Cannabidiol (CBD) but not tetrahydrocannabinol (THC) dysregulate in vitro decidualization of human endometrial stromal cells by disruption of estrogen signaling

In this study, we investigated the effects of phytocannabinoids, tetrahydrocannabinol (THC) and cannabidiol (CBD), in proliferation and differentiation of ESCs, as well as, in E2 metabolism/signaling. We found that CBD, but not THC, inhibits ESCs differentiation. We also show that CBD prevents the increase on transcript levels of CYP19A1 gene and the elevation of E2 levels that are observed in differentiating ESCs. Moreover, we found that CBD presents anti-aromatase activity. In overall, we highlight a novel effect of CBD on human endometrial differentiation, which may lead to infertility problems.

Effect of thyroxine treatment on pregnancy outcomes in infertile Japanese women with TSH levels between 2.5 μIU/mL and the upper reference limit: a retrospective study. Endocr J. 2020 Oct 01;: Authors: Tsunemi A, Uchida T, Kuroda K, Ikemoto Y, Ochiai A, Goto H, Sugiyama R, Satoh H, Itakura A, Watada H Abstract Recent randomized controlled studies have revealed that levothyroxine (LT4) treatment improves pregnancy outcomes only in infertile women with subclinical hypothyroidism who have thyroid autoantibodies (TAs), but not for those with high TSH levels within the normal range who have TAs. Here, we...

ConclusionsThis study demonstrates an objective observation of sleep time reduction in women with subfertility, although it is not yet clear if this association is casual. Given our increased understanding of the internal body clock and circadian rhythm on fertility, our observation warrants further investigation.

AbstractAutoimmune thyroid disease is the most common endocrine disorder during pregnancy. Thyroid autoantibodies (TAs) have been suggested to serve a role in implantation failure and spontaneous abortion. Until now, there are no data on the potential interaction of TAs with human reproductive organs. Here, we set out for the first time to test this hypothesis by studying the expression of thyroid peroxidase (TPO) at gene and protein level in human reproductive organs. Endometrial samples were taken from normal women, and placenta tissues were collected after full-term caesarian section. Expression of TPO messenger RNA (mR...

BackgroundThe risk of adverse pregnancy outcomes is increased by having a polycystic ovary syndrome (PCOS) diagnosis. However, the confounders in previous studies preclude firm conclusions, and further studies are warranted.ObjectivesTo investigate whether PCOS affects pregnancy outcomes and complications in infertile women undergoing their first in vitro fertilization (IVF) treatment, taking into account important confounders.MethodsWe performed a retrospective cohort study of 7,678 infertile women, including 666 women with PCOS and 7,012 controls undergoing their first IVF treatment at a private fertility center from Jan...

by Nathan Riley " Can you all, please, just leave us alone? "One particular experience with the death of a newborn stands out in my mind. Moments after birth the baby was breathless, and the neonatology team could not intubate. All of the kingdom ’s pediatric surgeons and other specialists rushed to labor and delivery to no avail. The baby was born with a four centimeter gap in his trachea, an irreparable condition. The mother sat there, holding her dying baby as he took his last breaths while physicians, nurses, and residents were busy as usual. Click-clacking away on computers. Adjusting blankets. As...

Conclusion: High-normal TSH levels did not significantly influence reproductive outcomes in infertile women undergoing the first single fresh D5 blastocyst transfer. Further studies are needed to test whether the results might be applicable to a wider population. PMID: 32908501 [PubMed]

For frozen embryo transplantation patients who failed to use hormone replacement cycle (HRC) transplantation for 2 consecutive times, the third time of transplantation was divided into 2 groups: HRC and natural cycle (NC), and the pregnancy rate of the 2 groups, especially the clinical pregnancy rate, was compared. Retrospective study of 174 patients in the reproductive medicine center of an affiliated hospital of Shandong University of Traditional Chinese Medicine between January 2015 and September 2018. The 174 patients were all infertile with regular menstruation. They had undergone 2 consecutive failed cycles of endo...

CONCLUSIONS: Until now, diagnosis, prevalence, and clinical relevance on reproductive outcomes in women with T-shaped uterus is unknown. Expectant management must be considered the most appropriate choice for daily practice until randomized controlled trials shows otherwise. This article is protected by copyright. All rights reserved.

AbstractOver the past 2 decades, more women in the United States are engaging in excessive alcohol use, including women of reproductive age. Consuming alcohol in amounts greater than recommended limits is associated with an increased risk for adverse health effects, such as breast cancer, hypertension stroke, spontaneous abortion, and infertility. Any amount of alcohol use during pregnancy can result in a fetal alcohol spectrum disorder. No safe time, safe amount, or safe type of alcohol to consume during pregnancy has been identified. Contradictory beliefs about alcohol use, fear of stigmatization, and potential legal con...
