Effect of seminal leukocytes on in vitro fertilization and intracytoplasmic sperm injection outcomes

Monday, June 29, 2015
Leukocytospermia (1  106 leukocytes/mL), assessed by flow cytometry, does not significantly influence IVF or ICSI outcomes. The same results were obtained by using lower or higher cut-off values for leukocytospermia (from 0.2 to 2  106/mL).

Status of sperm morphology assessment An evaluation of methodology and clinical value

Monday, December 29, 2014
Morphology levels in sperm assessments decreased over time, owing to changes in methodological factors, and male aging. No prognostic value was found for individual in vitro fertilization or intracytoplasmic sperm injection patients.

Assessment of follicular fluid leptin levels and insulin resistance as outcome predictors in women undergoing in vitro fertilization intracytoplasmic sperm injection

Tuesday, November 25, 2014
High follicular fluid leptin levels were associated with a lower probability of live birth in women undergoing in vitro fertilization–intracytoplasmic sperm injection. Serum progesterone, follicle number, and leptin levels seem to predict IVF outcome.

Assisted hatching and intracytoplasmic sperm injection are not associated with improved outcomes in assisted reproductive technology cycles for diminished ovarian reserve An analysis of cycles in the United States from 2004 to 2011

Friday, June 27, 2014
In initial assisted reproduction cycles for which the only diagnosis is diminished ovarian reserve, the practices of assisted hatching and intracytoplasmic sperm injection are not associated with improved live birth rates.

Normal live births after intracytoplasmic sperm injection in a man with the rare condition of Eagle Barrett syndrome prune belly syndrome

Wednesday, November 27, 2013
Intracytoplasmic sperm injection (ICSI) with sperm from a man with Eagle-Barrett syndrome (EBS) resulted in the births of two normal healthy male infants, suggesting that EBS is not transmitted to male offspring.
