background: assisted reproductive technologies (art) are known as a treatment for infertility in which oocyte undergoes manipulation outside body. the aim of this study was to study the evaluation of birth defects in infants conceived through assisted reproductive technologies (art) and compare them with naturally-conceived infants. materials and methods: in this retrospective study, four hundr...

this is the first report implementing combined density gradient centrifugation/zeta (dgc/zeta) sperm selection procedure for a couple with eleven previous intra cytoplasmic sperm injection/ in vitro fertilization (icsi/ivf) failure cycles. semen analysis was carried out according to world health organization criteria. protamine deficiency, dna fragmentation and morphology were assessed by chrom...

background: monozygotic monochorionic triplet pregnancy with conjoined twins is a very rare condition and is associated with many complications. case: in this study, we describe a monochorionic–diamniotic triplet pregnancy after in vitro fertilization with an intracytoplasmic sperm injection. at a gestational age of 6 weeks and 4 days of pregnancy one gestational sac was observed, and at a gest...

In this paper, the development of a computer controlled piezo manipulation system for biomedical applications such as intra-cytoplasmic sperm injection (ICSI) is presented. The hardware setup and the control strategies will be described in full details to illustrate the advantages of this approach as compared to other manual-based injection methods.

evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear dna integrity of spermatozoa. it has been suggested that altered nuclear chromatin struc...
