Predicting tubal factor infertility by using markers of humoral and cell-mediated immune response against Chlamydia trachomatis

PROBLEM

The accuracy of Chlamydia trachomatis antibody test in predicting tubal factor infertility (TFI) is limited, and more accurate methods are needed. Cell-mediated immune response (CMI) is crucial in the resolution of pathogen, but it may play an important role in the pathogenesis of C trachomatis-associated tubal damage. We studied whether combining the markers of C trachomatis-induced CMI to humoral immune response improves the accuracy of serology in TFI prediction.

METHOD OF STUDY

Our prospective study consists of 258 subfertile women, of whom 22 (8.5%) had TFI. Women with other causes for subfertility served as a reference group. Serum C trachomatis major outer membrane protein (MOMP) and chlamydial heat-shock protein 60 (cHSP60) IgG antibodies were measured by ELISA. CMI was studied by lymphocyte proliferation assay in vitro.

RESULTS

Serological markers were more prevalent in women with TFI than in other subfertile women (40.9% vs 12.3% for MOMP IgG and 27.3% vs 10.2% for cHSP60 IgG). The best test combination for TFI was C. trachomatis MOMP and cHSP60 antibody with an accuracy of 90.3%, sensitivity of 22.7% and specificity of 96.6%. Positive post-test probability of this combination was 54.2%, and negative post-test probability was 12.4%. Adding of the markers of CMI did not significantly improve the accuracy of serology in TFI prediction.

CONCLUSION

The accuracy of TFI prediction increases when the combination of C trachomatis MOMP and cHSP60 antibody tests is used. C trachomatis-induced CMI was common in our study population, but the markers of CMI did not predict TFI.

A Nationwide Cohort Study on the risk of non-gynecological cancers in women with surgically verified endometriosis

We assessed the association of surgically verified endometriosis and risk of non-gynecological cancers according to the type of endometriosis (i.e., ovarian, peritoneal and deep infiltrating endometriosis). All diagnoses of endometriosis combined with relevant procedural codes were identified from the Finnish Hospital Discharge Register 1987-2012. Non-gynecological cancers diagnosed after the endometriosis diagnosis were obtained from the Finnish Cancer Registry. The cohort of 49,933 women with surgically verified endometriosis and the sub-cohorts of ovarian (n = 23,210), peritoneal (n = 20,187), and deep infiltrating (n = 2,372) endometriosis were analyzed separately. The endometriosis cohort contributed 838,685 person-years of follow-up and the Finnish female population served as the reference cohort. The standardized incidence ratio (SIR) and 95% confidence interval (95%CI) was calculated for each cancer separately. The follow-up ended at emigration, death or on the 31st of December 2014. The non-gynecological cancer risk was not increased among women with endometriosis (SIR 1.03, 95%CI 0.98-1.08). Endometriosis was associated with an increased risk of thyroid cancer in the entire cohort (SIR 1.43, 95%CI 1.23-1.64) and in the sub-cohorts of ovarian and peritoneal endometriosis. We found a decreased risk of mouth and pharynx cancer (SIR 0.60, 95%CI 0.41-0.80), and of pancreatic cancer (SIR 0.76, 95%CI 0.58-0.96). The incidence of basal cell carcinoma was elevated in the entire cohort (SIR 1.18, 95%CI 1.10-1.25) and in the sub-cohorts of ovarian and peritoneal endometriosis. In conclusion, women with surgically verified endometriosis have an altered risk of only few non-gynecological cancers.

Prevention of gestational diabetes with a prepregnancy lifestyle intervention - findings from a randomized controlled trial

Purpose

Lifestyle intervention studies performed during pregnancy have shown inconsistent results in relation to prevention of gestational diabetes mellitus (GDM). Therefore, the aim of this study was to assess the effect of an intervention initiated already before pregnancy in prevention of GDM in high-risk women.

Patients and methods

A randomized controlled trial was conducted in four Finnish maternity hospitals between the years 2008 and 2014. Altogether 228 high-risk women planning pregnancy were randomized to an intervention (n=116) or a control group (n=112). The risk factors were body mass index ≥30 kg/m² (n=46), prior GDM (n=120), or both (n=62), without manifest diabetes at study inclusion. Trained study nurses provided individualized lifestyle counseling every 3 months in addition to a group session with a dietician. The control group received standard antenatal care. GDM was defined as one or more pathological glucose values in a 75 g 2-hour oral glucose tolerance test, performed between 12 and 16 weeks of gestation and if normal repeated between 24 and 28 weeks of gestation.

