An increase in imprinting disorders in children conceived though assisted reproductive technologies (ARTs) has been the subject of several reports. The transmission of imprinting errors from the sperm of infertile fathers is believed to be a possible reason for the increased occurrence of these disorders. However, whether the imprinting alterations in sperm affect ART outcomes and the imprinting of offspring is unclear. In the current study, we analyzed the methylation of H19, SNRPN and KCNQ1OT1 by pyrosequencing sperm samples from 97 infertile patients and 31 proven fertile males as well as cord blood samples from 13 infantswho were conceived by infertile parents through intracytoplasmic sperm injection (ICSI) and 30 healthy newborns who were conceived naturally...

OBJECTIVES: The objectives of this study were to assess (1) the expected cost of a live birth (LB) after in vitro fertilization with two different gonadotropin treatments [high purified human menopausal gonadotropin (HP-hMG) and recombinant follicle-stimulating hormone (rFSH)] as the single cost variable, and (2) the cost effectiveness of HP-hMG relative to rFSH in the context of the routine practice of assisted reproductive technology (ART) in France. METHODS: A Markov model was developed to simulate the therapeutic management, the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) courses, and the effects of complications in hypothetical cohorts of 30,000 patients undergoing IVF/ICSI with fresh embryo transfer (up to four attempts) using data from the MERIT and MEGASET clinical trials or from French routine ART practice...

The selection of sperm cells possessing normal morphology and motility is crucial for many assisted reproductive technologies (ART), especially for intracytoplasmic sperm injection (ICSI), as sperm quality directly affects the probability of inducing healthy pregnancy. We present a novel platform for real-time quantitative analysis and selection of individual sperm cells without staining. Towards this end, we developed an integrated approach, combining interferometric phase microscopy (IPM), for stain-free sperm imaging and real-time automatic analysis based on the sperm cell 3D morphology and contents, with a disposable microfluidic device, for sperm selection and enrichment...

Clinical varicoceles have been associated with impaired semen parameters and male-factor infertility. Varicocele repair can improve live birth rates for men with clinical varicocele. Varicocelectomy is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). Here we review the literature examining varicocelectomy before ART to evaluate whether improved pregnancy outcomes are realized. Although insufficient evidence exists to determine if correcting a varicocele improves IUI outcomes, a clinical benefit is observed when correcting a clinical varicocele in oligospermic and nonobstructed azoospermic men before IVF/ICSI...

Assisted reproductive technology (ART) is used primarily for infertility treatments to achieve pregnancy and involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation. Moreover, preimplantation genetic diagnosis (PGD) of ART is used in couples for genetic reasons. In ART treatments, gametes and zygotes are exposed to a series of non-physiological processes and culture media. Although the majority of children born with this treatment are healthy, some concerns remain regarding the safety of this technology...
