- To produce luteinization of a persistent follicular cyst: If effective, will convert from proestrus to estrus in 1-2 days and sexual behavior should stop within 2 weeks.
- Infertile bitches cycling normally with low progesterone due to lack of corpus luteum formation: Give on days 10-11 of heat cycle or when vaginal smear indicates breeding readiness. Breed 2 days after administration.
- Male infertility secondary to low testosterone, LH and FSH: Add PMSG 20 Units/kg SC 3 times weekly. Continue for 3 months. Once spermatogenesis ensues, may continue with HCG only.

- Treatment of persistent follicles during the early transition period: Results are variable.
- To hasten ovulation and reduce variability of estrus after prostaglandin synchronization: Give 5-6 days after the second prostaglandin treatment or on the first or second day of estrus.

개요
HCG는 임산부의 소변에서 추출한 폴리펩타이드 호르몬으로, 주로 황체 형성 호르몬(LH)의 작용을 모방하며 일부 난포 자극 호르몬(FSH) 활성을 가집니다. 수의학에서는 소의 낭종성 난소, 잠복고환증 치료 및 생식샘 기능을 평가하기 위한 HCG 자극 검사 등 다양한 동물의 번식 장애에 널리 사용됩니다.
작용 기전
HCG is a glycoprotein that primarily mimics the action of luteinizing hormone (LH), with minor follicle-stimulating hormone (FSH)-like activity.
- In Males: Binds to LH receptors on testicular interstitial (Leydig) cells → stimulates differentiation and androgen (testosterone) production → promotes testicular descent and spermatogenesis.
- In Females: Binds to LH receptors on the ovary → stimulates the corpus luteum to produce progesterone → triggers ovulation of mature follicles. In bitches, it also induces estrogen secretion.
안전성·주의사항
금기사항
- Androgen-dependent neoplasias (e.g., prostatic carcinoma)
- Precocious puberty
- Known hypersensitivity to HCG
- Pregnancy (FDA Category X in humans, unless specifically indicated for reproductive management)
부작용
- Hypersensitivity reactions / Anaphylaxis
- Pain at the injection site
- Antibody production leading to diminished efficacy (with repeated use)
- Abortion in mares if given prior to the 35th day of pregnancy
- Gynecomastia, headache, depression, irritability, and edema (reported in humans)
주의
Warning: Antibody production to this hormone has been reported after repetitive use, resulting in diminished effect.
- Pregnancy: FDA Category X in humans (risk of use clearly outweighs any possible benefit). May cause abortion in mares prior to the 35th day of pregnancy due to increased estrogen levels.
- Administration: Must be given parenterally; it is destroyed in the GI tract if given orally.
모니터링
- Testosterone levels (for HCG challenge test in males)
- Progesterone levels (for HCG challenge test in females)
- Resolution of clinical signs (e.g., cessation of estrus behavior, resolution of cystic ovaries)
- Signs of hypersensitivity or anaphylaxis post-injection
약동학
흡수
Destroyed in the GI tract after oral administration; must be given parenterally. After IM injection, peak plasma levels occur in about 6 hours.
분포
Distributed primarily to the ovaries in females and to the testes in males. Some may also be distributed to the proximal tubules in the renal cortex.
배설
Eliminated from the blood in a biphasic manner. The initial elimination half-life is about 11 hours and the terminal half-life is approximately 23 hours.
과다투여
No overdosage cases have been reported with HCG in veterinary medicine.

보호자 정보
이 약물은 주사로만 투여해야 합니다. 주사 부위에 통증이 발생할 수 있습니다. 반려동물에게 알레르기 반응(호흡 곤란, 안면 부종 등)이 나타나는지 주의 깊게 관찰하십시오. 반복적으로 사용하면 항체가 형성되어 효과가 감소할 수 있습니다.
