TL;DR: Marked improvement occurs in sexual performance, semen analysis and testicular biopsy after successful kidney transplantation, and Immunosuppressive treatment, at dosages used six months after allografting, does not appear to affect male fertility adversely.
Abstract: Spermatogenesis has been studied in eight chronic uremic patients on hemodialysis and in 11 recipients of well-functioning renal allografts. Sexual activity, semen analysis and testicular biopsy are abnormal in chronic uremic patients. Spermatogenesis remains "arrested" even when uremia is well controlled by intermittent hemodialysis. Marked improvement occurs in sexual performance, semen analysis and testicular biopsy after successful kidney transplantation. Immunosuppressive treatment, at dosages used six months after allografting, does not appear to affect male fertility adversely.

TL;DR: In this case-control study, bicycle taxi operators had lower semen volume, concentration, total motility, and progressive motility as well as a higher concentration of abnormally shaped spermatocytes, compared to healthy controls.
Abstract: Aim The purpose of this study was to evaluate the semen profiles of bicycle taxi cyclists and healthy controls in Mangochi district, Malawi. Methods Semen samples were collected from young bicycle taxi cyclists after two to three days of sexual abstinence. A control group, comprising young men who were not bicycle taxi operators also submitted semen samples. Samples were left to liquefy for 30 minutes before measurements were conducted of volume, concentration, total motility, and progressive motility. This was followed by preparation of morphology slides. Light microscopy was used for sperm analysis. Results Semen parameters such as volume (1.66 ± 0.18 mL vs. 3.64 ± 0.17 mL; p = 0.0001), concentration (28.31 ± 4.33 x 106/mL vs. 54.95 ± 5.93 x 106/ mL; p = 0.02) , total motility (56.98% ± 8.22% vs. 56.98% ± 8.22%; p = 0.03), progressive motility (22.57% ± 3.35% vs. 59.69% ± 4.82%; p = 0.004), and morphology (6.98% ± 3.23% vs. 19.73% ± 2.32%; p = 0.006) were significantly reduced in the bicycle taxi cyclists compared to the healthy controls. Conclusion In this case-control study, bicycle taxi operators had lower semen volume, concentration, total motility, and progressive motility, as well as a higher concentration of abnormally shaped spermatocytes, compared to healthy controls.
