Gonadorelin is another name for gonadotropin-releasing hormone (GnRH). It is a synthetic decapeptide prepared using solid phase peptide synthesis. GnRH is responsible for the release of follicle stimulating hormone and leutinizing hormone from the anterior pitutitary.
GnRH is available as gonadorelin hydrochloride(Factrel)and gonadorelin diacetate tetrahydrate(Cystorelin)for injectable use. Studies have described it being used via an infusion pump system to induce ovulation in patients with hypothalamic hypogonadism. It is also used in veterinary medicine as a treatment for cattle with cystic ovarian disease.
Gonadorelin is responsible for the release of follicle stimulating hormone and leutinizing hormone from the anterior pitutitary. In the pituitary GnRH stimulates synthesis and release of FSH and LH, a process that is controlled by the frequency and amplitude of GnRH pulses, as well as the feedback of androgens and estrogens.
The pulsatility of GnRH secretion has been seen in all vertebrates, and it is necessary to ensure a correct reproductive function. Thus a single hormone, GnRH, controls a complex process of follicular growth, ovulation, and corpus luteum maintenance in the female, and spermatogenesis in the male. Its short half life requires infusion pumps for its clinical use.

How do you practice pull-ups at home? How to practice without a pole in the pull-ups?
We often say that squat is the king of action, and when considering the upper body, I want to give this crown to the pull-ups.
Pull-ups can exercise most of our upper body muscles, back muscles (latissimus dorsi muscle, rhomboid muscle), arms (two heads and three heads, forearms, grip strength), deltoids and chest muscles
In addition to so many muscle groups, the pull-ups also need very good core strength to support the movement, so it is no exaggeration to say that it is the king of upper body training!
There are many ways to perform the pull-ups, and there are many variations. Usually you only need a fixed horizontal bar!
However, for many people, there is no way to have a bar at any time and place. It is best if you can do pull-up training at home. There is nothing to pull, let yourself keep up to date!
Today, I will introduce you to a very good little trick. You don't need a bar. You only need two towels, you can pull up at home at any time!
Step 1: Choose two towels and tie the knot at one end of the towel.
Step 2: Hang the tied towel on the door
Step 3: close the door, the towel is stuck in the back of the door, avoid sliding
Step 4: Finish, start the pull-up
