Abstract
BACKGROUND The aim of this study was to investigate late follicular progesterone (P) serum levels in women with a low number of preovulatory follicles in the assisted reproductive technologies (ART) setting. METHODS Fifty-five consecutive women having four or fewer preovulatory follicles of >14 mm on the day of human chorionic gonadotropin (hCG) administration were prospectively evaluated. Spearman correlation tests were performed between serum estradiol (E2) level, serum P level, P/E2 ratio, number of preovulatory follicles, oocytes and embryos. Women enrolled were further divided into two groups in accordance with the P/E2 ratio on the day of hCG administration and compared. RESULTS Serum E2 level correlated positively with P serum level (rs=0.36, P<0.01), number of mature follicles (rs=0.50, P<0.01) and number of oocytes retrieved (rs=0.36, P<0.05), whereas negatively with P/E2 ratio (rs=- 0.68, P<0.01). Likewise, number of preovulatory follicles correlated positively with E2 level (rs=0.50, P<0.01), P level (rs=0.27, P<0.05) and number of oocytes retrieved (rs=0.33, P<0.05), while it correlated negatively with P/E2 ratio (rs=-0.33, P<0.05). Furthermore, women with P/E2 ratio >1 on the day of hCG administration received considerably higher total follicular stimulating hormone (FSH) dosage and achieved significantly lower number of oocytes and embryos as compared to controls. CONCLUSIONS The reverse relationship between number of preovulatory follicles and P/E2 ratio implies that P rise is not only the result of increased steroidogenic activity, but other oocyte-follicle disrupted mechanisms seem to be involved. An exaggerated FSH stimulation appears to disrupt further these mechanisms.

Abstract
BackgroundThe effect of tobacco on breast cancer (BC) is controversial. The purpose of this study was to investigate the relationship between tobacco and BC.MethodsA search was conducted in PubMed, EBSCO, Web of Science and Cochrane Library databases before February 2022. The adjusted odd ratio (OR) and corresponding 95% confidence interval (CI) were used to examine the relationship between active or passive smoking and BC risk.ResultsA total of 77 articles composed of 2,326,987 participants were included for this meta-analysis. Active (OR=1.15, 95% CI=1.11-1.20, p<0.001) and passive (OR=1.17, 95% CI=1.09-1.24, p<0.001) smoking increased the risk of BC in the female population, especially premenopausal BC (active smoking: OR=1.24, p<0.001; passive smoking: OR=1.29, p<0.001), but had no effect on postmenopausal BC (active smoking: OR=1.03, p=0.314; passive smoking: OR=1.13, p=0.218). Active smoking increased the risk of estrogen receptor-positive (ER+) BC risk (OR=1.13, p<0.001), but had no effect on estrogen receptor-negative (ER-) BC (OR=1.08, p=0.155). The risk of BC was positively associated with the duration and intensity of smoking, negatively associated with the duration of smoking cessation. Active smoking increased the risk of BC in the multiparous population (OR=1.13, p<0.001), but had no effect on the nulliparous population (OR=1.05, p=0.432), and smoking before the first birth (OR=1.22, 95% CI=1.17-1.27) had a greater impact on the risk of BC than smoking after the first birth (OR=1.08, 95% CI=1.04-1.12).ConclusionSmoking (active and passive) increased the risk of BC in women. The effect of smoking on BC was influenced by smoking-related factors (duration, intensity, years of quitting), population-related factors (fertility status), and BC subtypes.Systematic Review Registrationidentifier CRD42022322699.

Joint effect of particulate matter and cigarette smoke on women's sex hormones. BMC Womens Health 2022; 22:3. [PMID: 34996432 PMCID: PMC8742359 DOI: 10.1186/s12905-021-01586-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 12/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although relationships between exposure to air pollution and reproductive health are broadly studied, mechanisms behind these phenomena are still unknown. The aim of the study was to assess whether exposure to particulate matter (PM10) and tobacco smoking have an impact on menstrual profiles of 17β-estradiol (E2) and progesterone (P) and the E2/P ratio. METHODS Levels of sex hormones were measured daily in saliva during the entire menstrual cycle among 132 healthy, urban women. Exposure to smoking (active or passive) was assessed by questionnaire, whilst exposure to PM10 with municipal monitoring data. RESULTS During the early luteal phase, profiles of E2 were elevated among women with higher versus lower exposure to PM10 (p = 0.02, post-hoc tests). Among those who were exposed versus unexposed to tobacco smoking, the levels of mean E2 measured during the entire cycle were higher (p = 0.02). The difference in mean E2 levels between the group of joint exposure (i.e. to high PM10 and passive or active smoking) versus the reference group (low PM10, no smoking) was statistically significant at p = 0.03 (18.4 vs. 12.4 pmol/l, respectively). The E2/P ratios were higher among women with higher versus lower exposure to PM10 and this difference was seen only in the early luteal phase (p = 0.01, exploratory post-hoc tests). CONCLUSIONS We found that PM10 and tobacco smoking affect ovarian hormones independently and do not interact with each other. Both exposures appear to have estrogenic effects even though women's susceptibility to these effects differs across the menstrual cycle. We propose that the hormonal mechanisms are involved in observed relationships between air pollution and smoking with women's reproductive health.

