor (PGR) is expressed in granulosa cells in the ovarian follicle in a tightly regulated pattern in response to the surge of luteinizing hormone (LH) that stimulates ovulation. PGR plays a critical role in mediating ovulation in response to LH, however, the mechanism for this is still ...

Atomic Force Microscopy Reveals Differences In Mechanical Properties Linked To Cortical Structure In Mouse And Human Oocytes

Small, EarlyView.
Using Atomic Force Microscopy, the link between oocyte mechanical properties and actin cortex organization is investigated. In mouse oocytes, a thin actin cortex results in stiffer oocytes, while a thicker cortex leads to softer ones. Maternal age affects oocyte mechanics by altering cortex structure.

Emerging trends in the management of non‐obstructive azoospermia

UroPrecision, EarlyView.
Abstract Ten percent of infertile males have azoospermia, classified into obstructive and nonobstructive types, which require specific medical or surgical treatments. In nonobstructive azoospermia, advancements in microsurgery allow for effective sperm retrieval in about half of cases.

PACAP induces FSHβ gene expression via EPAC. [PDF]

, 2019
Gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are heterodimers of a common α subunit and unique β subunits. Regulation of their levels, primarily by GnRH, is critical for reproductive function.

Surgical outcomes in male reconstructive urology: The Qatar experience

UroPrecision, EarlyView.
Abstract Introduction Obstructive azoospermia (OA) is a prevalent cause of male infertility in Qatar and globally, with vasectomy reversal (VV) and vasoepididymostomy (VE) being the primary surgical treatments. While microsurgical techniques have advanced, data from the Middle East remain limited, influenced by the region's distinct demographic and ...

Systematic review and meta‐analysis of COVID‐19 association with human semen quality: Changes in semen parameters pre‐ and post‐COVID

UroPrecision, EarlyView.
Abstract Coronavirus disease (COVID‐19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which may infect the cells through binding with the angiotensin‐converting enzyme 2 (ACE2) receptors that can also be found in the male reproductive organs.

Pituitary apoplexy is associated with concurrent or subsequent diagnosis of human immunodeficiency virus

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
Abstract Objective Pituitary apoplexy (PA) is a rare condition caused by hemorrhage or infarction of the pituitary gland with associated risk of cranial neuropathies, endocrinopathies, and even death. Human immunodeficiency virus (HIV) has been shown to have some association with pituitary apoplexy, however, large‐scale studies have not been performed.

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.
