The freeze-all strategy has emerged as an alternative to fresh embryo transfer (ET) during in vitro fertilization (IVF) cycles. Although fresh ET is the norm during assisted reproductive therapies (ART), there are many concerns about the possible adverse effects of controlled ovarian stimulation (COS) over the endometrium. The supra-physiologic hormonal levels that occur during a conventional COS are associated with modifications in the peri-implantation endometrium, which may be related to a decrease in pregnancy rates and poorer obstetric and perinatal outcomes when comparing fresh to frozen-thawed embryo transfers...

Ashley M Eskew, Kenan R Omurtag
Ovarian hyperstimulation syndrome (OHSS) is one of the most frequent, serious and potentially lethal iatrogenic complications of controlled ovarian stimulation. Despite extensive research, the exact pathogenesis of this syndrome remains less clear, but there appears to be a relationship of increased vascular permeability mediated by HCG and other downstream mediators. Adequate experience with ovulation induction therapy and identifying patients with known risk factors are essential in preventing OHSS. As this is a completely iatrogenic disease numerous strategies have been investigated to help decrease the risk of OHSS and their effects on pregnancy and live birth rate...

The standard FSH treatment is based on a 3 months period, after which both quantitative/qualitative improvement of sperm parameters and increased pregnancy rate were reported. In this prospective clinical trial, for the first time, we studied (i) Sperm hyaluronic acid binding capacity after highly purified FSH (hpFSH) treatment; (ii) the effect after short-term and standard treatment on this functional parameter. As secondary objective, we analyzed three SNPs on FSHβ and FSHR genes to define their potential predictive value for responsiveness...

Progesterone is a steroid hormone of essential role in reproduction. In early pregnancy, it is responsible for preparation of endometrium for implantation process and maintenance of gestational sac in uterus, also by modulation of maternal immune system. Even though, several indices has been proposed as markers of endogenous progesterone synthesis (progesterone or luteinizing hormone measurements, endometrial biopsy), none has been proved to be reliable in detecting luteal phase defect. Currently, several pharmaceutical formulations are available, but in clinical setting the non-oral formulations seems to be effective in therapy...

Valentina Grisendi, Antonio La Marca
INTRODUCTION: In assisted reproduction technologies (ART) the controlled ovarian stimulation (COS) therapy is the starting point from which a good oocytes retrieval depends. Treatment individualization is based on ovarian response prediction, which largely depends on a woman's ovarian reserve. AMH and AFC are considered the most accurate and reliable markers of ovarian reserve. EVIDENCE ACQUISITION: A literature search was carried out for studies that addressed the ability of AMH and AFC to predict poor and/or excessive ovarian response in IVF cycles...

With the rapid development of assisted reproductive technology, various reproductive disorders have been effectively addressed. Acupuncture-like therapies, including electroacupuncture (EA) and transcutaneous electrical acupoint stimulation (TEAS), become more popular world-wide. Increasing evidence has demonstrated that EA and TEAS are effective in treating gynecological disorders, especially infertility. This present paper describes how to select acupoints for the treatment of infertility from the view of theories of traditional Chinese medicine and how to determine critical parameters of electric pulses of EA/TEAS based on results from animal and clinical studies...

Reshef Tal, David B Seifer
Ovarian reserve is a complex clinical phenomenon that is influenced by age, genetics and environmental variables. Although it is challenging to predict the rate of an individual's ovarian reserve decline, clinicians are often asked for advice about fertility potential and/or recommendations regarding the pursuit of fertility treatment options. The purpose of this review is to summarize the state-of-the-art of ovarian reserve testing (ORT), providing a guide for the Ob/Gyn generalist and reproductive endocrinologist...

Sperm DNA fragmentation (SDF) has been generally acknowledged as a valuable tool for male fertility evaluation. While its detrimental implications on sperm function were extensively investigated, little is known about the actual indications for performing SDF analysis. This review delivers practice based recommendations on commonly encountered scenarios in the clinic. An illustrative description of the different SDF measurement techniques is presented. SDF testing is recommended in patients with clinical varicocele and borderline to normal semen parameters as it can better select varicocelectomy candidates...
