“…Przy użyciu progestagenów leczono też skutecznie suki, u których okresy pomiędzy rujami były skrócone poniżej 4 miesięcy, co jest związane z niepłodnością. Stosowano mianowicie doustnie octan megestrolu w dawce 2 mg/kg oraz octan chlormadinonu w dawce 0,5 mg/kg, co skutkowało przesunięciem rui i uzyskaniem ciąży (49). Wydaje się, że te preparaty mogłoby być wykorzystane także do wydłużenia ciąży.…”

“…Furthermore, if infertility resulted from short estrous period, bitches are reported to return to normal fertility in the following cycles when estrus is suppressed with synthetic progestin administration. For this purpose, 2 mg/kg per day megestrol acetate or 0.5 mg/kg per day of chlormadinone acetate may be administered for 8 days, so administration should begin within a maximum of 3 days following the beginning of proestrus [29].…”

“…Tais drogas são normalmente utilizados como medicamentos contraceptivos devido ao seu efeito de retroalimentação negativa sobre o hipotálamo e hipófise, inibindo a liberação de GnRH (Wanke et al, 2006), suprimindo o desenvolvimento foilcular, bem como a liberação de LH e FSH (Root Kustritz, 2012). Os tipos de progestágenos mais comumente utilizados são os sintéticos como acetato de megestrol, acetato de medroxiprogesterona e proligestona (Root Kustritz, 2012).…”

No anestro ocorre a regeneração uterina e preparação endócrina para o ciclo subsequente e caso o mesmo seja reduzido, levando a um intervalo interestral inferior a quatro meses, podendo resultar em causas de infertilidade.…”