The role of progesterone/estradiol ratio in exploring the mechanism of late follicular progesterone elevation in low ovarian reserve women. Med Hypotheses 2019; 125:126-128. [PMID: 30902140 DOI: 10.1016/j.mehy.2019.02.047] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Revised: 02/04/2019] [Accepted: 02/27/2019] [Indexed: 11/22/2022]
Abstract
Late follicular progesterone (P) elevation continues to complicate a significant part of assisted reproductive technologies (ART) cycles, despite the ardent employment of gonadotropin releasing hormone (GnRH) analogues. In women with good ovarian reserve, late follicular P elevation is believed to be the result of the controlled ovarian stimulation (COS) itself, multiple follicular development and excessive ovarian steroidogenic activity. These mechanisms do not seem to be plausible in women with low ovarian reserve. In these women, excessive COS achieve a small number of pre-ovulatory follicles, which is not coupled to considerable ovarian steroidogenic activity. Therefore, other mechanisms should be pursued and explored. Delicate paracrine and autocrine mechanisms within the oocyte-cumulus complex were suggested to preserve the integrity of the pre-ovulatory follicle, including inhibition of P increase and follicular luteinization. However, clinical studies to demonstrate the disruption of these mechanisms in cases with low ovarian reserve and ageing oocytes are still lacking. Late follicular progesterone/estradiol (P/E2) ratio was introduced into clinical practice as a more appropriate way to analyze P rise in women undergoing COS to control for the E2 increase. The current hypothesis claims that in a follicular environment were the mechanism that prevent premature luteinization is disrupted, independent to LH surge; P rise at the late follicular phase may relatively bypass normal E2 production, at the pre-ovulatory stage of steroidogenesis, causing a rise in the P/E2 ratio. Therefore, in women with low ovarian reserve and few pre-ovulatory follicles, undergoing conventional COS, a negative (reverse) correlation between number of maturing follicles and P/E2 ratio may support the existence of such a mechanism as its disruption, while a no or a positive correlation may disapprove it.

Abstract
This study investigates the predictive power of serum progesterone/estradiol (P/E2) level for estimating the live birth rate in patients who had a serum progesterone (P) rate ≥ 1.5 ng/mL on the human chorionic gonadotropin (hCG) administration day and who received the gonadotropin-releasing hormone (GnRH) antagonist protocol and intracytoplasmic sperm injection (ICSI). This retrospective cohort study included 176 cycles. The P/E2 ratio was lower in patients with a live birth (0.73 ± 0.54) than those without a live birth (1.05 ± 1.38), but the difference was not statistically significant (p = .158). According to the receiver operating characteristic curve analysis of the hCG day P/E2 ratio, the area under the curve was 0.579 (95% confidence interval: 0.478 - 0.680, p = .158) for predicting live birth. In conclusion, this study suggests that a P/E2 ratio is not a significant predictor of a live birth rate in the patients with an hCG-day serum progesterone level of ≥1.5 ng/mL undergoing GnRH antagonist ICSI cycles with a fresh embryo transfer. Impact statement What is already known on this subject? As the progesterone (P) levels in the late follicular phase correlate with the estradiol (E2) levels and the increase in mature follicles, earlier studies have proposed the trigger-day progesterone/estradiol (P/E2) ratio as a potential new marker for a premature luteinisation and live birth success. Most of these studies were conducted on long agonist cycles, and found that arbitrarily defined P/E2 ratio of >1 to be associated with poor pregnancy outcomes. What do the results of this study add? This study retrospectively examines the gonadotropin-releasing hormone (GnRH) antagonist cycles with a trigger-day serum P value of ≥1.5 ng/mL undergoing the intracytoplasmic sperm injection (ICSI) treatment. The receiver operating characteristic (ROC) curve analysis did not identify a statistically significant threshold value for the trigger-day P/E2 ratio that was beneficial in predicting a live birth. The P/E2 ratio was also lower in the cycles with a live birth than those without a live birth, although the difference was not statistically significant. What are the implications of these findings for clinical practice and/or further research? The trigger-day P/E2 ratio does not seem to be an efficient prognostic factor for a live birth in the GnRH antagonist ICSI cycles with a trigger-day serum progesterone level of ≥1.5 ng/mL. Further studies are needed to clarify the association of the trigger-day P/E2 ratio and the pregnancy outcomes in GnRH antagonist ICSI cycles.

Abstract
BACKGROUND The effect of elevated progesterone level on human chorionic gonadotropin (HCG) day in in vitro fertilization cycles is controversial. Some suppose that rise in progesterone level seems to have a negative impact on implantation and pregnancy by desynchronizing the endometrium, while others disagree. OBJECTIVE To evaluate the superiority of the frozen cycle over fresh cycle on live birth in patients with elevated progesterone level on HCG day. MATERIALS AND METHODS In this double-blind, randomized clinical trial, 72 women undergoing assisted reproductive technology with elevated progesterone level (≥1.8 ng/dl) on HCG day were included. The participants were grouped by fresh versus frozen embryo transfer, randomly. Finally, the clinical pregnancy and live birth rate were compared. RESULTS The implantation rate was 21.51%. The clinical pregnancy rate was 47.22% in fresh embryo transfer group (17/36) and 41.66% in frozen group (15/36) (p=0. 40). The live birth rate was not significantly difference between two groups (p=0.56). CONCLUSION None of the fresh and frozen cycles are superior to the other and we recommend individualizing the decision for each patient. The frozen cycle may impose more emotional stress on patients.
