'Do I want children later in life?' Reproductive intentions of 1700 adolescents.

PURPOSE: In the past decades, a positive attitude towards having children has been reported in young people. The current generation of adolescents is increasingly concerned about environmental cataclysm which may have an impact on their desire for children. The purpose of this study is to depict the current attitudes in Flemish adolescents towards having children. MATERIALS AND METHODS: All secondary schools in Flanders (Belgium) were invited to distribute an anonymous online survey among their pupils in the last two years of secondary education. In total, 1700 adolescents participated and provided quantitative and qualitative data on their reproductive intentions. RESULTS: Most pupils expressed a desire for children (60.2%), 24.7% were undecided and 10.8% were not willing to have children. Significantly more boys than girls would like to have children (67.0% versus 61.7%, p < 0.01). Adolescents who were uncertain about having children or not interested, reported financial reasons and loss of freedom as most important reasons. CONCLUSIONS: While most adolescents would like to have children in the future, one in four adolescents is undecided and one in ten indicates a wish to remain childless; reasons for wanting children are rather personal, reasons for not wanting children are rather pragmatic.

A desire for parenthood is no longer the norm: 60% of Flemish adolescents would like to build a family, but many are considering a future without children.

A retrospective study evaluating the impact of scattering radiation from imaging procedures on oocyte quality during ovarian stimulation for fertility preservation in young breast cancer patients.

PURPOSE: Ovarian stimulation for oocyte and embryo cryopreservation is the standard of care for fertility preservation in young breast cancer patients before gonadotoxic chemotherapy. The procedure should be started as soon as possible to avoid delay of treatment; thus, it is often performed concomitantly with tumor staging assessments. However, questions remain regarding the potential negative impact on oocyte quality that may occur due to exposure to scattered ionizing radiation from imaging techniques when staging assessment is conducted at the same time as ovarian stimulation. METHODS: We conducted a retrospective study on all breast cancer patients who performed ovarian stimulation for fertility preservation at our center between November 2012 and May 2020. RESULTS: Gynecologic and oncological characteristics were similar between patients exposed (n = 14) or not (n = 60) to ionizing radiation. Exposed patients started the ovarian stimulation sooner after diagnosis than non-exposed patients (11.5 vs 28 days, respectively, P < 0.01). Cycle parameters, including the median number of oocytes collected (10.5 vs 7, P = 0.16), maturation rates (92.5% vs 85.7%, P = 0.54), and fertilization rates (62.2% vs 65.4%, P = 0.70), were similar between groups. CONCLUSION: This study shows that scattered ionizing radiation due to staging assessment appears to be safe without compromising follicular growth and maturation. Larger studies on fertility and obstetrical outcomes are needed to confirm these preliminary data.

Fertility, sexuality and cancer in young adult women.

PURPOSE OF REVIEW: To provide an up-to-date overview on indications, efficacy and safety of the existing fertility preservation strategies as well as on the features and management of sexual dysfunction in young adult women with newly diagnosed cancer. RECENT FINDINGS: Because of the improved life expectancy of cancer survivors, a growing attention should be given to the side effects of anticancer treatments. Among young cancer patients, risk of infertility and sexual dysfunction are of great concern. SUMMARY: As advocated by guidelines, patients need to be thoroughly informed of potential side effects of treatment before starting them. On this regard, efforts should be made to improve the counseling of young adult patients around fertility and sexuality. Fertility preservation strategies should be properly and extensively explained to all young patients, weighting the pros and cons to choose the more appropriate options for each situation. In addition, discussing sexual dysfunction and delivering sexual rehabilitation for cancer survivors not only allows for renewal of sexual function but can also promote increased quality of life and help women create a new and satisfying chapter in their life for many years after cancer.

Challenges of fertility preservation in non-oncological diseases.

Clinicians should provide fertility counseling to all patients receiving gonadotoxic treatment. International scientific societies have mainly focused on oncological patients, and fewer efforts have been made to apply these recommendations to women diagnosed with benign disease (eg benign hematological diseases, autoimmune diseases, and gynecological or genetic disorders). However, these indications account for 8%-13% of the demand for fertility preservation. The risk of premature ovarian failure due to treatment, or to the disease itself, can be considered fairly high for many young women. Counseling and adequate management of these women require particular attention due to the severe health conditions that are associated with some of these diseases. In this review, we address specific issues related to providing adequate fertility counseling and management for women who have been diagnosed with the major non-oncological indications, based on the literature and on our clinical experience.

Intra- and Inter-Rater Agreement Describing Myometrial Lesions Using Morphologic Uterus Sonographic Assessment: A Pilot Study.

