Background:
In many diabetic patients, spermatogenesis complications are frequent causing infertility problems. This study aimed to demonstrate the effect of Forskolin on male reproductive dysfunction caused by type 2 diabetes.
Materials And Methods:
In this experimental study, type 2 diabetes was induced by a high-fat diet (HFD) for one month and then a low single dose injection (35 mg/kg) of streptozotocin (STZ) in Wistar rats. After 72 hours, rats with more than 200 mg/dl of blood glucose were considered type 2 diabetic rats. Forty rats (200-250 g) were divided into four groups (n=10) including group 1 (G1): rats with normal diet and buffer citrate (STZ solvent) injection, group 2 (G2): control type 2 diabetic rats with HFD and STZ injection, group 3 (G3): type 2 diabetic rats received phosphate buffer saline (PBS) as Forskolin solvent, and group 4 (G4): Forskolin treated diabetic rats (10 mg/kg) for 1 month.
Results:
In comparison to control group, in diabetic groups (G2 and G3) some parameters are increased significantly: The blood glucose (P=0.00078), testicular malondialdehyde (MDA) level and body weight (P=0.00009) and Bax gene expression (P=0.00007). Unlike, some parameters are decreased significantly: The serum level of testosterone (P=0.0009), testicular superoxide dismutase (SOD, P=0.00007) and glutathione peroxidase (GPX) levels (P=0.00008), sperm concentration (P=0.00008), motility (P=0.00009), normal morphological sperm (P=0.00008) and Bcl-2 gene expression (P=0.00009). However, in Forskolin treated group (G4) the parameters stayed close to control values that was significantly (P=0.00007) higher than in G2 and G3 groups. Therefore, treatment with Forskolin significantly improved these abnormal changes in Forskolin-treated group.
Conclusion:
Our study demonstrates that Forskolin is an effective antidiabetic agent, which significantly improves sperm concentration, testosterone levels, and antioxidant activity in diabetic rats.
Insights
Forskolin effectively combats male infertility in type 2 diabetes by improving sperm health and testosterone levels. This study shows Forskolin significantly reverses diabetes-induced reproductive dysfunction in rats.
Area of Science:
- Reproductive Biology
- Endocrinology
- Diabetology
Background:
- Type 2 diabetes frequently causes male infertility due to spermatogenesis complications.
- Male reproductive dysfunction is a significant concern in diabetic patients.
Purpose of the Study:
- To investigate the therapeutic effects of Forskolin on type 2 diabetes-induced male reproductive dysfunction.
- To evaluate Forskolin's impact on key reproductive parameters and oxidative stress markers in diabetic rats.
Main Methods:
- Type 2 diabetes was induced in Wistar rats using a high-fat diet and streptozotocin (STZ).
- Diabetic rats were treated with Forskolin (10 mg/kg) for one month.
- Key parameters including blood glucose, testosterone levels, sperm parameters, oxidative stress markers (MDA, SOD, GPX), and gene expression (Bax, Bcl-2) were analyzed.
Main Results:
- Diabetic rats exhibited significantly increased blood glucose, body weight, and MDA levels, alongside decreased testosterone, sperm quality, and antioxidant enzyme activity.
- Forskolin treatment (G4) normalized these parameters, bringing them closer to control group levels.
- Forskolin significantly improved sperm concentration, motility, morphology, testosterone levels, and antioxidant status in diabetic rats.
Conclusions:
- Forskolin demonstrates significant efficacy as an antidiabetic agent in improving male reproductive health.
- The study highlights Forskolin's potential to reverse diabetes-associated infertility by enhancing sperm parameters and testosterone production.
- Forskolin treatment effectively mitigates oxidative stress and modulates apoptosis-related gene expression in diabetic testes.
