Objective: To investigate the effect of two postoperative doses of estradiol valerate (2 and 4 mg/day) on reproductive outcomes in patients with moderate to severe intrauterine adhesions (IUAs).
Methods: A retrospective cohort study was conducted at a single tertiary reproductive medical center between January 2018 and December 2019 to compare the reproductive outcomes of two doses of estradiol valerate (2 and 4 mg daily) after hysteroscopic adhesiolysis. All patients received adjuvant postoperative treatment with a Foley catheter, hyaluronic acid gel, and medication therapy. Hysteroscopy was repeated every 7 days after surgery. Multivariate regression analysis and propensity score matching (PSM) were performed to minimize intrinsic bias.
Results: A total of 212 patients with moderate to severe IUAs were included: 74 patients received 2 mg of estradiol valerate daily and 138 patients received 4 mg of estradiol daily postoperatively. No significant differences were found in the reproductive outcomes between the two groups, including clinical pregnancy rates. The multivariable regression analyses both before and after PSM also showed that there was no significant difference in the menstrual improvement and clinical pregnancy rates between the two groups.
Conclusions: We suggest the use of a lower dose (2 mg/day) of estradiol valerate as an adjuvant therapy for IUAs to minimize estrogen-related side effects.

Yeast sex-hormone whole-cell biosensors are analytical tools characterized by long-time storage and low production cost. We engineered compact β-estradiol biosensors in S. cerevisiae cells by leveraging short (20-nt long) operators bound by the fusion protein LexA-ER-VP64-where ER is the human estrogen receptor and VP64 a strong viral activation domain.

Scabiosa artropurperea, a member of the Dipsacaceae family and Scabiosa genus, is renowned for its medicinal properties. In the present study, we investigated the impact of Scabiosa artropurperea aqueous extract (AES) on the in vivo reproductive functions in Queue Fine de l'Ouest ewes, and on in vitro ovine granulosa cells. Ewes were synchronized for 14 days with intra-vagina progesterone (P4) devices (FGA, 20 mg) and divided into four groups receiving daily oral doses of 0, 1, 2, and 4 mg of AES/kg Live Body Weight (LBW), respectively.

The smoking cessation drug cytisine exerts neuroprotection in substantia nigra pars compacta (SNc) dopaminergic (DA) neurons of female but not male 6-hydroxydopamine (6-OHDA) lesioned parkinsonian mice. To address the important question of whether circulating 17β-estradiol mediates this effect, we employ two mouse models aimed at depleting systemically circulating 17β-estradiol: (i) bilateral ovariectomy (OVX), and (ii) aromatase inhibition with systemically administered letrozole. In both models, depleting systemically circulating 17β-estradiol in female 6-OHDA lesioned parkinsonian mice results in the loss of cytisine-mediated neuroprotection as measured using apomorphine-induced contralateral rotations and SNc DA neurodegeneration.

Background: Estrogens, such as 17β-estradiol, are the primary female sex hormones predominantly synthesized by mature ovarian follicular cells. The natural exhaustion of ovarian follicular cells during menopause causes a rapid decline in endogenous estrogen levels. This decline in estrogen levels is associated with an increase in chronic, age-related pathologies, including inflammation in the brain.