Results

Within 12 months, 67% of the women (n=72) in the intervention group and 63% of the women (n=71) in the control group (p=0.84) became pregnant. The cumulative incidence of GDM among the women available for the final analyses was 60% (n=39/65) in the intervention group and 54% (n=34/63) in the control group (p=0.49). GDM was diagnosed already before 20 weeks of gestation in 60% (n=44/73) of the cases.

Conclusion

The preconceptional lifestyle intervention applied in the present study did not reduce the incidence of GDM.

The mental health of mothers and fathers during pregnancy and early parenthood after successful oocyte donation treatment: A nested case-control study

INTRODUCTION

The aim of this study was to compare the mental health problems between parents after oocyte donation treatment, after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with own gametes and after naturally conceiving (NC).

MATERIAL AND METHODS

This is a prospective, longitudinal questionnaire study. The study group consisted of 26 oocyte donation mothers and their matched IVF/ICSI (n = 52) and NC (n = 52) controls. Matching was performed according to mother's age, parity, type of pregnancy, and number of returned questionnaires. The parents filled-in the General Health Questionnaire (GHQ-36) at gestational weeks 18-20 (T1), and at 2 months (T2) and 12 months (T3) after the childbirth.

RESULTS

Full response rate (T1-T3) for oocyte donation mothers was 76.9% and for oocyte donation fathers was 73.1%. At T1, no significant differences were found between groups in depression, anxiety, sleeping difficulties, or social dysfunction, but they differed at T2 and T3 in anxiety (T2, P = .02; T3, P = .01), in sleeping difficulties (T2, P = .02; T3, P = .04) and in social dysfunction (T2, P = .01; T3, P = .04). Oocyte donation mothers showed less anxiety than NC mothers (T2, T3), and fewer sleeping difficulties and less social dysfunction than IVF/ICSI (T2, T3) and NC mothers (T2). Mental health problems of oocyte donation fathers did not differ from those of IVF/ICSI and NC control fathers at T1-T3.

CONCLUSIONS

Oocyte donation mothers showed fewer mental health symptoms in early parenthood compared with IVF/ICSI and NC mothers. No differences were found among mothers during pregnancy and among fathers at any time point.

rs10732516 polymorphism at the IGF2/H19 locus associates with genotype-specific effects on placental DNA methylation and birth weight of newborns conceived by assisted reproductive technology

Background

Assisted reproductive technology (ART) has been associated with low birth weight of fresh embryo transfer (FRESH) derived and increased birth weight of frozen embryo transfer (FET)-derived newborns. Owing to that, we focused on imprinted insulin-like growth factor 2 (IGF2)/H19 locus known to be important for normal growth. This locus is regulated by H19 imprinting control region (ICR) with seven binding sites for the methylation-sensitive zinc finger regulatory protein (CTCF). A polymorphism rs10732516 G/A in the sixth binding site for CTCF, associates with a genotype-specific trend to the DNA methylation. Due to this association, 62 couples with singleton pregnancies derived from FRESH (44 IVF/18 ICSI), 24 couples from FET (15 IVF/9 ICSI), and 157 couples with spontaneously conceived pregnancies as controls were recruited in Finland and Estonia for genotype-specific examination. DNA methylation levels at the H19 ICR, H19 DMR, and long interspersed nuclear elements in placental tissue were explored by MassARRAY EpiTYPER (n = 122). Allele-specific changes in the methylation level of H19 ICR in placental tissue (n = 26) and white blood cells (WBC, n = 8) were examined by bisulfite sequencing. Newborns' (n = 243) anthropometrics was analyzed by using international growth standards.

