First 15 Years of Assisted Reproductive Technology Using Washed Sperm in HIV-Positive Individuals Under Antiretroviral Therapy: Sweden's Nationwide Outcomes.

Antiretroviral therapy has made HIV a chronic infectious disease. In Sweden, assisted reproductive technologies using sperm washing were implemented in 2004 for treatment of all HIV-positive males in serodiscordant couples at Karolinska Hospital in Stockholm. This study aimed to assess efficacy and safety of this approach and to investigate the effect of antiretroviral regimens on sperm quality of men treated for HIV.

Ambient black carbon particles in human ovarian tissue and follicular fluid.

Evidence indicates a link between exposure to ambient air pollution and decreased female fertility. The ability of air pollution particles to reach human ovarian tissue and follicles containing the oocytes in various maturation stages has not been studied before. Particulate translocation might be an essential step in explaining reproductive toxicity and assessing associated risks.

Setting: Twenty gynecology clinics in the Russian Federation.

DNA methylation differences at birth after conception through ART.

Study Question: Is there a relation between ART and DNA methylation (DNAm) patterns in cord blood, including any differences between IVF and ICSI?

Summary Answer: DNAm at 19 CpGs was associated with conception via ART, with no difference found between IVF and ICSI.

What Is Known Already: Prior studies on either IVF or ICSI show conflicting outcomes, as both widespread effects on DNAm and highly localized associations have been reported. No study on both IVF and ICSI and genome-wide neonatal DNAm has been performed.

Dydrogesterone as an oral alternative to vaginal progesterone for IVF luteal phase support: A systematic review and individual participant data meta-analysis.

The aim of this systematic review and meta-analysis was to conduct a comprehensive assessment of the evidence on the efficacy and safety of oral dydrogesterone versus micronized vaginal progesterone (MVP) for luteal phase support. Embase and MEDLINE were searched for studies that evaluated the effect of luteal phase support with daily administration of oral dydrogesterone (20 to 40 mg) versus MVP capsules (600 to 800 mg) or gel (90 mg) on pregnancy or live birth rates in women undergoing fresh-cycle IVF (protocol registered at PROSPERO [CRD42018105949]). Individual participant data (IPD) were extracted for the primary analysis where available and aggregate data were extracted for the secondary analysis.

Attitudes and experiences of health care professionals when caring for transgender men undergoing fertility preservation by egg freezing: a qualitative study.

Background: As gender-affirming treatment may have a negative impact on fertility, reproductive health counseling to patients seeking medical or surgical gender-affirming treatment should be provided, including the option to undergo fertility preservation (FP). Experiences of transgender men undergoing FP treatments aimed at oocyte freezing have reported a negative impact of the treatments on gender dysphoria. No previous studies have investigated the experiences of health care professionals' (HCP) when caring for transgender men undergoing such treatments.

Human induced pluripotent stem cells from two azoospermic patients with Klinefelter syndrome show similar X chromosome inactivation behavior to female pluripotent stem cells.

Study Question: Does the X chromosome inactivation (XCI) of Klinefelter syndrome (KS)-derived human induced pluripotent stem cells (hiPSCs) correspond to female human pluripotent stem cells (hPSCs) and reflect the KS genotype?

Summary Answer: Our results demonstrate for the first time that KS-derived hiPSCs show similar XCI behavior to female hPSCs in culture and show biological relevance to KS genotype-related clinical features.

What Is Known Already: So far, assessment of XCI of KS-derived hiPSCs was based on H3K27me3 staining and X-inactive specific transcript gene expression disregarding the at least three XCI states (XaXi with XIST coating, XaXi lacking XIST coating, and XaXe (partially eroded XCI)) that female hPSCs display in culture.

Study Design, Size, Duration: The study used hiPSC lines generated from two azoospermic patients with KS and included two healthy male (HM) and one healthy female donor.

The Uppsala-Stockholm Assisted Reproductive Techniques (UppStART) study.

Purpose: The Uppsala-Stockholm Assisted Reproductive Techniques (UppStART) study is a prospectively recruited sample of couples undergoing assisted reproduction in Stockholm and Uppsala county in Sweden. The study was initiated to (1) investigate possible changes in the epigenetic profile of infants inferred through the ART procedures and their consequence and (2) to assess the impact of lifestyle and health exposures on treatment outcome.

Participants: Recruitment took place between September 2011 and December 2013, and in vitro fertilisation (IVF) cycles initiated and pregnancies conceived during this time were followed until December 2014.

A Phase III randomized controlled trial of oral dydrogesterone versus intravaginal progesterone gel for luteal phase support in fertilization (Lotus II): results from the Chinese mainland subpopulation.

Lotus II, a randomized, open-label, multicenter, international study compared the efficacy and safety of oral dydrogesterone versus micronized vaginal progesterone (MVP) gel for luteal support in IVF. A prespecified subgroup analysis was performed on 239 Chinese mainland subjects from the overall study population ( = 1034), who were randomized to oral dydrogesterone 30 mg or 8% MVP gel 90 mg daily from the day of oocyte retrieval until 12 weeks of gestation. The aim was to demonstrate non-inferiority of oral dydrogesterone to MVP gel, assessed by the presence of a fetal heartbeat at 12 weeks of gestation.

