Luteinizing hormone profiles during ovarian stimulation in assisted reproductive treatment.
Front Endocrinol (Lausanne)
December 2024
Leuven University Fertility Center, Department of Gynecology and Obstetrics, University Hospitals Leuven, Leuven, Belgium.
Introduction: Few data is available on the natural course of luteinizing hormone (LH) during ovarian stimulation, but it has been suggested that 'oversuppressed' LH could decrease fertility outcomes. Our aim with this study is to evaluate the changes in LH depending on the used stimulation protocol to better define LH oversuppressioin.
Methods: Patients undergoing oocyte retrieval in a tertiary fertility center between 01-01-2015 and 30-09-2020 after stimulation with a short-agonist (SA) or antagonist (A) protocol were included.

Article Synopsis
- The study looked at how effective two different methods of triggering ovulation are for women with fewer eggs (DOR) during in vitro fertilization (IVF).
- Researchers compared a dual-trigger method (using two medications) to a single method (using just one medication) to see if it made any difference in getting better results.
- The results showed that using both methods didn't provide any better outcomes for getting eggs or successful pregnancies than just using the single method alone.

Disorder-Not CHARGE Syndrome-Presenting as Isolated Cochleovestibular Dysfunction.
Genes (Basel)
May 2024
Department of Head and Skin, Faculty of Medicine and Health Sciences, Ghent University Hospital, 9000 Ghent, Belgium.
CHARGE syndrome, characterized by a distinct set of clinical features, has been linked primarily to mutations in the gene. Initially defined by specific clinical criteria, including coloboma, heart defects, choanal atresia, delayed growth, and ear anomalies, CHARGE syndrome's diagnostic spectrum has broadened since the identification of . Variants in this gene exhibit considerable phenotypic variability, leading to the adoption of the term " disorder" to encompass a wider range of associated symptoms.

The influence of body composition on the response to dynamic stimulation of the endocrine pituitary-testis axis.
Int J Obes (Lond)
September 2024
Department of Growth and Reproduction, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.
Article Synopsis
- The study explores how body composition, particularly body mass index (BMI), affects the pituitary-testis axis in men, which is important for understanding testosterone levels.
- Findings show that higher BMI is linked to lower basal levels of luteinizing hormone (LH) and testosterone, indicating potential hormonal dysfunction in men with obesity.
- However, responses to dynamic hormone stimulation tests were less affected by BMI, suggesting that while basal hormone levels are significantly impacted by obesity, the body's ability to produce hormones in response to stimulation remains relatively stable.
Novel insights into minipuberty and GnRH: Implications on neurodevelopment, cognition, and COVID-19 therapeutics.
J Neuroendocrinol
October 2024
Univ. Lille, Inserm, CHU Lille, Laboratory of Development and Plasticity of the Neuroendocrine Brain, Lille Neuroscience & Cognition, UMR_S1172, Lille, France.
Article Synopsis
- - The first 1000 days of life are crucial for brain and overall development, with a phenomenon called minipuberty influencing the hypothalamic-pituitary-gonadal (HPG) axis and reproductive health in humans and other mammals.
- - Recent studies suggest that minipuberty affects not only reproductive functions but also cognitive and sensory maturation, with specific roles of nitric oxide (NO) being identified in this process; cognitive deficits in conditions like Down syndrome may stem from a decline in GnRH production linked to minipuberty.
- - The impact of COVID-19 on GnRH production raises concerns about possible long-term effects on neurodevelopment, as GnRH neurons may be vulnerable to SARS-CoV-2, leading

January 2024
Department of Applied Biomedical Science, Faculty of Health Sciences, University of Malta, Msida, MSD 2080, Malta.
Article Synopsis
- The p.Q106R variant of the gonadotropin-releasing hormone receptor is linked to idiopathic hypogonadotropic hypogonadism (IHH) and was found at a significantly higher frequency in Maltese newborns compared to the global average.
- A study analyzed hormone levels and fertility data from 739 men and 239 women and identified 43 heterozygotes for the p.Q106R variant.
- The findings indicate that p.Q106R heterozygotes do not show abnormal hormone levels or fertility issues, suggesting that additional genetic factors may contribute to IHH in these individuals, and highlighting the variant’s likely founder status in Malta.

J Clin Endocrinol Metab
January 2024
The Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, MD 20892-1932, USA.
Article Synopsis
- Children with congenital adrenal hyperplasia (CAH) are at risk for early puberty, and Gonadotropin-releasing hormone analog (GnRHa) is commonly used to manage this condition despite concerns about bone mineral density (BMD).
- A study was conducted with 61 patients with classic CAH, comparing BMD outcomes between those treated with GnRHa and those who were not, finding no significant differences in BMD at adult height.
- While GnRHa treatment did not negatively impact BMD, there was a noted overall decrease in BMD as patients aged, which may be linked to long-term glucocorticoid use, but the treatment positively influenced height outcomes.

Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, National Clinical Research Center for Obstetric & Gynecologic Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, No.1 Shuai Fu Yuan, Dong Cheng District, Beijing, China.
Article Synopsis
- Pulmonary benign metastasizing leiomyoma (PBML) is the most common extrauterine spread of uterine leiomyoma and is believed to be hormone-dependent, with limited studies focusing on younger women with this condition.
- In a review of 65 cases of PBML in women aged 45 and younger, findings showed that the median age at diagnosis was 39, with most cases presenting as bilateral solid lesions and a significant portion being treated with anti-estrogen therapies.
- Patients who had curative surgery combined with anti-estrogen treatment experienced better outcomes, while some patients benefited from sirolimus, which succeeded in managing symptoms without affecting hormone levels.

Congenital hypogonadotropic hypogonadism (CHH) is a rare disorder that causes gonadotropin-releasing hormone (GnRH) deficiency and sexual immaturity. CHH may accompany an abnormal sense of smell (Kallmann syndrome, KS) or no such manifestation (normosmic-CHH). This unusual combination of manifestations is explained by the fact that GnRH neurons originate in the olfactory placode and migrate to the forebrain during embryogenesis.