OBJECTIVES: To evaluate the intra- and inter-rater agreement for myometrial lesions using Morphologic Uterus Sonographic Assessment terminology. METHODS: Thirteen raters with high (n = 6) or medium experience (n = 7) assessed 30 3-dimensional ultrasound clips with (n = 20) and without (n = 10) benign myometrial lesions. Myometrial lesions were reported as poorly or well defined and then systematically evaluated for the presence of individual features. The clips were blindly assessed twice (at a 2-month interval). Intra- and inter-rater agreements were calculated with κ statistics. RESULTS: The reporting of poorly defined lesions reached moderate intra-rater agreement (κ = 0.49 [high experience] and 0.47 [medium experience]) and poor inter-rater agreement (κ = 0.39 [high experience] and 0.25 [medium experience]). The reporting of well-defined lesions reached good to very good intra-rater agreement (κ = 0.73 [high experience] and 0.82 [medium experience]) and good inter-rater agreement (κ = 0.75 [high experience] and 0.63 [medium experience]). Most individual features associated with ill-defined lesions reached moderate intra- and inter-rater agreement among highly experienced raters (κ = 0.41-0.60). The least reproducible features were myometrial cysts, hyperechoic islands, subendometrial lines and buds, and translesional flow (κ = 0.11-0.34). Most individual features associated with well-defined lesions reached moderate to good intra- and inter-rater agreement among all observers (κ = 0.41-0.80). The least reproducible features were a serosal contour, asymmetry, a hyperechoic rim, and fan-shaped shadows (κ = 0.00-0.35). CONCLUSIONS: The reporting of well-defined lesions showed excellent agreement, whereas the agreement for poorly defined lesions was low, even among highly experienced raters. The agreement on identifying individual features varied, especially for features associated with ill-defined lesions. Guidelines on minimum requirements for features associated with ill-defined lesions to be interpreted as poorly defined lesions may improve agreement.

Impact of Breast Cancer and Germline BRCA Pathogenic Variants on Fertility Preservation in Young Women.

BACKGROUND: Several studies have suggested that breast cancer (BC) and germline BRCA pathogenic variants (gBRCA PVs) could have a deleterious impact on ovarian reserve. Nevertheless, data are limited and mixed. Our objective was to evaluate the performance of fertility preservation (FP) in terms of the number of collected mature oocytes after ovarian stimulation (OS) in young women carrying a gBRCA PV, associated or not with BC. METHODS: We conducted a retrospective monocentric study at HUB-Hôpital Erasme in Brussels. All women aged between 18 and 41 years diagnosed with invasive non-metastatic BC and/or gBRCA PV carriers who underwent OS for FP or preimplantation genetic testing for monogenic disorder (PGT-M) between November 2012 and October 2021 were included. Three groups were compared: BC patients without a gBRCA PV, BC patients with a gBRCA PV, and healthy gBRCA PV carriers. Ovarian reserve was evaluated based on the efficacy of OS and AMH levels. RESULTS: A total of 85 patients underwent 100 cycles. The mean age (32.2 ± 3.9 years; p = 0.61) and median AMH level (1.9 [0.2-13] µg/L; p = 0.22) were similar between groups. Correlations between the number of mature oocytes and AMH level (p < 0.001) and between AMH and age (p < 0.001) were observed. No differences in the number of retrieved mature oocytes were observed between groups (p = 0.41), or for other OS parameters. CONCLUSION: Neither BC nor a gBRCA PV significantly affects ovarian reserve and FP efficacy in terms of the number of mature oocytes retrieved.

The Role of Cyclin-Dependent Kinases (CDK) 4/6 in the Ovarian Tissue and the Possible Effects of Their Exogenous Inhibition.

The combination of cyclin-dependent kinase (CDK) 4/6 inhibitors with endocrine therapy is the standard treatment for patients with HR+/HER2- advanced breast cancer. Recently, this combination has also entered the early setting as an adjuvant treatment in patients with HR+/HER2- disease at a high risk of disease recurrence following (neo)adjuvant chemotherapy. Despite their current use in clinical practice, limited data on the potential gonadotoxicity of CDK4/6 inhibitors are available. Hence, fully informed treatment decision making by premenopausal patients concerned about the potential development of premature ovarian insufficiency and infertility with the proposed therapy remains difficult. The cell cycle progression of granulosa and cumulus cells is a critical process for ovarian function, especially for ensuring proper follicular growth and acquiring competence. Due to the pharmacological properties of CDK4/6 inhibitors, there could be a potentially negative impact on ovarian function and fertility in women of reproductive age. This review aims to summarize the role of the cyclin D-CDK4 and CDK6 complexes in the ovary and the potential impact of CDK4/6 inhibition on its physiological processes.
