Federal guidelines recommend that food with hormone content fall below 1% of endogenous production in the subset of the population with the lowest daily production. The majority of dairy products are obtained from pregnant cows, which increase the level of hormones present. The purpose of this article was to perform theoretical evaluation of the quantity of progesterone in cow's milk based on fat percentages and to assess whether this was within the recommended range. Daily recommended dairy product intake from various countries worldwide was researched. This was compared to the concentration of progesterone previously identified in varying fat contents of cow origin milk to assess the amount of progesterone (mg/day) that would be consumed if the guidelines were followed. The maximum daily progesterone consumption suggested will be met by ingestion of 2.7 L, 1.42 L, 1.13 L, 940 mL, 810 mL, 650 mL of 0% (skim), 1%, 2%, 3.25%, 10% (cream), and 35% (whipping cream) fat liquid cow origin dairy product, respectively. Therefore, ingestion of the highest amount of recommended daily dairy intake fell below 1% of the daily endogenous quantity produced, except in the unlikely case of consumption of 650 mL of 35% fat. Studies demonstrating an effect of cow's liquid dairy product intake may need to be revisited, since levels of progesterone consumption remain within the recommended levels. However, it should be considered that ingestion of cow's milk might have a potential effect on the hormonal profile in patients; however, this seems unlikely.

Objective To evaluate the endometrial histopathological profile of patients undergoing curettage and the association of the histopathological profile with the pregnancy outcome during the subsequent in-vitro fertilization (IVF) cycle. Methods In this retrospective cohort study, a total of 248 women with at least one failed attempt of IVF and who underwent curettage and a subsequent IVF were included. Demographic data, endometrial histopathological records, stimulation information, and pregnancy outcomes were collected and analyzed. Results The histopathological analysis of endometrial tissues showed that 130 women (52.4%) had endometrial pathologies. Of these women, 103 (41.5%) had endometrial polyps, 22 (8.9%) had chronic endometritis, and five (2.0%) had both polyps and endometritis. No statistical difference was observed between the normal histopathology group and the abnormal histopathology group in the outcome of the subsequent IVF cycle. Subgroup analyses were performed to further characterize and compare women with normal histopathology and women with endometrial polyps (polyp subgroup) or chronic endometritis (endometritis subgroup). No statistical differences were found among the three groups in the rates of pregnancy (44.1% vs. 49.5% vs. 45.5%, P=0.72), biochemical pregnancy loss (13.5% vs. 15.7% vs. 20.0%, P=0.86), clinical pregnancy loss (25.0% vs. 31.4% vs. 30.0%, P=0.77), and live birth (27.1% vs. 26.2% vs. 22.7%, P=0.91) during the subsequent IVF cycle. Conclusion Women with previously failed IVF and abnormal endometrial histopathology treated with curettage had the same outcome in the subsequent IVF cycle as women with normal endometrial histopathology.
