Correlation of Semen Analysis and Hypoosmotic Swelling Test with Subsequent Pregnancies

Hypoosmotic Sperm Swelling Test: Reevaluation of Its Potential Use

The aim of this study was to assess the predictive value of the hypoosmotic sperm swelling test. Good correlations were observed between the percentage of spermatozoa undergoing swelling and the percentage motility both in normal (r = 0.68; p < 0.001) and infertile patients (r = 0.65; p < 0.001). In contrast, sperm swelling did not significandy correlate either with sperm oocyte fusion (assesse...

Comparison between glycerol and ethylene glycol for the cryopreservation of equine spermatozoa: semen quality assessment with standard analyses and with the hypoosmotic swelling test.

The aims of this study were to compare glycerol (G) at customary concentrations and ethylene glycol (EG) as cryoprotectants for stallion semen in a skimmed milk (SM) extender, to test different EG concentrations and to compare the results of manual and computerized analysis with the hypoosmotic swelling (HOS) test. Ejaculates from two stallions were collected over 3 weeks (6 ejaculates per stal...

Previous Pregnancies and the Subsequent Risk of Knee Osteoarthritis

Background: Osteoarthritis of the knee is a major problem and one of the most causes of disability in the elderly. Woman tending to have more frequent and more severe evidence of knee osteoarthritis. Because of the possibility, that hormonal changes may influence the disease, the present study was designed to investigate the association between pregnancies and osteoarthritis of the knee. Metho...

Hypoosmotic swelling test in young Nelore bulls classified as sound and unsound for breeding

This work aimed to study the correlations between the physical characteristics of semen, sperm morphology and the biochemical integrity of the plasmatic membrane of raw sperm in young Nelore bulls (Bos taurus indicus). A total of 420 bulls between 18 and 22 months of age were examined for breeding soundness according to the criteria established by the Brazilian College of Animal Reproduction. A...
