Materials and methods: Totally, 28 patients with thyroid disorders were evaluated for the semen parameters. Serum TSH and T4 concentrations were measured by ELISA. Complete semen analyses were performed based on WHO. Results: Pathozoospermia was seen in 32.14% of our patients. Two hyperthyroid patients and seven hypothyroid patients suffered sperm defects. None of pathozoospermia patients showed an alone sperm defects. Sperm multiple anomalies were our main findings. Conclusion: It seems that sperm characterizes strongly were affected. Although, we have a limited sample size, but sperm multiple abnormalities made our interest findings. }, URL = {http://jbrms.medilam.ac.ir/article-1-354-en.html}, eprint = {http://jbrms.medilam.ac.ir/article-1-354-en.pdf}, journal = {Journal of Basic Research in Medical Sciences}, doi = {10.29252/jbrms.5.1.47}, year = {2018} }
