R-follicle stimulating hormone (r-FSH), also known as recombinant follicle stimulating hormone, is a medication that mimics a natural hormone called follicle-stimulating hormone (FSH) produced by the pituitary gland [1].
Here's a breakdown of r-FSH:
- Function:
- Stimulates the development of follicles in ovaries (females) and sperm production in testes (males) [1, 2].
- Uses:
- In females: Treatment of infertility caused by ovulation problems or used in conjunction with assisted reproductive technologies (ART) like in-vitro fertilization (IVF) to stimulate egg development [1, 3].
- In males: Treatment of infertility due to low sperm production [2].
- Form:
- Produced through recombinant DNA technology in a lab [1]. This means scientists create a genetic blueprint for FSH and introduce it into host cells, which then produce the hormone.
- Administered as an injection under the skin [1].
Important things to know about r-FSH:
- It should only be used under the supervision of a doctor who specializes in fertility treatment [1].
- There can be side effects associated with r-FSH use, including ovarian hyperstimulation syndrome (OHSS) in females and enlarged testicles or breast tissue in males [1].
- It's not suitable for everyone and may not be recommended for people with certain medical conditions [1].
