Infertility is defined as lack of conception after at list 12 months of unprotected intercourse. For investigating and diagnosing infertile couples, semen analysis is necessary. Find out the reason of infertility is an important thing we need to do. In order to investigate harmful effects of some environmental factors, we have carried out this study. 466 semen samples in 420 male partners were analyzed basing on their jobs, we found that high ratio of azoospermia had been found in male partners who used to contact with high temperature. Low ratio of living spermatozoid had been found in male partners who used to contact with chemical substances and in the functionaries

Nowadays, there is high rate of infertile couples in population. For improving living quality, therefore some one has to take care of these couples. Infertility is defined as lack of conception after at list 12 months of unprotected intercourse. For investigating and diagnosing infertile couples, semen analysis is necessary. 446 semen samples in 420 male partners were analyzed we found that in infertile couples, 56% male partners had semen abnormality low motility 31.9%, oligospermia 16.43%, low viability 25.5%, teratozoospermia 14.05%, azoospermia 10.24%.

PURPOSE: The aim of this study was to compare sperm concentration, motility, viability, and morphology using Percoll gradient, PureSperm gradient, and the swim-up method in normal semen samples. MATERIALS AND METHODS: Ten normal semen samples were divided into three fractions. Motile sperm were isolated with Percoll gradient, PureSperm gradient, and swim-up method. Sperm concentration, motility, viability, and morphology were determined before and after separation. RESULTS: The sperm concentrations were not significantly different among the three METHODS: Percoll gradient(34.3+/-9.4x10(6)/ml), PureSperm gradient(37.6+/-16.6x10(6)/ml), and swim-up(27.3+/-6.4x106/ml). There was no significant difference in sperm motility among the three METHODS: Percoll gradient(93.5+/-1.6%), PureSperm gradient(92.7+/-4.4%), and swim-up(95.7+/-2.7%). When sperm motility was measured 24 hr later, the results were similar among the three METHODS: Percoll gradient(81.7+/-15.5%), PureSperm gradient(84.3+/-12.2%), and swim-up(89.4+/-5.1%). Sperm viability and morphology were slightly higher in swim-up method than the other methods, but the differences were not statistically significant. Sperm viability datas were: Percoll gradient(85.5+/-5.5%), PureSperm gradient(85.6+/-3.7%), and swim-up(88.6+/-6.6%). Morphology datas were: Percoll gradient(82.0+/-10.7%), PureSperm gradient(73.9+/-9.3%), and swim-up(83.7+/-8.5%). CONCLUSIONS: The swim-up method resulted in viability and morphology that were slightly higher than the other methods. However, all methods were useful for sperm preparation in normal semen samples.

Up to day, there was no definite report in hormonal changes in serum and seminal plasma which might be affected by vasectomy. In order to clarify the controversy regarding hormonal change in normal, vasectomy and vasovasostomy, author has observed LH, FSH and Testosterone in seminal plasma as follow; l. The LH and FSH level has been shown decrease comparison with control group after vasectomy 2. The LH level has been rising with vasovasostomy. 3. The FSH level was some increased after vasovasostomy, but which is not statistically significant. 4. The Testosterone has not been shown any change with vasectomy and vasovasostomy.