Results

A consistent trend of genotype-specific decreased methylation level was observed in paternal allele of rs10732516 paternal A/maternal G genotype, but not in paternal G/maternal A genotype, at H19 ICR in ART placentas. This hypomethylation was not detected in WBCs. Also genotype-specific differences in FRESH-derived newborns' birth weight and head circumference were observed (P = 0.04, P = 0.004, respectively): FRESH-derived newborns with G/G genotype were heavier (P = 0.04) and had larger head circumference (P = 0.002) compared to newborns with A/A genotype. Also, the placental weight and birth weight of controls, FRESH- and FET-derived newborns differed significantly in rs10732516 A/A genotype (P = 0.024, P = 0.006, respectively): the placentas and newborns of FET-derived pregnancies were heavier compared to FRESH-derived pregnancies (P = 0.02, P = 0.004, respectively).

Conclusions

The observed DNA methylation changes together with the phenotypic findings suggest that rs10732516 polymorphism associates with the effects of ART in a parent-of-origin manner. Therefore, this polymorphism should be considered when the effects of environmental factors on embryonic development are studied.

Heterogeneity of gestational diabetes (GDM) and long-term risk of diabetes and metabolic syndrome: findings from the RADIEL study follow-up

AIMS

To assess the metabolic health of obese and non-obese women at high GDM risk 5 years postpartum.

METHODS

This is a secondary analysis of the 5-year follow-up of the RADIEL GDM prevention study including 333 women at high GDM risk (BMI ≥ 30 kg/m² and/or previous GDM). Five years postpartum metabolic health was assessed including anthropometric measurements, oral glucose tolerance test, lipid metabolism, and body composition as well as medical history questionnaires. For the analysis, we divided the women into four groups based on parity, BMI, and previous history of GDM.

RESULTS

Five years postpartum impaired glucose regulation (IFG, IGT, or diabetes) was diagnosed in 15% of the women; 3.6% had type 2 diabetes. The highest prevalence was observed among obese women with a history of GDM (26%), and the lowest prevalence (8%) among primiparous obese women (p = 0.021). At follow-up 25-39% of the obese women fulfilled the diagnostic criteria for the metabolic syndrome, in the non-obese group 11% (p < 0.001). This was associated with body fat percentage. The non-obese group, however, faced metabolic disturbances (IFG, IGT, diabetes, or metabolic syndrome) at a significantly lower BMI (p < 0.001). Among women who were non-obese before pregnancy, 5 years postpartum, the obesity prevalence based on BMI was 14% and based on body fat percentage 58%.

CONCLUSIONS

The prevalence of impaired glucose regulation and metabolic syndrome is high 5 years postpartum among women at high risk of GDM. There are high-risk women also among the non-obese, who develop metabolic derangements already at a lower BMI.

Chlamydia trachomatis-induced cell-mediated and humoral immune response in women with unexplained infertility

PROBLEM

What is the role of past Chlamydia trachomatis infection in unexplained infertility?

METHOD OF STUDY

This is a prospective study of the impact of past C. trachomatis infection on pregnancy rates in 96 women with unexplained infertility. Both humoral and cell-mediated immune responses (CMI) against C. trachomatis were studied. Serum C. trachomatis IgG antibodies were analyzed using major outer membrane protein (MOMP) peptide-based ELISA. CMI was studied by lymphocyte proliferation (LP) assay in vitro. Data on given fertility treatment, time to pregnancy, and pregnancy outcome were collected.

RESULTS

Altogether, 11.5% of the 96 women had C. trachomatis IgG antibodies. LP response to C. trachomatis was positive in 62.9% women. The overall pregnancy rate or live birth rate did not differ by the presence of antichlamydial antibodies or CMI against C. trachomatis. Time to spontaneous pregnancy was longer among C. trachomatis sero-positive women than among sero-negative women (2.9 years vs 2.0 years, P = .03).

CONCLUSION

Past chlamydial infection does not play a major role in unexplained infertility. Women with unexplained infertility and positive immune response to C. trachomatis do not have reduced pregnancy rates, but time to spontaneous pregnancy is longer among C. trachomatis IgG sero-positive women than among sero-negative women.

Trends over time in congenital malformations in live-born children conceived after assisted reproductive technology

INTRODUCTION

Children born after assisted reproductive technology, particularly singletons, have been shown to have an increased risk of congenital malformations compared with children born after spontaneous conception. We wished to study whether there has been a change in the past 20 years in the risk of major congenital malformations in children conceived after assisted reproductive technology compared with children spontaneously conceived.

