Artificial oocyte activation with calcium ionophore does not cause a widespread increase in chromosome segregation errors in the second meiotic division of the oocyte
Artificial oocyte activation with calcium ionophore does not cause a widespread increase in chromosome segregation errors in the second meiotic division. However, we recommend that it is applied selectively to patients with specific indications.

The assisted oocyte activation protocol with the use of ionomycin is more efficient than the use of A23187 in both mouse and human oocytes.
The authors identify PCOS as an independent risk factor for the development of specific pregnancy complications in singleton pregnancies after IVF with or without intracytoplasmic sperm injection.
Cross border reproductive care in North America: a pilot study testing a prospective data collection program for IVF clinics in Canada and the United States
Nonidentifying summary data on cross-border reproductive care were considered important by responding Canadian Fertility and Andrology Society and Society for Assisted Reproductive Technology members. However, only one center from these societies was willing to collect and submit data.
Treatment of infertility does not increase the risk of ovarian cancer among women with a BRCA1 or BRCA2 mutation
These findings suggest that treatment for infertility does not significantly increase the risk of ovarian cancer among women with a BRCA mutation.
The PROMISe trial: a pilot randomized placebo controlled trial of magnetic resonance guided focused ultrasound for uterine fibroids
A placebo effect may explain some of the improvement in fibroid symptoms after magnetic resonance-guided focused ultrasound among women with uterine fibroids.
Cancer survivors commonly experience amenorrhea, especially those who receive chemotherapy, are nulligravida, or are older at diagnosis. Most women resume menses within 2 years of diagnosis or not at all.
A discussion of how oocyte vitrification is clinically efficient for elective fertility preservation in the largest series reported to date and how the demand for this option is increasing.
Ethnicity or environment? Effects of migration on ovarian reserve among Bangladeshi women in the United Kingdom
Differences in ovarian reserve between age-matched Bangladeshis who moved to London as children or adults highlight the influence of developmental environments rather than ethnicity on the tempo of reproductive aging.
Norethindrone acetate or dienogest for the treatment of symptomatic endometriosis: a before and after study
Systematic change from norethindrone acetate to dienogest as first-choice progestin for endometriosis was associated with enhanced drug tolerability and similar improvement in pain relief, quality of life, and patient satisfaction.
Monochorionic diamniotic in vitro fertilization twins have a decreased incidence of twin to twin transfusion syndrome
The incidence of twin-to-twin transfusion syndrome is lower in in vitro fertilization versus spontaneously conceived monochorionic diamniotic twin pregnancies.
The magnitudes of risk for early pregnancy loss after in vitro fertilization for all infertility diagnoses were small. The risks were similar when transferring similar quality embryos in fresh or frozen cycles.
Urinary paraben concentrations and in vitro fertilization outcomes among women from a fertility clinic
Among a prospective cohort of women undergoing in vitro fertilization treatments at an academic fertility center, urinary methylparaben, propylparaben, and butylparaben concentrations were not associated with clinical in vitro fertilization outcomes.
Blastocyst development in single medium with or without renewal on day 3: a prospective cohort study on sibling donor oocytes in a time lapse incubator
Under a carefully controlled environment, human embryos can be cultured in a single medium up to the blastocyst stage with no need to renew the medium on day 3.
We discuss the different policies of centers regarding obesity and access to assisted reproductive technology.
Does the addition of growth hormone to the in vitro fertilization intracytoplasmic sperm injection antagonist protocol improve outcomes in poor responders? A randomized controlled trial
The addition of growth hormone to the antagonist protocol in poor-responder women undergoing in vitro fertilization/intracytoplasmic sperm injection cycles resulted in better cycle outcomes but did not significantly affect pregnancy rates.
Impact of pituitary suppression on antral follicle count and oocyte recovery after ovarian stimulation
We discuss how short-term pituitary suppression decreases antral follicle count.
Patients facing difficult decisions regarding disposition of their surplus embryos require further information about their options after treatment to make timely, comfortable, and informed choices.
Preimplantation genetic testing: polar bodies blastomeres trophectoderm cells or blastocoelic fluid?
The chromosome condition of DNA retrieved by blastocentesis was highly concordant with that found in trophectoderm cells, polar bodies, and blastomeres. Segmental abnormalities could also be detected in blastocoelic fluids.
Noninvasive assessment of polar bodies angle proves to be a practical tool for the selection of viable embryos and should be considered for inclusion in embryo selection parameters.
Pregnancy outcomes decline with increasing body mass index: analysis of 239127 fresh autologous in vitro fertilization cycles from the 2008-2010 Society for Assisted Reproductive Technology registry
Success rates in fresh autologous IVF cycles, including those done for specifically polycystic ovary syndrome or male-factor infertility, are highest in those with low and normal body mass indexes.
Time lapse deselection model for human day 3 in vitro fertilization embryos: the combination of qualitative and quantitative measures of embryo growth
This study presents a deselection model for human in vitro fertilization embryos independent of the insemination method, the qualitative component being more accurate when coupled with a quantitative component.
Effectiveness of semen washing to prevent human immunodeficiency virus (HIV) transmission and assist pregnancy in HIV discordant couples: a systematic review and meta analysis
Semen washing appears to be effective and safe, significantly reducing the risk of human immunodeficiency virus (HIV) transmission in HIV-discordant couples attempting to become pregnant by means of assisted reproduction.
Sperm DNA fragmentation and mitochondrial membrane potential combined are better for predicting natural conception than standard sperm parameters
Sperm DNA fragmentation and mitochondrial membrane potential combined are superior to standard sperm parameters in predicting natural conception.
Increased risk of incident chronic medical conditions in infertile men: analysis of United States claims data
Men diagnosed with male factor infertility had a significantly higher risk of adverse health outcomes in the years after an infertility evaluation.

Angiotensin II type 2 receptor is present in human spermatozoa and is associated with basic sperm parameters, especially motility.
We have come a long way in achieving, and preventing, pregnancy since 1966.

Effects of in vitro fertilization and maternal characteristics on perinatal outcomes: a population based study using siblings
Maternal characteristics of subfertile women are associated with a lower birthweight; in vitro fertilization treatment in itself does not additionally contribute to a lower birthweight in the offspring.
I have to say, I truly love the specialty we are fortunate enough to practice. What other area of medicine involves the laboratory and clinic so intimately intertwined, changes so rapidly, and can bring so much joy to patients? But how are we getting there? What has the trajectory of our field been? And what role do we, as clinicians, have to play in determining outcome?
