Effects Of Steroid 17-Methyltestosterone Powder On Sex Reversal In Fish Tilapia Aquaculture

What Is 17-Methyltestosterone Powder?

17- Methyltestosterone powder is a synthetic anabolic-androgenic steroid (AAS) and progestogen. It is a methylated derivative of testosterone and is also known as methyltestosterone. It is used as a male sex hormone supplement. Methyltestosterone treats hypogonadism in males, delayed puberty in males, and breast cancer in females. People are widely using it as a performance-enhancing drug (PED). It is often used to treat low testosterone levels in men. It can also be used to improve body composition and increase muscle mass.

17-Methyltestosterone powder is a potent anabolic steroid. It is used to gain muscle mass and strength in athletes. 17-Methyltestosterone Powder can be injected, but it is also available in a pill or tablet form. Depending on the manufacturer’s preference, the Powder comes in either red or white. 17-Methyltestosterone Powder has been around since the 1950s and has been a popular steroid today because it offers many benefits to those who use it responsibly. By using this steroid properly, you will experience unmatched gains in strength and size. The starting dose is 10 mg to 20 mg per day for men. Women typically start with 5 mg to 10 mg per day. Methyltestosterone should not be used for more than 12 weeks.

17-Methyltestosterone Powder can stimulate the growth of male characteristics and sex organs in female animals, but in high doses, it can also cause masculinisation of female animals. 17-Methyltestosterone Powder can promote the growth of male sexual organs and secondary sexual characteristics in female animals and can also promote the growth of female sexual organs and promote the development of sexual features.


Effects Of 17-Methyltestosterone Powder On Sex Reversal In Tilapia Aquaculture

17-Methyltestosterone is a synthetic anabolic-androgenic steroid (AAS) and derivative of testosterone. It is used in aquaculture to sex-reversed tilapia, making them male. This results in all-male tilapia populations, which grow faster and are more resistant to disease than mixed-sex populations. 17-Methyltestosterone powder also causes some masculinisation in female tilapia, resulting in fish with smaller ovaries and less egg production.

In tilapia aquaculture, using 17-methyltestosterone (MT) to reverse the sex of fish is familiar. The study aimed to investigate MT’s effects on the sex reversal of tilapia. Sixty fish were randomly divided into three groups: a control group, a group treated with MT, and a group treated with MT and progestin. The fish were treated with MT at ten mg/L for ten days. The fish in the MT and the MT+P groups were treated with MT for ten days and then with progestin for an additional ten days. The expression of the gene was analysed using real-time PCR. The results showed that the mRNA levels of cyp19a1a and 17?-HSD3 were significantly increased in the MT group compared with the control group (p < 0.05). The mRNA level of 17?-HSD2 was boosted considerably in the MT+P group compared with the control group (p < 0.05). The mRNA level of amh was decreased significantly in the MT group compared with the control group (p < 0.05). The mRNA level of sox9 was increased dramatically in the MT group.
