Linear and non-linear relationships between the 'swelling test' and conventional semen variables in men suspected of primary infertility

The relationship and degree of association between the percentage of sperm swelling (HOS-test) and conventional semen variables was investigated in 263 consecutive ejaculates. The semen samples were exclusively obtained from men suspected of primary infertility. It was found that the correlation coefficients (Spearman's rho) followed the order: percentage of progressive motility at 3 h greater than count/ml greater than percentage of total motility at 3 h greater than percentage of normal spermatozoa. Of the three morphology sub-classes considered (sperm head, mid-piece and tail abnormalities), only mid-piece abnormalities correlated with the outcome of the HOS-test (rho = -0.409). Linear relationships between HOS-test results and sperm motility and morphology, but not sperm count, were indicated by LOWESS-smoothing. However, a linear relationship between the HOS-test, sperm count and a 'functional index' combining the conventional semen variables could be demonstrated after normalization of the data. Our findings suggest that the HOS-test may be of value in assessing the functional integrity and viability of spermatozoa; however, its prognostic power for fertility is probably not different from that of conventional semen variables.

Increased frequency of congenital chromosomal aberrations in female partners of couples undergoing intracytoplasmic sperm injection

We evaluated the frequency of congenital chromosomal aberrations in a sample of 305 couples included in an intracytoplasmic sperm injection (ICSI) programme. Twenty individuals (3.3%) with congenital chromosomal abnormalities could be identified. The following types of abnormalities were observed: reciprocal translocations (n = 7), Robertsonian translocations (n = 3), inversions (n = 3), other structural aberrations (n = 4) and sex chromosome aberrations (n = 3). The rate of chromosomally abnormal males (10/305, 3.3%) lay within the expected range for patients with reduced semen quality. Surprisingly, 50% (10/20) of all abnormal karyotypes were contributed by the female partner of ICSI patients. These data confirm the higher incidence of chromosomal aberrations in infertile populations as compared with the baseline population risk. Additionally, the data imply that in some cases of male factor infertility a hidden female chromosomal factor may be present, which cannot be identified by standard clinical evaluation. In conclusion, we recommend chromosomal analysis in both partners of couples undergoing ICSI treatment.

Increased levels of sperm ubiquitin correlate with semen quality in men from an andrology laboratory clinic population

BACKGROUND: Ubiquitin, a house-keeping protein that marks other proteins for proteasomal degradation, tags defective sperm during epididymal passage. To establish ubiquitin as a biomarker of human infertility, the present study examines the relationships between sperm ubiquitin content and clinical semen parameters among men from an infertility clinic population with varied aetiologies. METHODS: Anti-ubiquitin immunoreactivity was measured by flow cytometric sperm-ubiquitin tag immunoassay (SUTI) in sperm samples of 28 infertility patients and 15 fertile donors. Semen analyses were performed by computer-assisted semen analysis and World Health Organization morphology. RESULTS: Median values of ubiquitin-induced fluorescence had a strong negative correlation with sperm count (r = -0.63, P = 0.0003) and a positive correlation with % abnormal morphology (r = 0.55, P = 0.01). Infertility patients (n = 28) had significantly higher levels of sperm ubiquitin. Out of 28 patients, six reported possible occupational exposures to solvents, three were current smokers and six were ex-smokers. Within the patient group, men with known male factor infertility, those with self-reported occupational exposure to solvents and current smokers had the highest sperm ubiquitin levels. When men with jobs involving potential occupational exposure to solvents were combined with current smokers, the highest correlations were found between sperm ubiquitin and motility (r = -0.74), count (r = -0.82) and % sperm abnormalities (r = 0.73). CONCLUSIONS: Increased sperm ubiquitin was inversely associated with sperm count, motility and % normal morphology, supporting the use of ubiquitin as a biomarker of human semen quality. SUTI assay confirmed poor semen quality in all men with poor clinical semen parameters, but also was high in some patients with seemingly good clinical semen parameters. Occupational exposure to solvents and smoking may have contributed to high levels of sperm ubiquitin in some of these patients.