MATERIAL AND METHODS

Population-based cohort study including 90 201 assisted reproductive technology children and 482 552 children spontaneously conceived, born in Denmark, Finland, Norway and Sweden. Both singletons and twins born after in vitro fertilization, intracytoplasmatic sperm injection and frozen embryo transfer were included. Data on children were taken from when the national Nordic assisted reproductive technology registries were established until 2007. Multiple logistic regression analyses were used to estimate the risks and adjusted odds ratios for congenital malformations in four time periods: 1988-1992, 1993-1997, 1998-2002 and 2003-2007. Only major malformations were included.

RESULTS

The absolute risk for singletons of being born with a major malformation was 3.4% among assisted reproductive technology children vs. 2.9% among children spontaneously conceived during the study period. The relative risk of being born with a major congenital malformation between all assisted reproductive technology children and children spontaneously conceived remained similar through all four time periods (p = 0.39). However, we found that over time the number of children diagnosed with a major malformation increased in both groups across all four time periods.

CONCLUSION

When comparing children conceived after assisted reproductive technology and spontaneously conceived, the relative risk of being born with a major congenital malformation did not change during the study period.

Effects of a Lifestyle Intervention During Pregnancy and First Postpartum Year: Findings From the RADIEL Study

CONTEXT

Women with a history of gestational diabetes (GDM) have a sevenfold risk of developing type 2 diabetes.

OBJECTIVE

To assess the effects of a lifestyle intervention during pregnancy and first postpartum year on glucose regulation, weight retention, and metabolic characteristics among women at high GDM risk.

DESIGN

In the Finnish Gestational Diabetes Prevention study, trained study nurses provided lifestyle counseling in each trimester and 6 weeks, 6 months, and 12 months postpartum.

SETTING

Three maternity hospitals in the Helsinki area and one in Lappeenranta.

PATIENTS

In total, 269 women with previous GDM and/or a prepregnancy body mass index ≥30 kg/m2 were enrolled before 20 gestational weeks and allocated to either a control or an intervention group. This study includes the 200 participants who attended study visits 6 weeks and/or 12 months postpartum.

INTERVENTION

The lifestyle intervention followed Nordic diet recommendations and at least 150 minutes of moderate exercise was recommended weekly.

MAIN OUTCOME MEASURE

The incidence of impaired glucose regulation (impaired fasting glucose, impaired glucose tolerance, or type 2 diabetes) during the first postpartum year.

RESULTS

Impaired glucose regulation was present in 13.3% of the women in the control and in 2.7% in the intervention group [age-adjusted odds ratio, 0.18 (95% confidence interval, 0.05 to 0.65), P = 0.009] during the first postpartum year. There were no differences between the groups in weight retention, physical activity, or diet at 12 months postpartum.

CONCLUSIONS

A lifestyle intervention during pregnancy and the first postpartum year successfully reduced the incidence of postpartum impairment in glucose regulation.

Termination of pregnancy and sterilisation in women with childhood-onset type 1 diabetes

AIMS/HYPOTHESIS

The aim of this study was to explore the association between type 1 diabetes and reproductive health indicators in women, focusing on termination of pregnancy and sterilisation.

METHODS

We conducted a registry-based cohort study involving 2281 women with childhood-onset type 1 diabetes, matched for age and birthplace with women without diabetes: two control participants for each woman with diabetes. We compared the frequencies of termination of pregnancy and sterilisation over a 25 year period between women with type 1 diabetes and women without, and estimated standardised incidence ratios (SIRs). Smoothed age and period effects in the incidence of termination of pregnancy or sterilisation were tested statistically.

RESULTS

There were more terminations of pregnancy (SIR 1.67; 95% CI 1.51, 1.86) and sterilisations (SIR 1.69; 95% CI 1.56, 1.83) in women with diabetes than in control women. During recent years, sterilisations in women with diabetes have decreased and the difference compared with control women has vanished. The indications for both procedures showed a statistically highly significant difference: maternal medical indications were almost absent (< 1%) in procedures among control women, but comprised 23.6% of terminations of pregnancy and 22.9% of sterilisations in women with diabetes.

CONCLUSIONS/INTERPRETATION

The indications for termination of pregnancy and sterilisation are different in women with diabetes compared with other women. Pregnancies in women with type 1 diabetes are still terminated more often than in women without diabetes, but the difference in sterilisation rates has disappeared during recent years.

