Low-grade inflammation is negatively associated with live birth in women undergoing IVF.

Research Question: Is low-grade inflammation, detected by C-reactive protein (CRP), a marker of IVF outcome addressing both blastocyst quality and pregnancy outcome?

Design: This sub-study of a multicentre randomized controlled trial included 440 women undergoing IVF treatment with a gonadotrophin-releasing hormone (GnRH) antagonist protocol. Serum CRP was measured on cycle day 2-3 (baseline) and on the day of ovulation triggering. The association between CRP concentrations and reproductive outcomes (number of retrieved oocytes, number of good-quality blastocysts, pregnancy, pregnancy loss and live birth), were analysed, adjusting for relevant confounders.

RUBIC (ReproUnion Biobank and Infertility Cohort): A binational clinical foundation to study risk factors, life course, and treatment of infertility and infertility-related morbidity.

Background: Infertility affects 15%-25% of all couples during their reproductive life span. It is a significant societal and public health problem with potential psychological, social, and economic consequences. Furthermore, infertility has been linked to adverse long-term health outcomes.

Stress and depression among women and men who have experienced recurrent pregnancy loss: focusing on both sexes.

Research Question: Are women and men suffering from recurrent pregnancy loss (RPL) more affected by psychological stress and depression than the general population?

Design: Cross-sectional study investigating the prevalence of stress and depression in women and men with RPL seen in the Danish national RPL Unit. Data were collected between 2015-2018. All newly referred couples were asked to complete the Major Depression Index (MDI) and Cohen's Perceived Stress Scale (PSS).

Ovarian reserve markers and endocrine profile during oral contraception: Is there a link between the degree of ovarian suppression and AMH?

The ovarian reserve markers anti-Müllerian hormone (AMH) and antral follicle count (AFC) are suppressed in varying degree during the use of combined oral contraceptives (COC). Further, long-term use of COC can mask a condition of premature ovarian insufficiency. A desirable clinical tool that could distinguish true low ovarian reserve markers from COC-induced low levels use of COC is warranted.

Ovarian reserve markers in women using various hormonal contraceptives.

The aim of the study was to assess whether the ovarian reserve markers anti-Müllerian hormone (AMH) and antral follicle count (AFC) were lower among women using the progestin-only pill (POP) or levonorgestrel-releasing intrauterine system (LNG-IUS) and similar to the decrease observed in combined oral contraceptive (COC) pill users. This retrospective study comprised 565 hormonal contraceptive users (COC, POP, LNG-IUS or contraceptive vaginal ring) and 983 non-hormonal contraceptive users, who were seen in two Danish fertility assessment and counselling clinics between 2015 and 2019. Adjusted multiple regression analysis was used to examine the differences in AMH and AFC between hormonal and non-hormonal contraceptive users.

Ovarian reserve markers after discontinuing long-term use of combined oral contraceptives.

Research Question: How early do the ovarian reserve markers anti-Müllerian hormone (AMH) and antral follicle count (AFC) normalize after discontinuation of the long-term use of combined oral contraceptives (COC).

Design: This was a prospective cohort study of 68 women with a history of long-term COC use. Serum AMH concentrations, ovarian volume and AFC were measured during COC use and serially in a 4-month period after discontinuing COC: 1 and 2 weeks after discontinuation, and on cycle day 2-5 during three consecutive menstrual cycles.

Biopsying, fragmentation and autotransplantation of fresh ovarian cortical tissue in infertile women with diminished ovarian reserve.

Study Question: Can ovarian biopsying per se and/or autotransplantation of fragmented ovarian cortical tissue activate dormant follicles and increase the number of recruitable follicles for IVF/ICSI in women with diminished ovarian reserve (DOR)?

Summary Answer: Ovarian biopsying followed by immediate autotransplantation of fragmented cortical tissue failed to increase the number of recruitable follicles for IVF/ICSI 10 weeks after the procedure either at the graft site or in the biopsied ovary, but 12 of the 20 women subsequently had a clinical pregnancy during the 1-year follow-up.

What Is Known Already: Infertile women with DOR constitute a group of patients with poor reproductive outcome mainly due to the low number of mature oocytes available for IVF/ICSI. Recent studies have shown that in vitro activation of residual dormant follicles by both chemical treatment and tissue fragmentation has resulted in return of menstrual cycles and pregnancies in a fraction of amenorrhoeic women with premature ovarian insufficiency.

Concerns on future fertility among users and past-users of combined oral contraceptives: a questionnaire survey.

The combined oral contraceptive pill is the most preferred contraceptive method worldwide. Despite high life-time prevalence of infertility of 16-26%, scarce data about concerns of future fertility among COC users are available. We aimed to study whether COC usage induces concerns about fertility.
