This study was conducted to investigate the effect of different doses injection of human chorionic gonadotropin (HCG) hormone on fecundity and serum sex hormones (FSH, LH, estrogen (E2), progesterone (P4), testosterone (T)) of African catfish (Clarias gariepinus). African catfish spawners were intermuscularly injected with different doses of HCG (500, 1500, 3000, 6000 IU/kg female), and group is not injected as a control; males were injected at half the female dose. The results showed that, fish group injected by 6000 IU HCG/ kg female had the highest gonadsomatic index, absolute fecundity and relative fecundity, while, the lowest value of absolute fecundity and relative fecundity were recorded with 500 IU HCG/ kg female. The group injected with the highest amount of HCG (6000 IU/ kg female) recorded the lowest value from egg diameter, while the highest egg diameter was observed in 500 IU HCG/ kg female. In females, the group injected with 6000 IU HCG/ kg female reflected the lowest level of FSH and the highest level of LH and the highest level of P4 compared to other treatments. Level of T recorded the highest level with 1500 IU HCG/ kg female. The control group reflected the highest level of FSH and E2, while the control group reflected the lowest level of T and P4 level. In males, serum FSH, LH, P4 and E2 in male groups injected with HCG were relatively higher than those recorded in the control group. The highest level of T was recorded in treatment injected with the highest dose of HCG and decreased in other treatments until recorded the lowest level of T in the control group. It was observed, HCG hormone has successfully and accelerate induced spawning in African catfish (Clarias gariepinus) and increased in reproductive performance with the increase in HCG dosage and as compared to group not injected.

The present study was conducted to examine the effects of three different hormonal treatment types i.e., pituitary extract (Pt), ovaprim (Ov) and human chorionic gonadotropin (HCG) + Metoclopramide (Met) on reproductive performance of Caspian shemaya, Alburnus chalcoides (Guldenstadt, 1772). To this end, three experimental treatments and one control group were considered. The experimental groups were administrated with different doses of Pt, Ov, HCG + Met as follows: Pt [2 mg kg bw (body weight)-1], Pt (3 mg kg bw -1), Pt (4 mg kg bw -1), Ov (10 μg kg bw -1), Ov (20 μg kg bw -1), Ov (30 μg kg bw -1), HCG + Met (1000 IU kg bw -1), HCG + Met (2000 IU kg bw -1), HCG + Met (3000 IU kg bw-1) and also a control group without any hormonal treatment. The highest values of oocyte weight and egg diameter were observed in groups administrated with Ov (10 μg kg bw-1) and HCG + Met (2000 IU kg bw-1) respectively. The highest values of absolute fecundity and relative fecundity were recorded for fish administrated with Ov (20 μg kg bw-1). The latency period and hour-degree for final maturation were lower in fish administrated with Ov (10 μg kg bw-1) compared to other experimental groups (p<0.05). There were no significant differences between experimental groups in terms of other assayed parameters. The results of the present study demonstrated higher efficiency of ovaprim in improving the reproductive performance of Caspian shemaya.

Background. Although the association between human chorionic gonadotropin (hCG) and hyperandrogenism was identified more than 40 years ago, relevant questions remain unanswered.Design and Methods. We conducted a prospective, longitudinal, and controlled study in 23 women with a diagnosis of a complete hydatidiform mole (HM).Results. All participants completed the study. Before HM evacuation mean hCG was markedly higher in the cases than in the control group (P≤0.001). Free testosterone (T) and dehydroepiandrosterone sulfate (DHEA-S) were found to be higher in the cases (2.78 ± 1.24 pg/mL and 231.50 ± 127.20 μ/dL) when compared to the control group (1.50 ± 0.75 pg/mL and 133.59 ± 60.69 μ/dL) (P=0.0001and 0.001), respectively. There was a strong correlation between hCG and free T/total T/DHEA-S concentrations (r=0.78;P≤0.001,r=0.74;  P≤0.001, andr=0.71;  P≤0.001), respectively. In the cases group 48 hours after HM evacuation, hCG levels were found to be significantly lower when compared to initial levels (P=0.001) and free T and DHEA-S declined significantly (P=0.0002and 0.009).Conclusion. Before uterus evacuation, hCG, free T, and DHEA-S levels were significantly higher when compared with controls finding a strong correlation between hCG and free T/DHEA-S levels. Forty-eight hours after HM treatment hCG levels declined and the difference was lost. A novel finding of our study is that in cases, besides free T, DHEA-S was also found to be significantly higher and both the ovaries and adrenal glands appear to be the sites of this androgen overproduction.

Background: Several mediators play an important role in implantation. One of these mediators is human chorionic gonadotropin (HCG). Objective: To evaluate the effects of HCG intrauterine injection on the day of oocyte retrieval on the result of assisted reproductive techniques (ART). Materials and Methods: In this randomized clinical trial study, 126 women who were referred to Afzalipour Infertility Center between December 2018 to December 2019 undergoing in vitro fertilization/intracytoplasmic sperm injection cycles were enrolled and assigned to two groups of: a case (n = 62) and a control group (n = 64). The protocols for both groups were the same; except that the case group was injected with the protocols for both groups were the same, except that the case group was injected with 1000 IU of HCG into uterine cavity following the oocyte puncture, while no medication was administered to the control group. The implantation rate, chemical pregnancy, clinical pregnancy, and abortion rates were compared between the two groups. Results: Positive chemical pregnancy was seen in 15 (27.3%) cases of the case group and 14 (25.5%) of the control group. No significant difference was seen in the chemical and clinical pregnancy rates between the groups. The abortion rate was higher in the control group but that was not significant. Conclusion: A 1000 IU of HCG intrauterine injection after oocyte retrieval does not improve implantation, chemical or clinical pregnancy rates in ART cycles. Further studies are needed to clearly understand the role of HCG intrauterine injection in the day of oocyte retrieval in ART outcomes. Key words: Oocyte retrieval, Chorionic gonadotropin, Pregnancy, Assisted reproductive techniques.