Trends in the incidence rate, type and treatment of surgically verified endometriosis - a nationwide cohort study

INTRODUCTION

To study the trends in incidence rate, type and surgical treatment, and patient characteristics of surgically verified endometriosis during 1987-2012.

MATERIAL AND METHODS

This is a register-based cohort study. We identified women receiving their first diagnosis of endometriosis in surgery from the Finnish Hospital Discharge Register (FHDR). Quality of the FHDR records was assessed bidirectionally. The age-standardized incidence rates of the first surgically verified endometriosis was assessed by calendar year.

RESULTS

The cohort comprises 49 956 women. The quality assessment suggested the FHDR data to be of good quality. The most common diagnosis, ovarian endometriosis (46%), was associated with highest median age 38.5 years (interquartile range 31.0-44.8) and the second most common diagnosis, peritoneal endometriosis (40%), with median age 34.9 years (28.6-41.7). Between 1987 and 2012, a decrease was observed in the median age, from 38.8 (32.3-43.6) to 34.0 (28.9-41.0) years, and in the age-standardized incidence rate from 116 [95% confidence interval (CI) 112-121] to 45 (42-48) per 100 000 women. The proportion of hysterectomy as a first surgical treatment decreased from 38 to 19%, whereas that of laparoscopy increased from 42 to 73% when comparing 1987-1995 with 1996-2012.

CONCLUSIONS

This nationwide cohort of surgically verified endometriosis showed a decrease in the incidence rate and in the patient age at the time of first diagnosis, even though the proportion of laparoscopy has increased. The number of hysterectomies has decreased. These changes are likely to reflect the evolving diagnostics, increasing awareness of endometriosis, and effective use of medical treatment before surgery.

Fertility treatments among female cancer survivors giving birth - a Finnish register-based study

BACKGROUND

Long-term survival rates for most types of childhood cancers have improved dramatically over the past decades. However, because of advances in multimodality treatments, cancer survivors nowadays more often face long-term complications, including diminished gonadal and reproductive function. The aim of this study was to identify whether the use of fertility treatments among early onset (0-34 years) cancer survivors giving birth differed from that among siblings giving birth and to identify the subgroups of cancer survivors that were most likely to require fertility treatments.

MATERIAL AND METHODS

Nationwide cancer and birth registries were merged to identify 1974 post-diagnosis deliveries of cancer survivors and 6107 deliveries of female siblings in 2004-2013. Unconditional multivariate logistic regression models were used to estimate the risk for different fertility treatments namely assisted reproductive technology, intrauterine insemination and ovulation induction. We adjusted for maternal age, year of delivery, parity and smoking.

RESULTS

We found overall significantly increased odds for use of any fertility treatments in survivors compared to siblings (OR 1.84, 95% CI 1.18-2.86). As time from cancer treatment increased, the odds for need of fertility treatments increased, being highest at 11 to 15 years post cancer treatment (OR 2.88, 95% CI 1.13-7.30). Survivors diagnosed at ages 25-34 years had the highest odds for use of fertility treatments compared to siblings (OR 2.31, 95% CI 1.01-5.32).

CONCLUSIONS

Our study supports previous findings indicating that cancer survivors have an increased risk for subfertility. Survivors diagnosed in their childhood had the lowest risk for fertility treatment and seemed to get pregnant with less extensive fertility treatments than survivors diagnosed as adults. Time elapsed from cancer treatment played a central role, increasing the need for fertility treatments compared to siblings, suggesting that cancer therapies might lead to diminished ovarian reserve.

Cardiorespiratory fitness and health-related quality of life in women at risk for gestational diabetes

