Question: Which female sex hormone, is Deslorelin acetate known to taper off?

Context paragraphs:
Estrogen: Estrogen (American English) or oestrogen (British English) is the primary female sex hormone as well as a medication.  It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. "Estrogen" may also refer to any substance, natural or synthetic, that mimics the effects of the natural hormone.  The estrane steroid estradiol is the most potent and prevalent endogenous estrogen, although several metabolites of estradiol also have estrogenic hormonal activity.  Estrogens are used as medications as part of some oral contraceptives, in hormone replacement therapy for postmenopausal, hypogonadal, and transgender women, and in the treatment of certain hormone-sensitive cancers like prostate cancer and breast cancer.  They are one of three types of sex hormones, the others being androgens/anabolic steroids like testosterone and progestogens like progesterone.

Sex hormone receptor: The sex hormone receptors, or sex steroid receptors, are a group of steroid hormone receptors that interact with the sex hormones, the androgens, estrogens, and progestogens.  They include the:

Estriol: Estriol (E3), also spelled oestriol, is a steroid, a weak estrogen, and a minor female sex hormone.  It is one of three major endogenous estrogens, the others being estradiol and estrone.  Levels of estriol in women who are not pregnant are almost undetectable.  However, during pregnancy, estriol is synthesized in very high quantities by the placenta and is the most produced estrogen in the body by far, although circulating levels of estriol are similar to those of other estrogens due to a relatively high rate of metabolism and excretion.  Relative to estradiol, both estriol and estrone have far weaker activity as estrogens.  Although it is less commonly used than other estrogens, estriol is available for medical use throughout the world in a variety of formulations, including for oral and vaginal administration.

Estradiol: Estradiol (E2), also spelled oestradiol, is a steroid, an estrogen, and the primary female sex hormone.  It is named for and is important in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is essential for the development and maintenance of female reproductive tissues such as the breasts, uterus, and vagina during puberty, adulthood, and pregnancy, but it also has important effects in many other tissues, including bone, fat, skin, liver, and the brain.  While estrogen levels in men are lower compared to those in women, estrogens have essential functions in men, as well.  It is found in most vertebrates and crustaceans, insects, fish, and other animal species.

Sex steroid: Sex steroids, also known as gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate androgen or estrogen receptors.  Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast nongenomic mechanisms through membrane-associated receptors and signaling cascades.  The term sex hormone is nearly always synonymous with "sex steroid".  The polypeptide hormones luteinizing hormone, follicle-stimulating hormone and gonadotropin-releasing hormone are usually not regarded as sex hormones, although they play major sex-related roles.

Female sex tourism: Female sex tourism is sex tourism by women who travel intending to engage in sexual activities with a sex worker.  Female sex tourists may seek aspects of the sexual relationship not shared by their male counterpart, such as perceived romance and intimacy.  Women – especially wealthy, single, older white women – plan their holidays to have romance and sex with a companion who knows how to make them feel special and give them attention.  The prevalence of female sex tourism is significantly lower than male sex tourism.

GPER: G protein-coupled estrogen receptor 1 (GPER), also known as G protein-coupled receptor 30 (GPR30), is a protein that in humans is encoded by the "GPER" gene.  GPER binds to and is activated by the female sex hormone estradiol and is responsible for some of the rapid effects that estradiol has on cells.

Estrone: Estrone (E1), also spelled oestrone, is a steroid, a weak estrogen, and a minor female sex hormone.  It is one of three major endogenous estrogens, the others being estradiol and estriol.  Estrone, as well as the other estrogens, are synthesized from cholesterol and secreted mainly from the gonads, though they can also be formed from adrenal androgens in adipose tissue.  Relative to estradiol, both estrone and estriol have far weaker activity as estrogens.  Previously, estrone was available as an injected estrogen for medical use, but it is now no longer marketed.

Pregnenolone acetate: Pregnenolone acetate (brand names Antofin, Previsone, Pregno-Pan), also known as pregn-5-en-3β-ol-20-one 3β-acetate, is a synthetic pregnane steroid and an ester of pregnenolone which is described as a glucocorticoid and as a skin-conditioning and skin anti-aging agent.  It has been found to significantly reduce wrinkles in elderly women when applied in the form of a 0.5% topical cream, effects which were suggested to be due to improved hydration of the skin.  Pregnenolone acetate has been marketed in France in a topical cream containing 1% pregnenolone acetate and 10% "sex hormone" for the treatment of premature skin aging but was withdrawn from the market in 1992.  Although the drug has been described by some sources as a glucocorticoid, other authors have stated that systemic pregnenolone acetate has no undesirable metabolic or toxic effects even at high dosages.

Deslorelin: Deslorelin acetate is an injectable gonadotropin releasing hormone super-agonist (GnRH agonist) also known as an LHRH agonist.  Via its indirect action, following an initial surge the production of sex hormones (Androgen and Estrogen) tapers off.
