Intravaginal exposure to seminal plasma after ovum pick-up does not increase live birth rates after in vitro fertilization or intracytoplasmic sperm injection treatment: a double-blind, placebo-controlled randomized trial.

Objective: To detect whether intravaginal exposure to prepared seminal plasma led to an absolute increase in live birth rate (LBR) after in vitro fertilization (IVF) by 10% compared with placebo. It has been suggested that intravaginal deposition of seminal plasma after ovum pick-up (OPU) for IVF treatment, increases pregnancy and LBRs.

Design: Double-blind, placebo-controlled prospective study.

Long-term follow-up of mental health and satisfaction in a Swedish sample of sperm and egg donors after open-identity donation.

Research Question: How is the mental health of open-identity gamete donors and their satisfaction with their contributions 14-17 years after acceptance as a donor?

Design: The Swedish Study on Gamete Donation is a longitudinal study comprising women and men who were accepted as donors at seven Swedish university clinics between 2005 and 2008. The latest (fifth) follow-up included 215 open-identity donors (response rate 87%): 123 oocyte donors and 92 sperm donors. The donors answered a questionnaire regarding their perceptions, experiences and expectations after gamete donation 14-17 years previously.

Maternal advanced age, single parenthood, and ART increase the risk of child morbidity up to five years of age.

Background: Advanced maternal age, single status and use of assisted reproductive technology (ART) are increasing in mothers in high-income countries, and all are known risk factors for negative obstetric outcomes. Less is known about their long-term consequences for childhood morbidity. Thus, the aim of this study was to investigate morbidity up to five years of age, in the children of older, single, and/or ART-treated mothers.

Men born small for gestational age or with low birth weight do not improve their rate of reproduction over time: a Swedish population-based study.

Objective: To investigate whether the reduced reproductive rate among men born small for gestational age (SGA) or with low birth weight (LBW) is present after up to 44 years of follow-up.

Design: Population-based register study.

Setting: National registers in Sweden.

Birth characteristics in men with infertility.

Research Question: Are low birth weight, prematurity, being born small for gestational age, or both, associated with a higher risk of male factor infertility in adulthood?

Design: Retrospective study of a clinical sample of 892 men, diagnosed with an infertility factor (male, female, combined or unexplained) together with their female partner at a University Hospital clinic in Sweden between 2005 and 2010. Data on birth weight and gestational age at birth were retrieved from the Swedish Medical Birth Register. The distribution of non-optimal birth characteristics in relation to infertility factor was described.

Mothers who have given birth at an advanced age - health status before and after childbirth.

Women postpone childbirth to an age when morbidity is higher and fertility has decreased and yet the knowledge of mothers' morbidity related to age remains scarce. Swedish national register data from the Medical Birth Register and National Patient Register was used to investigate the incidence of diseases listed in the International Classification of Diseases, version 10 (ICD-10) in women who gave birth 2007-8. The index group consisted of women 40 years of age or older (n = 8 203) were compared to a control group of women, younger than 40 years (n = 15 569) at childbirth.

Being born preterm or with low weight implies a risk of infertility and premature loss of ovarian function; a national register study.

Being born with non-optimal birth characteristics has several long-term consequences on health in general but also for the individual's reproductive pattern. In premature ovarian insufficiency (POI) the follicles are depleted or dysfunctional. This results in menopause before the age of 40, and for most of the affected women, it causes infertility.

Efficacy and safety of controlled ovarian stimulation using GnRH antagonist protocols for emergency fertility preservation in young women with breast cancer-a prospective nationwide Swedish multicenter study.

Study Question: How efficacious and safe are the current approaches to controlled ovarian stimulation (COS) aimed at fertility preservation (FP) in women with breast cancer (BC)?

Summary Answer: In women with BC undergoing COS aiming at egg/embryo cryopreservation, letrozole-based protocols and those randomly started were equally effective compared with conventional COS, and the overall survival was similar between the women that proceeded to FP and those who did not.

What Is Known Already: Cryopreservation of oocytes and embryos is an established method for FP in women with BC. Recent improvements to COS protocols include concomitant use of letrozole, random-cycle start day of stimulation and the use of GnRHa for the egg maturation trigger.

Human sperm displays rapid responses to diet.

The global rise in obesity and steady decline in sperm quality are two alarming trends that have emerged during recent decades. In parallel, evidence from model organisms shows that paternal diet can affect offspring metabolic health in a process involving sperm tRNA-derived small RNA (tsRNA). Here, we report that human sperm are acutely sensitive to nutrient flux, both in terms of sperm motility and changes in sperm tsRNA.

Low-molecular-weight-heparin increases Th1- and Th17-associated chemokine levels during pregnancy in women with unexplained recurrent pregnancy loss: a randomised controlled trial.

Low-molecular-weight heparin (LMWH) is widely used to treat recurrent pregnancy loss (RPL) because of its anti-coagulant effects. Although in vitro studies have suggested additional immunological effects, these are debated. We therefore investigated whether LMWH could modulate immune responses in vivo during pregnancy of women with unexplained RPL.

Diagnostics of DNA fragmentation in human spermatozoa: Are sperm chromatin structure analysis and sperm chromatin dispersion tests (SCD-HaloSpermG2 ) comparable?

Men affected with idiopathic infertility often display basic spermiogramme values similar to fertile individuals, questioning the diagnostic impact of the World Health Organization (WHO) thresholds used. This study explored sperm DNA fragmentation in single ejaculates from 14 fertile donors and 42 patients with idiopathic infertility providing semen for assisted reproductive techniques in a university fertility clinic. Each ejaculate was simultaneously studied for sperm DNA fragmentation by the flow cytometer-based sperm chromatin structure analysis (SCSA) and the new light-microscopy-based sperm chromatin dispersion assay (SCD-HaloSpermG2 ), before and after sperm selection for in vitro fertilisation with a colloid discontinuous gradient.

