No evidence for a diminished ovarian reserve among patients with hypertensive disorders of pregnancy: a case control study.

BACKGROUND: Existing evidence suggests a relation between cardiovascular dysfunction and diminished ovarian reserve. While it is known that pre-existent cardiovascular dysfunction is also associated with the development of preeclampsia (PE) during pregnancy, we hypothesize that signs of diminished ovarian reserve may occur more frequently among women with a history of hypertensive disorders of pregnancy (HDP). The aim of our study was therefore to analyse if women with a history of HDP show signs of diminished ovarian reserve, represented by lower anti-Mullarian hormone (AMH) levels, compared to controls. For this retrospective observational case control study, patients included women with a history of HDP, whereas controls constituted of women with a history of an uncomplicated pregnancy. The study was conducted in a tertiary referral centre in which all women underwent a one-time cardiovascular and metabolic assessment. Ovarian reserve and markers of cardiovascular function were evaluated, adjusted for age and body mass index (BMI) using linear regression analyses. RESULTS: 163 patients and 81 controls were included over a time span of 3 years. No signs of diminished ovarian reserve i.e. lower AMH level were observed in the patient group versus controls. A subgroup analysis even showed higher AMH levels in late onset HDP as compared to controls (2.8 vs. 2.0 µg/L, p = 0.025). As expected, cardiovascular function markers were significantly less favourable in the patient group compared to controls; higher levels of systolic blood pressure (BP) (5%), diastolic BP (4%), triglycerides (29%), glucose (4%) and insulin levels (81%) (all p < 0.05), whereas high density lipid (HDL) cholesterol was 12% lower (NS). CONCLUSIONS: Despite unfavourable cardiovascular risk profile, the present study does not substantiate the hypothesis that women with HDP show accelerated ovarian ageing as compared to healthy parous controls. Although HDP patients should be warned about their cardiovascular health, they shouldn't be concerned about unfavourable ovarian reserve status.

Considerations of breast cancer survivors to return for embryo transfer after fertility preservation: A qualitative study.

OBJECTIVE: To gain insight into the considerations of breast cancer survivors to return or not for embryo transfer after the use of fertility preservation. STUDY DESIGN: This is a qualitative study with semi-structured interviews. The interviews were planned until saturation of themes had been achieved. Content analysis was used to analyze the data. Sixteen out of 35 approached women took part in this study. Interviews were conducted with women who had oocytes or embryos cryopreserved prior to breast cancer treatment at the Maastricht University Medical Center between 2008 and 2016. All women who had cryopreservation more than two years ago were invited for the interviews. Women who had recurrence of disease were excluded. In the interviews we hypothesized the situation 'suppose the menses would have been recovered completely' for women who still had chemotherapy-induced menopause or used an GnRH (Gonadotropin-releasing hormone) analogue. RESULTS: Most women had a strong intrinsic motivation to pursue natural conception over the use of earlier cryopreserved oocytes or embryos. Time pressure was the most mentioned consideration to use cryopreserved oocytes or embryos. The wish to use pre-implantation genetic testing (PGT) in the presence of a germline BRCA1/2 mutation was another consideration to opt for embryo transfer. Furthermore, the physician's advice was an important motivation to choose for either natural conception or the use of cryopreserved oocytes or embryos. CONCLUSION: Multiple considerations influence women's decision making on the mode of conception after breast cancer. Although it concerned a single-center study in a highly-selected population, insight into these considerations can help physicians to address these important topics in counseling these women.

Preconceptional evaluation of women with recurrent pregnancy loss: the additional value of assessing vascular and metabolic status.

BACKGROUND: A majority of recurrent pregnancy loss cases (RPL) remains unexplained. We hypothesized that complications in vascular and metabolic status may guide towards underlying problems that also predispose to RPL and that the number of pregnancy losses is related. METHODS: A retrospective study in 123 women with either a history of low-order RPL (2-3 pregnancy losses) or high-order RPL (≥ 4 pregnancy losses) and 20 women with a history of uncomplicated pregnancy (controls) was performed. Vascular status was assessed by measuring hemodynamic parameters, determining abnormal parameters and analyzing their contribution to the circulatory risk profile (CRP). In a similar way, metabolic status was assessed. Metabolic parameters were measured, used to determine abnormal parameters and analyzed for their contribution to the metabolic syndrome (MetS). RESULTS: No major differences were observed in vascular or metabolic parameters between women with RPL and controls. There was no relation with the number of pregnancy losses. However, when analyzing the presence of abnormal constituents, more than 80% of women with RPL had at least one abnormal constituent of the CRP. While only 27% had one or more abnormal constituent of the MetS. CONCLUSIONS: The presence of abnormal circulatory factors prior to pregnancy, and to lesser extent constituents of the metabolic syndrome, may predispose to RPL and offer new insights to its pathophysiology.
