TL;DR: The effects of short-term administration of levonorgestrel (LNG) at different stages of the ovarian cycle on the pituitary-ovarian axis, corpus luteum function, and endometrium were investigated as mentioned in this paper.
Original research article On the mechanisms of action of short-term levonorgestrel administration in emergency contraception
TL;DR: It is suggested that interference of LNG with the mechanisms initiating the LH preovulatory surge depends on the stage of follicle development, and anovulation results from disrupting the normal development and/or the hormonal activity of the growing follicle only when LNG is givenPreovulatory.

Metabolism of levonorgestrel, norethindrone, and structurally related contraceptive steroids
Frank Z. Stanczyk,Subir Roy +1 more
TL;DR: There is limited information on the metabolism of levonorgestrel, norethindrone and structurally related contraceptive steroids, and it appears that neither desogestrel nor gestodene are transformed to the parent compound.

Sex hormone binding globulin capacity as an index of oestrogenicity or androgenicity in women on oral contraceptive steroids
TL;DR: Women with a high pre‐treatment SHBG level might be more suited to combination OC with d‐norgestrel or the 19‐norprogestagen‘mini’pills, while combined OC preparations causing some elevation of SHBG might be preferable.

The influence of hormonal contraceptives on sex hormone binding globulin (SHBG) capacity.
TL;DR: It appeared that the SHBG response to OCs is different from that of transcortin-binding capacity, and the combination of ethinyl estradiol with megestrol acetate gave results comparable with those attained during pregnancy.
