Since the first description of successful human in vitro fertilization in 1978, researchers and clinicians have been striving to improve the efficacy and safety of the technique. Advances in technology and in our understanding of human reproduction have contributed to increased success rates and decreased rates of higher order multiple births. However, there is still room for improvement as 'unexplained infertility' still affects many couples, and the incidence of twin pregnancies remains…

Recent Advances in Assisted Reproductive Technology
TLDR
Current optimizations surrounding the delivery of in vitro fertilization including the utilization of minimal stimulation protocols and gonadotropin releasing hormone (GnRH) agonist cycle triggers are being increasingly utilized to maximize patient safety.
Psychological stress during in vitro fertilization and embryo transfer is influenced by the patients’ background and gender
TLDR
Findings will prove helpful in guiding psychological therapy and counseling for couples attempting to conceive by in vitro fertilization and fertility status also influenced anxiety levels.
Evolution of the egg: new findings and challenges.
TLDR
It is suggested that the rapid evolution of egg components and the mechanisms behind sperm-egg interactions are integrally connected, and delve in depth into each component of the egg's extracellular matrices.

Predictive factors for embryo implantation potential.
Birth of a healthy infant after preimplantation confirmation of euploidy by comparative genomic hybridization.
TLDR
This report on the case of a 38-year-old woman with a long history of infertility describes the use of comparative genomic hybridization to determine that all the chromosomes of a single embryo were free of aneuploidy, resulting in the birth of a healthy infant.
In vitro oocyte maturation for the treatment of infertility associated with polycystic ovarian syndrome: the French experience.
TLDR
The results show that IVM may be offered as an alternative to conventional IVF and to ovarian drilling in women with PCOS and the role of IVM in the therapeutic armamentarium for this condition should be further clarified.
Oocyte Maturation in Assisted Reproductive Techniques
TLDR
The techniques used for the IVM of oocytes and the role of hormones and growth factors in IVM and subsequent fertilization and early embryonic development are presented.
The in vitro growth and maturation of follicles.
TLDR
In large animals and humans, the complete in vitro growth and maturation of oocytes is only likely to be achieved following the development of a multistage strategy that closely mimics the ovary in vivo, and this approach will be initiated in situ by the culture of ovarian cortex.
Large offspring syndrome in cattle and sheep.
TLDR
Four different situations have been identified that result in the large offspring syndrome: in vitro embryo culture, asynchronous embryo transfer into an advanced uterine environment, nuclear transfer and maternal exposure to excessively high urea diets.
In-vitro maturation of human oocytes from regularly menstruating women may be successful without follicle stimulating hormone priming.
TLDR
FSH priming did not increase the number of oocytes obtained per aspiration and did not improve on maturation to metaphase II, cleavage rate or embryo development, but the implantation potential of IVM embryos may be improved by maturation for 36 h compared to 48 h.