This study examined the associations of cardiorespiratory fitness (CRF) and leisure-time physical activity (LTPA) with health-related quality of life (HRQoL) in women at risk for gestational diabetes mellitus (GDM). The participants were 39 women planning pregnancy with a history of GDM and/or BMI >29 kg/m² . We assessed CRF by measuring maximal oxygen consumption (VO_2max ) during incremental cycle ergometer exercise until voluntary fatigue. LTPA was self-reported, and HRQoL assessed with the SF-36 Health Survey (SF-36). The mean (SD) VO_2max was 27 (6) mL·kg^-1 ·min^-1 , and the mean LTPA was 2.6 (1.7) h/wk. After controlling for BMI, VO_2max was positively associated with the SF-36 General Health scale (β 1.27, 95% CI: 0.09, 2.44, P=.035) and the Physical Component Summary (β 0.48, 95% CI: 0.14, 0.82, P=.007). The General Health scale (P=.023) and the Physical Component Summary (P=.011) differed even between those with very poor and poor CRF. After controlling for BMI, LTPA was positively associated with the SF-36 Physical Functioning scale (r_s =.34, P=.039), the General Health scale (β 3.74, 95% CI: 0.64, 6.84, P=.020), and the Physical Component Summary (β 1.13 95% CI: 0.19, 2.06, P=.020). To conclude, CRF and LTPA were positively associated with perceived general health and physical well-being in women planning pregnancy and at risk for GDM. Even a slightly better CRF would be beneficial for well-being among women with low levels of CRF.

From early family systems to internalizing symptoms: The role of emotion regulation and peer relations

Research has demonstrated the importance of early family characteristics, such as the quality of caregiving, on children's later mental health. Information is, however, needed about the role of more holistic family systems and specific child-related socioemotional mechanisms. In this study, we conceptualize families as dynamic family system types, consisting of both marital and parenting trajectories over the transition to parenthood. First, we examine how early family system types predict children's anxiety, depression, peer exclusion, and emotion regulation. Second, we test whether couples' infertility history and other family related contextual factors moderate the effects of family system types on child outcomes. Third, we test whether children's emotion regulation and peer exclusion mediate the effects of family system types on anxiety and depression. The participants were 452 families representing cohesive, distant, authoritative, enmeshed, and discrepant family types, identified on the basis of relationship autonomy and intimacy from pregnancy to the child's age of 2 and 12 months. Children's anxiety, depression, emotion regulation, and peer exclusion were assessed at the age of 7-8 years. Structural equation modeling showed that distant, enmeshed, and discrepant families similarly predicted children's heightened anxiety and depression. Infertility history, parental education, and parity moderated the associations between certain family system types and child outcomes. Finally, emotion regulation, but not peer exclusion, was a common mediating mechanism between distant and enmeshed families and children's depression. The results emphasize the importance of early family environments on children's emotion regulation development and internalizing psychopathology. (PsycINFO Database Record

Selective progesterone receptor modulators: new possibilities for gynecologic hormone therapy

Progesterone regulates several female reproductive functions. Progesterone and synthetic progestins derived from it have long been utilized in gynecology. The effects of these steroids in target cells are mediated via progesterone receptors, Progesterone receptors are also the target of action of selective progesterone receptor modulators. Of the molecules of this newer group of drugs, two are presently in clinical use. Mifepristone is used in nonsurgical abortion, in softening of the cervix before surgical abortion, and in the induction of labor in cases of intrauterine death. The indications of ulipristal acetate are postcoital contraception and treatment of uterine myomas and the resulting symptoms.

Early family system types predict children’s emotional attention biases at school age

The family environment shapes children’s social information processing and emotion regulation. Yet, the long-term effects of early family systems have rarely been studied. This study investigated how family system types predict children’s attentional biases toward facial expressions at the age of 10 years. The participants were 79 children from Cohesive, Disengaged, Enmeshed, and Authoritarian family types based on marital and parental relationship trajectories from pregnancy to the age of 12 months. A dot-probe task was used to assess children’s emotional attention biases toward threatening (angry) and affiliative (happy) faces at the early (500 ms) and late (1250 ms) stages of processing. Situational priming was applied to activate children’s sense of danger or safety. Results showed that children from Cohesive families had an early-stage attentional bias toward threat, whereas children from Enmeshed families had a late-stage bias toward threat. Children from Disengaged families had an early-stage attentional bias toward threat, but showed in addition a late-stage bias away from emotional faces (i.e., both angry and happy). Children from Authoritarian families, in turn, showed a late-stage attentional bias toward emotional faces. Situational priming did not moderate the effects of family system types on children’s attentional biases. The findings confirm the influence of early family systems on the attentional biases, suggesting differences in the emotion regulation strategies children have developed to adapt to their family environments.

Ovarian tissue cryopreservation and transplantation among alternatives for fertility preservation in the Nordic countries - compilation of 20 years of multicenter experience

Introduction

The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries.

