Swim-up method significantly reduces sperm DNA fragmentation rates and may have some prognostic value on intrauterine insemination in patients with decreased sperm DNA integrity.

In this study, our objective was to evaluate the impact of testicular histopathology on the outcome of intracytoplasmic sperm injection (ICSI) cycles of patients with nonobstructive azoospermia and correlate with clinical and hormonal parameters. For this purpose, 271 patients with nonobstructive azospermia (NOA) who underwent testicular sperm extraction (TESE) for ICSI cycles were retrospectively evaluated for sperm retrieval, fertilisation, embryo cleavage, clinical pregnancy and live birth rates among different testicular histology groups. We also correlated hormonal and clinical factors with histological findings. Sperm retrieval and fertilisation rates (FR) were found to be significantly different among all testicular histological groups of NOA except for embryo cleavage, clinical pregnancy and live birth rates. Furthermore, serum follicle stimulating hormone (FSH) level was the most significant variable to predict sperm recovery on TESE. Separate analyses within each testicular histological group revealed that higher FSH was also associated with lower pregnancy rates in only maturation arrest group. In conclusion, testicular histology significantly influences sperm retrieval and FRs but not pregnancy and live birth rates in nonobstructive azoospermia. However, FSH is the best predictor of a successful TESE.

In this study, our objective was to evaluating the value of serum zinc levels as an etiologic and prognostic marker in patients with polycystic ovarian syndrome. We conducted a prospective study, including 53 women with polycystic ovarian syndrome and 33 healthy controls. We compared serum zinc levels, as well as clinical and metabolic features, of the cases. We also compared serum zinc levels between patients with polycystic ovarian syndrome with insulin resistance. Mean zinc levels were found to be significantly lower in patients with polycystic ovarian syndrome than healthy controls. Multiple logistic regression analysis of significant metabolic variables between polycystic ovarian syndrome and control groups (serum zinc level, body mass index, the ratio of triglyceride/high-density lipoprotein cholesterol, and homocysteine) revealed that zinc level was the most significant variable to predict polycystic ovarian syndrome. Mean serum zinc levels tended to be lower in patients with polycystic ovarian syndrome with impaired glucose tolerance than patients with normal glucose tolerance, but the difference was not statistically significant. In conclusion, zinc deficiency may play a role in the pathogenesis of polycystic ovarian syndrome and may be related with its long-term metabolic complications.

Intrahepatic cholestasis of pregnancy (ICP) is an uncommon disorder, which generally occurs in the second and third trimester of pregnancy with symptoms of pruritus. The cause of ICP is unknown but genetic, hormonal and environmental factors contribute to its pathogenesis. The aetiology of ICP is unclear but elevation in oestrogen levels thought to cause ICP is typically seen in the third trimester of pregnancy, and for this reason it is not usually considered in the differential diagnosis of pruritus and liver function disorders in the first trimester of the pregnancy. We present two cases of pregnancy after IVF treatment diagnosed with ICP following the development of OHSS, deteriorating liver function tests and severe pruritus.
