Mariano Mascarenhas, Adam H Balen
This review attempts to summarize the known literature on high responders to ovarian stimulation during assisted reproductive techniques (ART). Response to gonadotrophins is subject to significant interindividual and intercycle variation, thus carrying a risk of high response or poor response to ovarian stimulation regimens. The main risk for high responders is the development of ovarian hyperstimulation syndrome (OHSS) which is associated with significant morbidity. Hence, the definition of high responders in the literature has primarily focussed on risk factors for OHSS...

BACKGROUND AND OBJECTIVES: The emerging association of assisted reproductive techniques (ART) with imprinting disorders represents a major issue in the scientific debate on infertility treatment and human procreation. We studied the prevalence of Beckwith-Wiedemann syndrome (BWS) in children conceived through ART to define the specific associated relative risk. METHODS: Patients with BWS born in Piemonte, Italy, were identified and matched with the general demographic data and corresponding regional ART registry...

Recent studies have evaluated the use of magnetic-activated cell sorting (MACS) to reduce apoptotic spermatozoa and improve sperm quality. However, the efficiency of using MACS alone, before or after sperm processing by density gradient centrifugation (DGC) has not yet been established. The purpose of this study is to determine the optimal protocol of MACS in assisted reproduction techniques (ART). Thus, we compared sperm quality obtained by DGC alone (DGC), DGC followed by MACS (DGC-MACS), MACS followed by DGC (MACS-DGC), and MACS alone (MACS), and found that the combined methods (MACS-DGC and DGC-MACS) led to retrieval of less spermatozoa with fragmented DNA compared to the single protocols...

Pregnancy success results from the interaction of multiple factors, among them are folliculogenesis and early embryonic development. Failure during these different processes can lead to difficulties in conception. Alternatives to overcome these problems are based on assisted reproductive techniques. Extracellular vesicles are cell-secreted vesicles present in different body fluids and contain bioactive materials, such as messenger RNA, microRNAs (miRNAs), and proteins. Thus, our hypothesis is that extracellular vesicles from follicular fluid from 3-6 mm ovarian follicles can modulate bovine embryo development in vitro...

PROBLEM: The use of in vitro maturation (IVM) as an alternative approach to the conventional assisted reproductive technique in clinical practice is limited due to low fertilization rate. The expression of Toll-like receptors (TLRs) as members of an innate immune system in cumulus cells are thought to affect fertilization. This study was aimed to evaluate the effect of IVM on TLR4 gene expression and fertilization rate in oocytes derived from IVM in comparison with in vivo matured one...

Semen banking is often advised to male patients undergoing chemotherapy as the damage induced is profound and often irreversible. However, low success rates of assisted reproductive techniques (ART) using banked semen have led to the quest for alternative methods to treat chemotherapy-induced infertility. The present study therefore aimed to study the role of resveratrol against cisplatin induced testicular damage. Male albino mice were divided into five groups (n = 6 each), viz. normal control, resveratrol vehicle (4% ethanol), Cisplatin (7...

A strong correlation between blastocyst morphology and implantation has been shown by many studies. The consequences and effects of assisted reproductive techniques on children's short and long-term health have always been a source of discussion. The obstetric and perinatal outcome of singletons according to blastocyst morphology has rarely been evaluated. The aim of this observational study is to determine whether a relationship exists between blastocyst morphology and obstetric and perinatal outcomes. A total of 799 singleton clinical pregnancies were analysed after transfer of a single fresh blastocyst on day 5 between 2006 and 2013...

There is an increasing request by patients or their representatives not to have some data registered in their clinical history or if such data exists to be deleted. Without doubt, this is so because such clinical data is accessed by various professionals who in most cases are not directly involved in caring for such patients. On the other hand, such data is copied and iteratively and unnecessary reproduced in various discharge reports and others forms. The problem arises when such controversial data refer to particularly sensitive clinical aspects such as assisted reproduction techniques, which invades personal and family privacy...

Tunnel malposition is one of the most common technical reasons for anterior cruciate ligament reconstruction failure. Small changes in tunnel placement can result in significant differences in outcome. More anatomic placement of the tunnels can lead to greater knee stability and a more accurate reproduction of native knee kinematics. This Technical Note describes 2 tibial tunnel-independent methods to obtain anatomic femoral tunnel placement. The all-inside anteromedial portal technique requires only minimal surgical incisions but allows precise femoral tunnel placement...

PURPOSE OF REVIEW: Vitamin D deficiency has been associated with a wide range of human disease states and the global epidemic, particularly in reproductive aged women, has led to a focus on this complex hormones role in human reproduction. Indeed vitamin D receptors are found throughout the reproductive tract in the ovary, endometrium, and the placenta. It has roles both in calcium-dependent and independent pathways. However, agreement upon the most appropriate way to assess vitamin D status and ultimately its activity at various sites has proven challenging...

In the modern era of HIV care, a multitude of clinical needs have emerged; one such need is the growing sub-specialty of HIV and reproductive health. In 2007, a study surveying Canadian fertility clinics found limited access to fertility services for HIV-positive patients. Given the extensive efforts made to address this lack of services, a follow-up assessment was warranted. This study aimed to compare the access to Canadian fertility clinics and services for HIV-positive individuals and couples in 2014 and 2007...

One of the cryopreservation methods that best preserves sperm function is vitrification. However, comparative studies have not been performed to evaluate the effect of nonpermeable cryoprotectors on sperm function for prolonged periods of time post-devitrification. These times are necessary, especially in in vitro fertilisation and intrauterine insemination, for gamete interaction and then fertilisation to occur, while maintaining motility to arrive at the fertilisation site. In this study, sucrose (.25 m) and trehalose (...

Ovarian hyperstimulation syndrome (OHSS) is a potentially life‑threatening, iatrogenic complication that occurs during assisted reproduction. Polycystic ovarian syndrome (PCOS) significantly increases the risk of OHSS during controlled ovarian stimulation. Therefore, a more effective early prediction technique is required in PCOS patients. Quantitative proteomic analysis of serum proteins indicates the potential diagnostic value for disease. In the present study, the authors revealed the differentially expressed proteins in OHSS patients with PCOS as new diagnostic biomarkers...

There has been a dramatic rise in preterm births in developed countries owing to changes in clinical practices and greater use of assisted reproductive techniques. However, few studies have examined the growth and outcomes of preterm infants according to the type of feeding (with fortified breast milk or formula). The purpose of this study was to examine the effect of breast milk feedings and formula on the growth and short-term outcomes of preterm infants in Hong Kong. In a single-center retrospective cohort study, we included 642 preterm infants at gestational age <37 weeks with birth weights <2200 g...

Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter)...
