Leukemia Inhibitory Factor Represses GnRH Gene Expression via cFOS during Inflammation in Male Mice. [PDF]

, 2019
BackgroundThe mechanisms whereby neuroinflammation negatively affects neuronal function in the hypothalamus are not clear. Our previous study determined that obesity-mediated chronic inflammation elicits sex-specific impairment in reproductive function ...

Regulation of reproduction via tight control of gonadotropin hormone levels. [PDF]

, 2018
Mammalian reproduction is controlled by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus regulates synthesis and secretion of gonadotropins, LH and FSH, which then control steroidogenesis and gametogenesis. In females, serum LH and FSH

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, EarlyView.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Final oocyte maturation with a dual trigger compared to human chorionic gonadotropin trigger in antagonist co-treated cycles: A randomized clinical trial

Middle East Fertility Society Journal, 2018
Objective: This clinical trial compared the effect of a dual trigger treatment (combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (hCG) and hCG alone on oocyte quality and metaphase II oocytes’ number. Methods:

Bioengineered Isoflavone–Probiotic Functional Foods for Sustainable Modulation of Metabolic and Reproductive Health in PCOS

Food Bioengineering, EarlyView.
Synergistic isoflavone‐probiotic action modulated metabolic, microbial and ovarian pathway ABSTRACT Polycystic ovary syndrome (PCOS) is a prevalent metabolic–endocrine disorder characterized by insulin resistance, hyperandrogenism, chronic inflammation, oxidative stress, and ovarian dysfunction, with growing evidence implicating gut microbiota ...

Regulation of Gonadotropin-Releasing Hormone-(1–5) Signaling Genes by Estradiol Is Age Dependent

Frontiers in Endocrinology, 2017
Gonadotropin-releasing hormone (GnRH) is a key regulatory molecule of the hypothalamus–pituitary (PIT)–gonadal (HPG) axis that ultimately leads to the downstream release of estradiol (E2) and progesterone (P).

Successful outcome of a pregnancy derived from premature ovulation in a gonadotropin‐releasing hormone antagonist protocol: A case report

Clinical Case Reports, 2021
In the gonadotropin‐releasing hormone (GnRH) antagonist protocol, it is necessary to reinforce contraceptive guidance assuming that luteinizing hormone surge is not detected by measurement of serum level and ovulation is not suppressed by GnRH antagonist.

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]

, 2013
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Micro‐and nanoplastics (MNPs) are breakdown products of plastics, and humans are exposed to these particles through air, water, food, and soil. There is a growing concern that human exposure to MNPs negatively impacts health. In this review we will discuss the potential health impact of MNPs on ovarian function and the hypothalamic–pituitary ...
