There are considerable knowledge gaps among Australians of reproductive age about the impact on fertility of age, weight, smoking, and timing of sex.
Effective anatomical and functional status of the lower uterine segment at term Estimating the risk of uterine dehiscence by ultrasound
Sonographic lower uterine segment evaluation may be a good noninvasive, repeatable, safe technique for defining profile risk of uterine dehiscence or worse in women with previous cesarean section, especially more than 18 months later.
The level of plasma soluble E-cadherin was elevated in patients with pelvic inflammatory disease as compared with that in normal controls and in the same patients after they received treatment.
In a primary ovarian insufficiency group, we identified one mutation and a frequent variant of the NR5A1/SF-1 gene. This work confirms the important role of steroidogenic factor 1 in ovarian function.
Pretreatment antimullerian hormone levels determine rate of posttherapy ovarian reserve recovery Acute changes in ovarian reserve during and after chemotherapy
Young women undergoing chemotherapy experience acute changes in ovarian reserve that recover in the months after therapy is completed. The rate of recovery of AMH is impacted by pretreatment levels.
We report the first-year results of the longest-lived human uterus allograft.
In cryopreserved semen from men with newly diagnosed cancer, all specimens show severe decline in postthaw total motile sperm count, with most severe reductions in the myeloid leukemia group.
Effects of pregnancy planning fertility and Assisted Reproductive Treatment on child behavioral problems at 5 and 7 years Evidence from the Millennium Cohort Study
Children conceived by ART had higher mean total difficulties scores than planned, naturally conceived children, yet scores mostly remained within the “normal” range, and there was no significant increase in clinically relevant behavioral problems.
Implications of Assisted Reproductive Technologies on Term Singleton Birth weight An Analysis of 25777 Children in the National Assisted Reproduction Registry of Japan
An analysis of 25,777 singleton full-term births after assisted reproduction showed that extended embryo culturing and frozen-thawed embryo transfer increased birth weight and that ovarian stimulation is a risk factor for low birth weight in fresh embryo transfer cycles.
Cell derived microparticles and vascular pregnancy complications A systematic and comprehensive review
Pregnancy showed a cMP increase. Differences in numbering and types of cMP in normal pregnancy, RM and PE have been demonstrated. Endothelial-derived cMP are increased in patients with antiphospholipid antibodies.
This study highlights the risk involving various genotypes and alleles of the interleukin (IL) 4 (C590T), IL-6 (G174C), IL-10 (1082A/G and 819C/T), and interferon-g (+874 A/T) polymorphism with recurrent miscarriage.
Changes of human decidual natural killer cells cocultured with YFP Toxoplasma gondii Implications for abnormal pregnancy
Human decidual natural killer (dNK) cells were cocultured with Toxoplasma gondii in vitro. Changes in dNK cell activities likely contribute to abnormal pregnancy outcomes due to infection with T. gondii.
Corifollitropin alpha followed by rFSH in a GnRH antagonist protocol for poor ovarian responder patients An observational pilot study
Although pregnancy rates in “Bologna-criteria poor ovarian responders” treated with corifollitropin alpha in a GnRH antagonist protocol are low, this should be interpreted with caution given the very poor prognosis of this population.
Use of MI oocytes matured in vitro during routine ICSI is associated with multinucleation, poorer embryo quality, and lower clinical pregnancy and implantation rates.
Morphologic abnormalities in 2 year old children born after in vitro fertilization intracytoplasmic sperm injection with preimplantation genetic screening Follow up of a randomized controlled…
In this follow-up study of a randomized controlled trial on preimplantation genetic screening (PGS), the percentage of 2-year-old children with one or more major abnormality in the group born after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) with PGS did not exceed the percentage in those born after IVF/ICSI without PGS.
We developed a microfluidic device that can reduce the treatment time of intracytoplasmic sperm injection and compared the treatment time for porcine sperm injection using the method employing this device and the conventional microdroplet method.
The cumulative probability of liveborn multiples after in vitro fertilization A cohort study of more than 10000 women
Multiple-gestation pregnancies are the most significant morbidity after IVF, yet national data reports outcomes as per cycle pregnancy rates. This study provides estimates of the cumulative incidence of liveborn multiples and reports a low cumulative incidence of liveborn multiples, especially triplets.
A matched cohort comparison of single embryo transfers in fresh and frozen thawed embryo transfer cycles
Impaired endometrial receptivity following ovarian stimulation appears to be primarily through embryo-endometrium asynchrony.
Diagnosis and Treatment of Diminished Ovarian Reserve in assisted reproductive technology Cycles of Women Up to Age 40 Years The Role of Insurance Mandates
DOR (up to age 40) is more prevalent in ART cycles performed in states lacking mandated ART coverage than in states with coverage. Mandates may impact outcomes in DOR cycles.

This retrospective study analyzed the risk factors for development of significant liver dysfunction in pregnancy and it’s specific etiologies. Assisted reproduction was significantly associated with liver test abnormalities.
Overweight men with nonobstructive azoospermia have worse pregnancy outcomes after microdissection testicular sperm extraction
Overweight men have lower clinical pregnancy rate after microdissection testicular sperm extraction and intracytoplasmic sperm injection compared with men with normal weight. Men with body mass index >43 kg/m2 did not contribute to any pregnancies despite successful sperm retrieval.
Clinical value of sperm DNA damage should be assessed in motile sperm fraction rather than whole ejaculated sperm
DNA damage results of ejaculated sperm do not accurately reflect DNA status of motile sperm, so sperm DNA damage should be assessed in motile sperm fraction rather than whole ejaculated sperm.
The impact of surgical sperm retrieval on the in vitro fertilization outcomes of infertile patients with a temporary ejaculation failure on their oocyte retrieval day
For patients with temporary ejaculation failure, surgical sperm retrieval compromised the outcomes of fresh embryo transfers, whereas it did not affect the outcomes of thawed embryo transfers.
