NLR and diabetic nephropathy have an independent association between them whereas there was no independent association between NLR with retinopathy in type 2 diabetic patients.

The aim of this study was to evaluate the impact of gonadotrophin therapy in combination with intracytoplasmic sperm injection (ICSI) in men with hypogonadotrophic hypogonadism (HH). Twenty-five azoospermic men were diagnosed with HH due to low FSH, LH and total testosterone concentrations. These patients were treated with human chorionic gonadotrophin for 1 month plus recombinant FSH the following month. Total testosterone concentrations were measured in the first and third months. Semen analyses were performed monthly after the third month of treatment. ICSI was performed when sperm production commenced. Total testosterone concentration and testicular volume were significantly increased after gonadotrophin therapy (P < 0.001). On average, spermatozoa were detected in the ejaculate after 10 months. Spontaneous pregnancies were achieved in four couples. Twenty-two ICSI cycles were performed in 18 couples using ejaculated or testicular spermatozoa, and 12 pregnancies (54.5% per cycle) were achieved. These results showed that HH could be treated successfully with hormonal therapy combined with ICSI using ejaculated spermatozoa. The use of ICSI made it possible to achieve pregnancy when spermatozoa appeared in the ejaculate, and shortened the duration of gonadotrophin therapy.

The hypothesis that inspection for early cleavage improves pregnancy rate by aiding selection of the best embryos for transfer was tested in this study. Inspection for early cleavage was performed randomly in women undergoing intracytoplasmic sperm injection (ICSI) cycles. No differences were observed between early cleavage-inspected and uninspected embryos. When the hypothesis that transfer of early-cleaved (EC) embryos yields a higher pregnancy rate than transfer of late-cleaved (LC) embryos was tested using early cleavage-inspected cycles, it was found that transfer of EC embryos resulted in a higher implantation rate than transfer of LC embryos. In transfers for which all embryos were EC (100% EC), transfer of fewer embryos yielded a higher implantation rate compared with LC and uninspected cycles. These results indicate that, when inspected, early cleavage increases the implantation rate in ICSI patients.

Gamete characteristics are likely to contribute to embryo development. In this preliminary study, early parameters were assessed in embryos generated following microinjection of hyaluronan-bound and unbound spermatozoa into 176 sibling oocytes, which had themselves been assessed using a polarizing light microscope imaging system. The fertilization and early cleavage rates, and day 3 embryo quality did not differ when oocytes displaying similar characteristics were inseminated with either bound or unbound sperm. Regardless of the binding characteristics of the sperm, early embryos displaying good and poor quality derived from oocytes displaying visible spindles and similar characteristics. These results indicate that early embryo developmental characteristics were independent from the hyaluronic acid binding capacity of the sperm when oocytes displayed a visible spindle.
