Menotropin preparations are designed for use in selected women where they stimulate the ovaries to mature follicles, thus making them more fertile. They are administered by typically daily injection, intramuscularly or subcutaneously, for about ten days under close supervision to adjust dose and duration of therapy.
Gonadotropin preparations are drugs that mimic the physiological effects of gonadotropins, used therapeutically mainly as fertility medication for ovarian hyperstimulation and ovulation induction. [1] For example, the so-called menotropins consist of LH and FSH extracted from human urine from menopausal women. [2] There are also recombinant ...
XX gonadal dysgenesis is a type of female hypogonadism in which the ovaries do not function to induce puberty in a person assigned female at birth, whose karyotype is 46,XX. [1] Individuals with XX gonadal dysgenesis have normal-appearing external genitalia as well as Müllerian structures (e.g., cervix, vagina, uterus).
Why does ovarian hyperstimulation syndrome occur? OHSS is a potential side effect of stimulating the ovaries to produce multiple eggs at the same time either during the first part of an IVF cycle ...
Gonadotropins are glycoprotein hormones secreted by gonadotropic cells of the anterior pituitary of vertebrates. [1] [2] [3] This family includes the mammalian hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), the placental/chorionic gonadotropins, human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG), [3] as well as at least two forms of fish ...
Primary Ovarian Insufficiency: Ovaries fail to properly function before 40 years of age, causing a decrease in estrogen levels. [6] [8] [9] Ovarian Failure due to Radiation or Arterial Embolization: These treatments involve radiation or embolization of the ovaries and can cause ovarian damage. This leads to decreased estrogen production and ...
The HPG axis plays a critical part in the development and regulation of a number of the body's systems, such as the reproductive and immune systems. Fluctuations in this axis cause changes in the hormones produced by each gland and have various local and systemic effects on the body. The axis controls development, reproduction, and aging in ...
Hypoestrogenism is most commonly found in women who are postmenopausal, have primary ovarian insufficiency (POI), or are presenting with amenorrhea (absence of menstrual periods). Hypoestrogenism includes primarily genitourinary effects, including thinning of the vaginal tissue layers and an increase in vaginal pH.
