Objective: To determine the association between biomarkers of ovarian reserve and luteal phase deficiency (LPD).
Design: Secondary analysis of a prospective time-to-conceive cohort study.
Setting: Not applicable.
Patient(s): Women attempting conception, aged 30-44 years, without known infertility.
Intervention(s): Measurement of early follicular phase serum levels of antimüllerian hormone, FSH, inhibin B, and E.
Main Outcome Measure(s): The primary outcome was LPD, defined by luteal bleeding (LB) (≥1 day of LB) or a short luteal phase length (≤11 days).
Result(s): Overall, 755 women provided information on 2,171 menstrual cycles and serum for measurement of at least one biomarker of ovarian reserve. There were 2,096 cycles from 754 women in the LB cohort, of which 40% experienced LB. After adjusting for age, race, previous miscarriages, and previous pregnancies, diminished ovarian reserve (DOR) was not significantly associated with LB. Low early follicular phase FSH levels increased the odds of LB (odds ratio [OR] 1.84; 95% confidence interval [CI] 1.25-2.71), as did high early follicular phase E levels (OR 1.59; 95% CI 1.26-2.01). A total of 608 cycles from 286 women were included in the analysis of luteal phase length, of which 13% had a short luteal phase. After adjusting for age, there was no significant association between DOR and a short luteal phase. The risk of a short luteal phase decreased with increasing inhibin B (OR 0.61; 95% CI 0.45-0.81).
Conclusion(s): Although DOR is not associated with LPD, hormone dysfunction in the early follicular phase may contribute to LPD in women of older reproductive age.

An important part of the side effects of combined oral contraceptives (COC) usage is its psychological impact, which includes mood changes, anxiousness and depression. The psychological impacts are expected to be caused by physiological fluctuations of sex hormone levels during the menstrual cycle; this cycling is, however, suppressed in COC users. In our study, we assessed the differences in emotional awareness and anxiousness between women long term users of anti-androgenic COC (AA) and women with no COC use in their medical history (C).

Seed cycling therapy (SCT) involves the consumption of specific seeds during the follicular and luteal phases of the menstrual cycle to help balance reproductive hormones. This study aimed to investigate the effects of SCT on healthy female Wistar albino rats to prevent hormonal imbalances. For SCT, a seed mixture (SM1) consisting of flax, pumpkin, and soybeans (estrogenic seeds) was administered at doses of 5.

Study Question: Is there an association between dydrogesterone exposure during early pregnancy and the reporting of birth defects?
Summary Answer: This observational analysis based on global safety data showed an increased reporting of birth defects, mainly hypospadias and congenital heart defects (CHD), in pregnancies exposed to dydrogesterone, especially when comparing to progesterone.
What Is Known Already: Intravaginal administration of progesterone is the standard of care to overcome luteal phase progesterone deficiency induced by ovarian stimulation in ART. In recent years, randomized controlled clinical trials demonstrated that oral dydrogesterone was non-inferior for pregnancy rate at 12 weeks of gestation and could be an alternative to micronized vaginal progesterone.

Women may be challenged to maintain thermoregulation due to hormonal changes associated with the menstrual cycle. The purpose of this study was to assess the effect of the menstrual cycle phase on core temperature, hydration status, and perceived exertion while exercising under uncompensable heat gain. Eleven eumenorrheic women (24.

Background: Alterations in lipid metabolism were reported to impact human fertility; however, there is limited evidence on the association of lipid metabolism with embryo implantation as well as the etiology of recurrent implantation failure (RIF), especially regarding arachidonic acid metabolism.
Methods: Experimental verification research (16 RIF patients and 30 control patients) based on GEO database analysis (24 RIF patients and 24 control patients). The methods in bioinformatics included differential gene screening, functional enrichment analysis, protein-protein interaction network, cluster analysis, weighted gene co-expression network analysis, and so forth.