Material and methods

A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard procedures for ovarian tissue cryopreservation and oocyte cryopreservation and reproductive outcomes following ovarian tissue transplantation.

Results

Among the Nordic countries, Denmark and Norway practice ovarian tissue cryopreservation as a clinical treatment (822 and 164 cases, respectively) and their programs are centralized. In Sweden (457 cases), ovarian tissue cryopreservation is practiced at five of six centers and in Finland at all five centers (145 cases). Nearly all considered ovarian tissue cryopreservation to be experimental. In Iceland, embryo cryopreservation is the only option for fertility preservation. Most centers use slow‐freezing methods for ovarian tissue cryopreservation. Most patients selected for ovarian tissue cryopreservation were newly diagnosed with cancer and the tissue was predominantly retrieved laparoscopically by unilateral oophorectomy. Only minor complications were reported. In total, 46 women have undergone ovarian tissue transplantation aiming at recovering fertility, 17 healthy children have been born and several additional pregnancies are currently ongoing. Whenever patients’ clinical condition is permissive, oocyte cryopreservation after hormonal stimulation is preferred for fertility preservation. Between 2012 and 2014, a smaller proportion of females have undergone fertility preservation in the Nordic centers, in comparison to males (1:3).

Conclusions

Overall, ovarian tissue cryopreservation was reported to be safe. Slow freezing methods are still preferred. Promising results of recovery of fertility have been reported in Nordic countries that have initiated ovarian tissue transplantation procedures.

Paternal mental health trajectory classes and early fathering experiences

A father’s mental health is important for family well-being, but research is scarce on paternal symptoms during the transition to fatherhood. This study identified fathers’ latent mental health trajectory classes from the pre- to postnatal period and examined their associations with early fathering experiences. It further analysed, whether a family’s infertility history was associated with mental health trajectory classes and moderated their effects on fathering experiences. Finnish fathers ( N = 773) reported psychological distress (General Health Questionnaire; GHQ-36) and depressive symptoms (Beck Depression Inventory; BDI-13) in pregnancy (T1), and at 2 months (T2) and 12 months (T3) postpartum. They further reported their fathering experience (Parenting Stress Index; PSI-36) at T2 and T3. Results revealed five paternal mental health trajectory classes, differing in timing and course of symptoms across the pre- and postpartum: stable low (79%) and moderate increasing (9%) levels of symptoms, and prenatal (5%), early fatherhood (3%) and heterogeneous high levels of (4%) problems. The trajectory classes were associated with fathering experiences within parental, interactive and child domains, across the child’s first year. The stable low levels of symptoms-class showed the most positive experiences and the heterogeneous high levels of problems-class the most negative ones; mental health problems in the early fatherhood-class reported negative fathering experience, but only when the child was 2 months old. A family’s infertility history neither showed any significant association with trajectory classes nor moderated their impact on early fathering, supporting the growing evidence that infertility treatments do not place an additional burden on early fatherhood.

Deep infiltrating endometriosis affecting the urinary tract-surgical treatment and fertility outcomes in 2004-2013

Urinary tract endometriosis (UTE) is a rare form of deep infiltrating endometriosis. We studied the operative treatment of UTE and evaluated postoperative recurrences and fertility outcomes. This is a retrospective cohort study of 53 women who underwent operative treatment for UTE in 2004–2013 at Helsinki University Hospital, and were followed-up until the end of 2014. The data were gathered from the hospital’s electronic database. The main outcome measures were complications, reoperations, postoperative pregnancies, and deliveries. Preoperative diagnosis was accurate in 72 % with bladder endometriosis and in 93 % with ureteral disease. Thirty-one (58 %) of the 53 operations were performed via laparoscopy. Postoperative complications requiring re-intervention occurred in five cases (9 %). Five reoperations were performed in four cases due to endometriosis recurrence, only two due to recurrence of UTE (4 %). Twenty-eight women wished for pregnancy; 18 (64 %) of them conceived. Infertility treatment was needed in 20 (71 %) cases. Twelve (75 %) women delivered via cesarean section; intraoperative difficulties occurred in ten (83 %). The complication rate with UTE operations is acceptable and recurrences are rare. Infertility is common, but 57 % of those who wished for a child succeeded. A majority of the deliveries involved unplanned and complicated cesarean section.
