Novel technologies for selecting the best sperm for in vitro fertilization and intracytoplasmic sperm injection

Monday, March 18, 2013
This review examines new techniques that are designed to prepare a clean “normal” sperm population or that assist in selecting an individual “normal” spermatozoon.

Intracytoplasmic sperm injection with microsurgically retrieved spermatozoa in azoospermic men infected with human immunodeficiency virus 1 or hepatitis C virus The EP43 AZONECO ANRS study

Friday, March 1, 2013
Density gradient and washing can remove HCV RNA or HIV RNA from microsurgical epididymal sperm aspiration or testicular sperm extraction samples obtained from HCV- or HIV-infected azoospermic men before ICSI.

Are imprinting disorders more prevalent after human in vitro fertilization or intracytoplasmic sperm injection

Friday, March 1, 2013
There is solid evidence that Beckwith-Wiedemann syndrome is significantly positively associated with IVF or ICSI. There is no proof for a causal relationship between imprinted diseases and ART.

The value of chromosomal analysis in oligozoospermic men

Thursday, November 29, 2012
We found that in oligozoospermic male intracytoplasmic sperm injection candidates, the abnormal karyotype rate was <2%. The small risk of conceiving a child with unbalanced structural chromosomal abnormalities may not justify karyotyping these men.

Intracytoplasmic sperm injection ICSI for non male factor infertility A committee opinion

Thursday, November 29, 2012
This committee opinion assesses the literature, where available, to identify situations where intracytoplasmic sperm injection may be indicated in the absence of an identified male factor.

Obstetric and Perinatal outcomes in singleton pregnancies resulting from the transfer of frozen thawed versus fresh embryos generated through in-vitro fertilization treatment A systematic review and meta-analysis

Tuesday, June 12, 2012
Pregnancies arising from the transfer of frozen thawed IVF embryos have better obstetric and perinatal outcomes based on the observational data.

Frozen-thawed spermatozoa from oligozoospermic ejaculates are susceptible to in situ DNA fragmentation in PVP-based sperm immobilization medium

Friday, June 8, 2012
Polyvinylpyrrolidone-based medium can induce sperm DNA fragmentation during intracytoplasmic sperm injection, and frozen-thawed sperm from oligozoospermic ejaculates are more susceptible to in situ DNA fragmentation.

Integration of immunodeficiency virus in oocytes via intracytoplasmic injection: possible but extremely unlikely

Thursday, June 7, 2012
Human oocytes can be infected with HIV via ICSI when high amounts of virus are injected, but the chances that an infection will occur in a clinical setting are less than 0.00002%.

Defects in imprinting and genome-wide DNA methylation are not common in the in vitro fertilization population

Friday, June 1, 2012
The examination of 66 in vitro fertilization–conceived children and 69 control children revealed no imprinting abnormalities at H19, KCNQ1OT1, SNRPN, or IGF2. Satellite 2 methylation was normal, and no global changes in methylation were detected.

Intracytoplasmic sperm injection in partial globozoospermia

Thursday, May 31, 2012
Intracytoplasmic sperm injection is the most effective and safe treatment in case of partial globozoospermia, although spontaneous pregnancies do occur in this population.

Birth defects in children conceived by in vitro fertilization and intracytoplasmic sperm injection: a meta-analysis

Wednesday, May 30, 2012
Children conceived by IVF and/or ICSI are at significantly increased risk for birth defects, and there is no risk difference between IVF children and ICSI children.

Developmental potential of embryos from intracytoplasmic sperm injection cycles containing fragmented oocytes

Friday, May 25, 2012
Fragmented oocytes occur rarely in intracytoplasmic sperm injection cycles, but their presence is associated with reduced developmental potential of sibling oocytes and lower implantation and pregnancy rates.

Development and current applications of assisted fertilization

Thursday, May 24, 2012
We describe the early steps that brought forth the development of intracytoplasmic sperm injection and its role in assisted reproduction techniques.

Contemporary aspects of male gamete (dys)function: aiming towards optimizing the treatment of fertilization disorders

Thursday, May 24, 2012
We describe the early steps that brought about the establishment of assisted fertilization techniques culminating in intracytoplasmic sperm injection (ICSI) along with presentations of current diagnostic screening methods for spermatozoal (dys)function.

Outcomes of singleton births after blastocyst versus nonblastocyst transfer in assisted reproductive technology

Wednesday, May 23, 2012
Retrospective cohort analysis of 4,202 births resulting from blastocyst versus nonblastocyst transfer demonstrated no significant difference in maternal and perinatal outcomes, although blastocyst transfer may increase preeclampsia and placenta previa.

Effect of oocyte quality on blastocyst development after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in a sheep model

Friday, May 11, 2012
Sheep oocyte quality was assessed by brilliant cresyl blue (BCB) staining. Stained oocytes (BCB+) showed more adenosine triphosphate and more blastocysts after IVF than BCB. Differences in blastocyst percentages were not observed after ICSI.

Is there a place for corifollitropin alfa in IVF/ICSI cycles? A systematic review and meta-analysis

Thursday, May 10, 2012
We present a meta-analysis evaluating the safety and efficacy of corifollitropin alfa administration in women undergoing controlled ovarian stimulation in GnRH antagonist down-regulated IVF/ICSI treatment cycles.

Oocyte slow freezing using a 0.2–0.3 M sucrose concentration protocol: is it really the time to trash the cryopreservation machine?

Friday, May 4, 2012
We present oocyte slow-freezing outcomes using a differential sucrose concentration during dehydration (0.2 M) and rehydration (0.3 M).