Evaluation of risk factors' importance on adverse pregnancy and neonatal outcomes in women aged 40 years or older.

Background: Women of advanced age (40 years or older) are generally, at risk for pregnancy and delivery related problems. In addition, there is limited knowledge on being of advanced age and having been given Assisted Reproductive Treatment (ART) and its association with negative obstetric outcomes. Therefore, data from the Swedish Medical Birth Register was used to investigate pregnancy and neonatal outcomes for women aged 40 or more who had given birth.

The prevalence of primary ovarian insufficiency in Sweden; a national register study.

Background: The current estimates of the prevalence of primary ovarian insufficiency (POI) are very variable, but are in most studies believed to be around 1%. It is also very likely tat the prevalence of POI differs between countries and over time. We therefore aimed to assess the prevalence of primary ovarian insufficiency in Sweden.

Reduced live-birth rates after IVF/ICSI in women with previous unilateral oophorectomy: results of a multicentre cohort study.

Study Question: Is there a reduced live-birth rate (LBR) after IVF/ICSI treatment in women with a previous unilateral oophorectomy (UO)?

Summary Answer: A significantly reduced LBR after IVF/ICSI was found in women with previous UO when compared with women with intact ovaries in this large multicentre cohort, both crudely and after adjustment for age, BMI, fertility centre and calendar period and regardless of whether the analysis was based on transfer of embryos in the fresh cycle only or on cumulative results including transfers using frozen-thawed embryos.

What Is Known Already: Similar pregnancy rates after IVF/ICSI have been previously reported in case-control studies and small cohort studies of women with previous UO versus women without ovarian surgery. In all previous studies multiple embryos were transferred.

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.

Men becoming fathers by intracytoplasmic sperm injection were more often born small for gestational age.

Being born with nonoptimal birth characteristics decreases the chance of becoming a father. Urogenital malformations as well as metabolic syndrome are more common in men born small for gestational age (SGA) and could be contributing factors to the reduced fertility rate seen in these men. It could imply that men becoming fathers by assisted reproductive technology (ART) more often are born with low birth weight (LBW), preterm, and/or SGA than men conceiving without treatment and also that men where intracytoplasmic sperm injection (ICSI) had to be performed more often are born with nonoptimal birth characteristics than men where conventional in vitro fertilization (IVF) successfully could be used.

Internet-delivered applied relaxation for vasomotor symptoms in postmenopausal women: lessons from a failed trial.

Internet-delivered therapies have a short history and promising results have been shown for several health problems, particularly for psychiatric conditions. This study was a first attempt to evaluate whether Internet-delivered applied relaxation for hot flushes in postmenopausal women may be useful. Due to a high drop-out rate the study was prematurely terminated after inclusion of approximately two thirds of calculated women.

Effects of applied relaxation on vasomotor symptoms in postmenopausal women: a randomized controlled trial.

Objective: This work aimed to study the efficacy of group therapy with applied relaxation on vasomotor symptoms and health-related quality of life in postmenopausal women.

Methods: In this open, randomized controlled trial, 60 healthy postmenopausal women with at least seven moderate to severe hot flashes per 24 hours were randomized to either group therapy with applied relaxation (n = 33) or untreated control group (n = 27) for 12 weeks. A follow-up visit was scheduled 3 months after the end of therapy or participation in the control group.

Effects of acupuncture, applied relaxation, estrogens and placebo on hot flushes in postmenopausal women: an analysis of two prospective, parallel, randomized studies.

Objective: To assess if transdermal or oral estrogens, acupuncture and applied relaxation decrease the number of menopausal hot flushes/24 h and improve climacteric symptoms, as assessed by the Kupperman index, more than transdermal placebo treatment.

Setting: An outpatient clinic at a Swedish university hospital.

Methods: A total of 102 postmenopausal women were recruited to two studies performed in parallel.

Psychological well-being improves in women with breast cancer after treatment with applied relaxation or electro-acupuncture for vasomotor symptom.

The aim of this study was to evaluate the effect of applied relaxation and electro-acupuncture (EA) on psychological well-being in breast cancer-treated women with vasomotor symptoms. Thirty-eight breast cancer-treated postmenopausal women with vasomotor symptoms were included in the study. They were randomized to either treatment with electro-acupuncture (EA) (n = 19, three of them with tamoxifen) or applied relaxation (AR) (n = 19, five of them with tamoxifen) over a 12-week study period with six months follow-up.

Vasomotor symptoms decrease in women with breast cancer randomized to treatment with applied relaxation or electro-acupuncture: a preliminary study.

Objective: To evaluate the effect of applied relaxation and electro-acupuncture on vasomotor symptoms in women treated for breast cancer.

Methods: Thirty-eight postmenopausal women with breast cancer and vasomotor symptoms were randomized to treatment with electro-acupuncture (n = 19) or applied relaxation (n = 19) during 12 weeks. The number of hot flushes was registered daily in a logbook before and during treatment and after 3 and 6 months of follow-up.

Applied relaxation and oral estradiol treatment of vasomotor symptoms in postmenopausal women.

Objective: The aim was to evaluate and compare the effects of applied relaxation and oral estradiol treatment on hot flushes, mood and psychological wellbeing in postmenopausal women.

Patients And Methods: In a prospective study, 30 postmenopausal women with vasomotor symptoms were randomized to applied relaxation or oral estradiol treatment during 12 weeks with 6 months follow-up. Number and severity of flushes were registered daily and Kupperman's Index and a general estimate of climacteric symptoms, Mood Scale and Symptom Check List were completed at baseline, 4, 8 and 12 weeks of treatment, and 3 and 6 months after therapy.
