The effects of Carica papaya juice on sperm's quality in obese rats / Nurliyana Khairul Kamal

Obesity is one of the leading causes of death worldwide. Fortunately, Carica papaya has been traditionally used to treat obesity problem. Being obesity accused to be one of the reasons of infertility. The objectives of this research are to determine the effect of Carica papaya juice uptake on sperm quality (sperm count, sperm morphology, sperm motility, sperm viability) and to determine the anti-obesity properties of Carica papaya juice on rat's body weight. 15 rats will be divided into three groups of five rats.The groups are; normal group, papaya group and obesity group. All rats were purchased at the same age and weight around 150 g. Rats in treatment and obesity group were put on weight by ingesting food pellets covered with butter. Next, Carica papaya juice were given to the papaya group for three weeks. Sperms from epididymis were collected for its quality assessment. The parameters assessed included sperm count, sperm morphology, sperm motility and sperm viability were observed under a light microscope. According to the results, sperm morphology showed negative results and none of the sperm analysis data were significant (p > 0.05). For sperm motility of papaya group, fast progressive is 5.48%, slow progressive is 1.00%, non-progressive is 5.00% and immotile is 67.00%. For sperm viability, viable sperm is 74.40% while non-viable sperm is 25.60%. Sperm concentration of papaya group is 6.60 millions/mL while percentages of normal and abnormal sperm were 40.70% and 59.30% respectively. On the other hand, Carica papaya proved to has anti-obesity properties as it was able to decrease rat's body weight gained by 2.66 g after three weeks with p > 0.05.
