- Abstract
Recent studies have demonstrated that hypothyroidism is associated with infertility. This work was undertaken to evaluate the protective effects of Aframomum melegueta on testicular functions and fertility of hypothyroid male rats. Male rats were orally treated with propylthiouracil (PTU: 10 mg/kg) in combination with plant aqueous or methanol seed extract (20 and 100 mg/kg) for 56 days. Vitamin E and clomiphene citrate served as positive controls. On day 47 of treatment, each male was mated with two adult females for fertilization potential evaluation. At the end of the treatment, genital sex organ weights, sperm characteristics, testicular histology, oxidative status, plasmatic hormones and fertility potential were evaluated. Results indicated that PTU created hypothyroidism characterised by a significant increase in TSH with reduction of T3 and T4. PTU also lowered genital sex organ weights, sperm count, viability and motility, plasmatic levels of luteinising hormone, follicle‐stimulating hormone and testosterone, and increased prolactin, cholesterol and testicular oxidative stress. Alteration in sperm morphology, testis and epididymis histology, and fertilization potential was also noticed. Co‐administration with A. melegueta extracts successfully reversed PTU‐induced infertility without any effect on thyroid hormones. These results provide evidence that A. melegueta has a protective effect on fertility in hypothyroid condition.
