RESUMEN

The sperm chromatin structure assay (SCSA) has been proposed as a useful addition to the battery of tests routinely used to explore semen quality and hence to give an indication of the likelihood of a successful pregnancy. As usually performed at present, the assay yields two main sperm variables, the DNA fragmentation index (DFI) and the high DNA stainability (HDS). In the present study 275 patients undergoing 215 in vitro fertilization (IVF) and 215 intracytoplasmic sperm injection (ICSI) cycles were studied with the purpose of defining the clinical significance of HDS in IVF and ICSI cycles. Using the Spearman correlation test there were no significant statistical relationships between %HDS and fertilization rate, rate of embryo growth, blastocyst rate, implantation rate, or live birth rate. Rate of pregnancy loss showed a negative relationship significant at the 0.05 level which is unexplained. It is not known whether the normal practice of using processed sperm for fertilization plays any part in this lack of a negative effect of HDS level upon the stages of the cycle. A total of 16 patients with HDS levels >28% had an average live birth rate of 47.8% and an average pregnancy loss of 8.7%, which compared favourably with the group of patients as a whole.

RESUMEN

High-resolution transvaginal ultrasound has facilitated the diagnosis of adenomyosis. This study determined the prevalence of this finding in infertile women and its effect on the outcome of IVF/intracytoplasmic sperm injection (ICSI). This prospective study evaluated 275 consecutive women, commencing IVF/ICSI for the first time. Inclusion criteria were adequate ovarian reserve. Women with fibroids or a previous myomectomy were excluded. All women were screened for adenomyosis by transvaginal ultrasound on three separate occasions. The control group included 256 women and the adenomyosis group included 19 women. There was no significant difference in the ages of women, FSH, cause of infertility, body mass index, total dose of gonadotrophin used and number of oocytes collected between the two groups. However, women with adenomyosis had a higher mean antral follicle count (P=0.006). The clinical pregnancy rate (22.2% versus 47.2%) and ongoing pregnancy rate (11.1% versus 45.9%) were significantly lower in women with adenomyosis and the miscarriage rate (50.0% versus 2.8%) was significantly higher in women with adenomyosis (all P<0.001). Ultrasound evidence of adenomyosis is found in a significant number of women presenting with infertility and has a negative impact on the outcome of IVF/ICSI. This paper suggests that a common condition known as adenomyosis is associated with a reduced success following fertility treatment such as IVF. The diagnosis of adenomyosis has been greatly facilitated by the advent of high-resolution transvaginal ultrasound. This was a study including 275 consecutive women who were commencing IVF for the first time. Comparing women who did not have adenomyosis and those that did, the clinical and ongoing pregnancy rates were both lower in women with adenomyosis (22.2% versus 47.2% and 11.1% versus 45.9%, respectively). So, fewer women with adenomyosis became pregnant and had an ongoing pregnancy. The miscarriage rate was higher in women with adenomyosis compared with those without (50.0% versus 2.8%). We conclude that ultrasound evidence of adenomyosis is found in a significant number of women presenting with infertility and has a negative impact on the outcome of IVF.
