Postovulatory treatment with GnRH on day 5 reduces pregnancy loss in recipients receiving an in vitro produced expanded blastocyst.
Effect of treatment with human chorionic gonadotropin 7 days after artificial insemination or at the time of embryo transfer on reproductive outcomes in nulliparous Holstein heifers.
TLDR
It is concluded that treatment with 2,000 IU of hCG 7 d after AI or at the time of embryo transfer increased P4 concentrations without affecting P/AI or P/ET in nulliparous Holstein heifers.
Effects of supplemental progesterone using a CIDR insert on pregnancy per embryo transfer of dairy heifer recipients of embryos produced in vitro.
Evaluation of treatments with hCG and carprofen at embryo transfer in a demi-embryo and recipient virgin heifer model.
TLDR
Low developmental competence embryos showed an intrinsic deficiency in overcoming the maternal recognition of pregnancy challenge and in proceeding to further development until Day 28 of pregnancy, whereas mortality beyond this point was residual.
Secondary corpora lutea induced by HCG treatment enhanced demi-embryo survival in lactating high-yielding dairy cows.
TLDR
Primary CL induced by hCG treatment at ET significantly increased plasma P4 concentrations, the survival rate of demi-embryos and the pregnancy rate of high-yielding lactating dairy cows.
Administration of human chorionic gonadotropin to improve luteal function in lactating beef cattle.
TLDR
Evaluated the effects of administration of hCG on day 4 after FTAI on induction of ovulation of the first dominant follicle, corpus luteum (CL) development, progesterone production and pregnancy rate in lactating beef cows found it to be an alternative that can improve fertility, enhancing embryonic development and reducing early pregnancy loss.
Effects of hCG administration on corpus luteum development and plasma sex steroid hormone concentration in beef heifers differ according to the locational relationships of the original corpus luteum and the first-wave dominant follicle
TLDR
It is indicated that the hCG treatment more significantly promoted CL development and increased plasma P4 concentration in the contralateral than in the ipsilateral group.
The Effect of Intrauterine Administration of Human Chorionic Gonadotropin (hCG) Before Embryo Transfer During Assisted Reproductive Cycles: a Meta-Analysis of Randomized Controlled Trials
TLDR
The current evidence indicates that intrauterine hCG administration before ET provides an advantage in terms of the clinical pregnancy and ongoing pregnancy rates.
Effect of hCG administration on Day 7 post-mating on accessory corpus luteum development and progesterone concentration in llamas.
The efficacy of intrauterine injection of human chorionic gonadotropin before embryo transfer in assisted reproductive cycles: Meta-analysis
TLDR
Intrauterine hCG injection significantly increased rates of biochemical, clinical and ongoing pregnancy compared with controls and women undergoing IVF/ICSI may benefit from intrauterinehCG injection before embryo transfer.

Improvement of pregnancy rate in Japanese Black cows by administration of hCG to recipients of transferred frozen-thawed embryos.
Evaluation of human chorionic gonadotropin as a replacement for gonadotropin-releasing hormone in ovulation-synchronization protocols before fixed timed artificial insemination in beef cattle.
TLDR
Compared with a breeding season having only 1 TAI and longer exposure to cleanup bulls, total breeding season pregnancy rate was reduced by one-third, subsequent calving distribution was altered, and 50% more AI-sired calves were obtained by applying 2 TAI during the breeding season.
Effect of human chorionic gonadotrophin on dominant follicles in cows: formation of accessory corpora lutea, progesterone production and pregnancy rates.
TLDR
It is suggested that hCG treatment at 7 days after insemination could be used to produce accessory corpora lutea, raise plasma progesterone concentration and hence reduce the incidence of early embryonic mortality in cattle.
Effects of Human Chorionic Gonadotrophin Administration on Artificial Insemination Pregnancy Rates in Beef Heifers
TLDR
Whether administering human chorionic gonadotropin at 5 d post-AI improves fertility in beef heifers by increasing serum progesterone concentrations by P>0.10 is investigated.
Effect of human chorionic gonadotropin administered at specific times following breeding on milk progesterone and pregnancy in cows.
Ovulation and pregnancy outcomes in response to human chorionic gonadotropin before resynchronized ovulation in dairy cattle.
Effect of human chorionic gonadotropin on luteal function and reproductive performance of high-producing lactating Holstein dairy cows.
TLDR
Treatment with hCG on d 5 after AI induces accessory CL, enhances plasma progesterone concentration, and improves conception rate of high-producing dairy cows, and pregnancy losses were similar between treatment groups.
Effects of hormonal treatments on reproductive performance and embryo production.
Effect of administration of human chorionic gonadotropin after artificial insemination on concentrations of progesterone and conception rates in beef heifers.
TLDR
Administration of hCG 5 to 6 d after AI did not improve conception or pregnancy rates at two out of three locations evaluated, suggesting insufficient progesterone is not a major factor contributing to early pregnancy failure in beef heifers.
Ability of induced corpora lutea to maintain pregnancy from the third month of gestation to term in cattle.
