The moral object determines whether or not an act is intrinsically evil. The moral object is the end in terms of morality toward which the act is inherently directed. It is not the intended end or the purpose for which the act was chosen.
I did not say that hormonal treatments (by which you mean the same hormones used in abortifacient contraceptives) are intrinsically evil. An act is intrinsically evil if it has an evil moral object. The description of ‘hormonal treatments’ does not contain enough information to determine the moral object. A woman who is not sexually active, or who is infertile due to old age, injury, previous hysterectomy (to treat a medical disorder) can use an abortifacient contraceptive only if and when this medication would not be abortive or contraceptive.
Some ‘hormonal treatments’ are intrinsically evil, because they deprive the sexual act of the procreative meaning and/or deprive the prenatal of life. Other hormonal treatments are moral.
The principle of double effect never justifies an intrinsically evil act:

You will not find a magisterial document giving blanket approval or condemnation for ‘hormonal treatments’ because the moral object is not clear from that general term. There are documents that condemn all contraception in any form, and all direct abortion in any form, whether as an end or as a means.
The intention to contracept, i.e. deliberate contraception, is in the first font of morality (the intended end or purpose for which the act was chosen). Whether or not a deliberately chosen (intentionally chosen) act is contraception or abortion depends on the moral object, not the intention. Choosing direct abortion with the intention of saving the life of the mother is still intrinsically evil, even though the prenatal’s death is not deliberately intended, because the deliberately chosen act is inherently ordered toward the death of the prenatal.
Whether or not the abortion or the contraception is intended or desired does not determine if it is an effect in the third font (consequences) or the moral object. Certain kinds of acts are intrinsically disordered regardless of the intentions or desires of the person deliberately choosing that act.
When a ‘hormonal treatment’ deprives the sexual act of its procreative meaning OR deprives an innocent prenatal of life, then that treatment is abortive or contraceptive. When such a treatment does not abortive or contraceptive, then it may be moral.
Whenever a magisterial document uses a term such as deliberate or intentional, we must distinguish which font is being referred to. The deliberate intention can never make an intrinsically evil act moral. For example, direct abortion to save the life of the mother is never moral. The intention is to save the life of the mother, but the deliberately chosen act itself (the intentionally chosen act) is inherently directed at the deprivation of life of the prenatal.
Veritatis Splendor makes it very clear that the intention or purpose for which the act is chosen cannot change the moral object.
Pope John Paul II: “Consequently, circumstances or intentions can never transform an act, intrinsically evil by virtue of its object, into an act ‘subjectively’ good or defensible as a choice.” (Veritatis Splendor, n. 81.)
Pope John Paul II: “No circumstance, no purpose, no law whatsoever can ever make licit an act which is intrinsically illicit, since it is contrary to the Law of God which is written in every human heart, knowable by reason itself, and proclaimed by the Church.” (Evangelium Vitae, n. 62.)
The Catechism of the Catholic Church: “It is therefore an error to judge the morality of human acts by considering only the intention that inspires them or the circumstances (environment, social pressure, duress or emergency, etc.) which supply their context. There are acts which, in and of themselves, independently of circumstances and intentions, are always gravely illicit by reason of their object; such as blasphemy and perjury, murder and adultery. One may not do evil so that good may result from it.” (CCC, n. 1756.)
