TL;DR: The presence of T-mycoplasmas in semen specimens from 625 men with infertility of unknown etiology was correlated with seminal cytologic findings as mentioned in this paper, and a change in the distribution toward higher ejaculate volumes and lower counts was demonstrated in the 246 patients with positive Tmycplasma cultures, compared with the 379 patients with negative cultures.

TL;DR: It was determined that cervical mucus does serve as a reservoir for those sperm which are transported to the Fallopian tubes and was related to time from insemenation.
55 citations
TL;DR: A positive relationship between the different variables, sperm density and sperm motility (in percentage of motile sperm and degree of forward motion), as well as between the two variables of sperm motability and sperm morphology to the other variables was confirmed.

TL;DR: Synthetic luteinizing hormone-releasing hormone appears to be of value in the treatment of certain types of oligospermia, but several issues remain unsettled.

TL;DR: The concentration of prostaglandin E (PGE) was measured in the semen of 5 men of proven fertility and in 12 men of couples who were infertile but in whom no abnormality had been detected by conventional semen analysis, postcoital test of sperm motility, endometrial biopsy, and laparoscopic dye insufflation of the fallopian tubes.

TL;DR: All semen characteristics, with the exception of pH, were significantly influenced by season and the semen quality of the Iraqi breed was similar to that of the New Hampshire breed.
Abstract: 1. The effects of season, temperature, humidity and light on semen volume, pH, concentration, motility and the proportions of dead and abnormal spermatozoa were investigated on White Leghorn, New Hampshire and Iraqi cockerels. 2. All semen characteristics, with the exception of pH, were significantly influenced by season. 3. The semen quality of the Iraqi breed was similar to that of the New Hampshire breed.

TL;DR: The results from 225 men attending an infertility clinic are presented and the percentage of oval, viable and active sperm cells, and the motility scores were lower in samples with counts, while viscosity problems seemed to be associated with counts less than 10 times 10(6) per ml.

TL;DR: The seminal plasma from the boars after surgery compared with normal litter mates had a more watery consistency and did not form the characteristic gelduring ejaculation, while the sperm concentration was lower and the total reduction of sperm number ejaculate was 78% in the experimental animals.
Abstract: A technique for the removal of the seminal vesicles from boars was developed and the effects on semen characteristics were studied. The surgical technique was carried out on 12 animals; 6 of these were subsequently trained for semen collection. Removal of the glands was shown to be completely successful in 9 of the animals. Following surgery the seminal plasma had a more watery consistency and did not form the characteristic gel after ejaculation. Whole ejaculate volume and sperm concentration were significantly lower (p less than .05 and p less than .01 respectively) after removal of the seminal vesicles; however the ratio of living to dead spermatozoa remained unchanged. Citrate and protein concentrations were also significantly depressed (p less than .01). Semen pH increased (p less than .01) and osmolarity remained unchanged. Semen from experimental boars used in the insemination of gilts revealed no marked loss of fertility compared with the controls and no regeneration of the seminal vesicles was seen when animals were slaughtered up to 17 months postsurgery.

TL;DR: The normal range in men with proven fertility was 90 to 260 mug/ml of 19-hydroxy Es and 30-200 mug/ML of Es.

TL;DR: Non-motile sperm cells in seminal analyses was the most common finding in both series 2 weeks after vasectomy and 2 months postoperatively, however, two azoospermic semen analyses must be obtained before sterility after Vasectomy can be ascertained.
Abstract: The effect of irrigation of vasa deferens on the postvasectomy semen content of 70 men was determined. To avoid recanalization the cut ends of the vasa were sutured in different fascial planes. In 20 other cases the distal ends of the vasa were also irrigated with 20 cc of the highly acid Kystosol solution before suturing. 2 weeks later only 1 patient sh owed azoospermia after vasectomy alone and only 5 after vasectomy plus t he irrigation. Nonmotile sperm were found in 42 cases among the vasectomy-alone group and in 15 cases in the irrigated group. In the vasectomy-alone group motile sperm cells were found in 27 patients but no motile sperm cells in the irrigated patients. 2 months after vasectomy absence of spermatozoa was noted in 31 (44%) patients following vasectomy alone and in 18 patients (90%) after added irrigation. In 2 instances motile cells were still present in vasectomy-alone patients. 3 months postvasectomy 64 (91%) of the vasectomy-alone group were azoospermic and all of the irrigation group. At 4 months all except 1 were azoospermic. This patient was later shown to have recanalization of a vas. It is concluded that although irrigation of the vasa deferens with Kystosol solution facilitates the disappearance of sperm cells from ejaculates after vasectomy 2 totally azoospermic semen analyses are needed to assure sterility.

TL;DR: This method is easily and quickly performed and can therefore be used as a routine method for the determination of sperm agglutinating antibodies and its application for sperm-immobilizing or cytotoxic activity remains to be tested.
Abstract: A new technique by which sperm antibodies are purified by affinity-chromatography in a batch device and the sperm agglutinating activity controlled by the Franklin and Dukes (FD) test is described. Specific absorption takes place on an insoluble antigen and desorption reveals purified antibodies. In sera of women with unexplained infertility which were found to be positive to the FD test a specific globulin binding takes place. For quantitative detection of these purified antibodies crossed immunoelectrophoresis was done. Sera of 4 such infertile women were used. Uterine cervical mucus samples of 3 of them were also examined. As controls sera negative to the FD test and cervical mucus from the same patients were processed. Spermatozoa were obtained from 15 donors pooled washed 3 times with phosphate-buffered saline and adjusted to spermatozoa content. Cervical mucus was also prepared. Techniques used are given. The method can be easily and quickly performed and therefore used routinely. Antibody fractions purified by affinity-chromatography migrating against an AHS-containing gel demonstrated 1 big peak in all 4 of the FD-positive semen samples as well as in the 3 cervical mucus samples. The height of the peak represented a nearly linear relation to the sperm antibody content of the semen. Control samples never showed this peak. By absorption experiments it was found that the protein encountered in serum is IgM and that in cervical mucus IgA. The content of antibodies in the cervical mucus of the same woman was about 1/10 smaller than in her serum. This method is stated to be an improvement over other techniques. Some sperm antibodies are not of the agglutinating type.