Endometriosis and cumulative live birth rate after fresh and frozen IVF cycles with single embryo transfer in young women: no impact beyond reduced ovarian sensitivity-a case control study.

Purpose: To investigate the impact of symptomatic and surgically confirmed endometriosis on ovarian sensitivity index (OSI) and cumulative live-birth rates (LBR) using predominantly single embryo transfer (SET).

Methods: Cross-sectional case-control study in a University-based ART program. Women with symptomatic and surgically confirmed endometriosis (N = 172), who underwent IVF/ICSI at Karolinska University Hospital were compared to controls without clinically suspected endometriosis (N = 2585).

Increased incidence of obstetric and perinatal complications in pregnancies achieved using donor oocytes and single embryo transfer in young and healthy women. A prospective hospital-based matched cohort study.

In this single-center matched-cohort study, women who underwent IVF/ICSI with donor oocytes between 2007 and 2014 (n = 259) were compared to women undergoing autologous cycles during the same time period (n = 515). The matching (1:2) took into consideration the women's age, type of treatment (IVF/ICSI), and year of embryo transfer. All women were healthy and below 40 years of age at the time of IVF/ICSI, and the treatments were performed using a strict policy of single embryo transfer.

A prospective investigation of perceived stress, infertility-related stress, and cortisol levels in women undergoing in vitro fertilization: influence on embryo quality and clinical pregnancy rate.

Introduction: Women undergoing fertility treatment experience high levels of stress. However, it remains uncertain if and how stress influences in vitro fertilization (IVF) cycle outcome. This study aimed to investigate whether self-reported perceived and infertility-related stress and cortisol levels were associated with IVF cycle outcomes.

Does ovarian stimulation regimen affect IVF outcome? a two-centre, real-world retrospective study using predominantly cleavage-stage, single embryo transfer.

In this study, ovarian stimulation using highly purified human menopausal gonadotrophin (HP-HMG) and recombinant FSH (rFSH) for IVF were compared in two large assisted reproduction technique centres in Sweden. A total of 5902 women underwent 9631 oocyte retrievals leading to 8818 embryo transfers (7720 on day 2): single embryo transfers (74.2%); birth rate per embryo transfer (27.

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.

Weekend-free scheduled IVF/ICSI procedures and single embryo transfer do not reduce live-birth rates in a general infertile population.

Introduction: Scheduling of ovum pickup only on weekdays may result in cases of apparently suboptimal timing for human chorionic gonadotropin and ovum pickup. This study aimed to assess whether live-birth rates were reduced in women with a potentially suboptimal day for human chorionic gonadotropin and ovum pickup to avoid weekend work, according to ultrasonographic data on the day of human chorionic gonadotropin planning.

Material And Methods: An evaluation of the optimal human chorionic gonadotropin priming date was performed in treatment protocols of 1000 consecutive patients undergoing their first in vitro fertilization/intracytoplasmatic sperm injection with single-embryo transfer.

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.

One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation.

Objective: To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child.

Design: Part of an observational study.

Setting: University teaching hospital.

Postoperative AMH reduction is not associated with reduced fecundity two years following ovarian cyst surgery.

In a prospective study, we investigated the impact of anti-Müllerian hormone (AMH) changes following ovarian cyst surgery on the probability to achieve pregnancy and live birth. Women of reproductive age (n = 60) were included before surgery for benign ovarian cysts. Serum AMH concentrations were determined pre- and postoperative at 6 and 24 months.

Mycoplasma genitalium serum antibodies in infertile couples and fertile women.

Objectives: The association between Mycoplasma genitalium (M. genitalium) serum antibodies and infertility in women and men, as well as infertility subtypes, was investigated.

Methods: Stored serum was obtained from two patient cohorts: infertile couples (239 women and 243 men) attending a gynaecological outpatient clinic between October 1997 and February 2001 and 244 age-matched spontaneously pregnant women.

Full-term newborn after repeated ovarian tissue transplants in a patient treated for Ewing sarcoma by sterilizing pelvic irradiation and chemotherapy.

We report the first successful transplantation of cryopreserved ovarian cortical tissue into heavily irradiated tissues in a patient who had received sterilizing pelvic radiotherapy (54 Gy) and 40 weeks of intensive high-dose chemotherapy for the treatment of Ewing's sarcoma 14 years earlier. Repeated transplantation procedures were required to obtain fully functional follicular development. Enlargement of the transplants over time and increase of the size of the uterus were demonstrated on sequential ultrasonographic examinations.

Quality management systems for your in vitro fertilization clinic's laboratory: Why bother?

Several countries have in recent years introduced prescribed requirements for treatment and monitoring of outcomes, as well as a licensing or accreditation requirement for in vitro fertilization (IVF) clinics and their laboratories. It is commonplace for Assisted Reproductive Technology (ART) laboratories to be required to have a quality control system. However, more effective Total Quality Management systems are now being implemented by an increasing number of ART clinics.
