Induction of pre-ovulatory gonadotrophin surge with gonadotrophin-releasing hormone agonist compared to pre-ovulatory injection of human chorionic gonadotrophins for ovulation induction in intrauterine insemination treatment cycles.
The clinical outcome of intrauterine insemination (IUI) treatment cycles employing a gonadotrophin-releasing hormone agonist [GnRHa, triptorelin (Decapeptyl)] or human chorionic gonadotrophin (HCG) for ovulation induction was compared. A group of 48 patients presenting with amenorrhoea, oligomenorrhoea or unexplained infertility were all treated with human menopausal gonadotrophins (HMG) from d...
متن کاملThe effect of equine chorionic gonadotrophin (ecg) injection combined with prostaglandin F2α (pGF2α) and gonadotrophin releasing hormone (GnRH) treatment on reproductive performance of Zandi ewes during non-breeding season
In this study, we aimed to investigate reproductive performance in estrus-induced Zandi ewes treated with equine chorionic gonadotrophin (eCG) injection in combination with prostaglandin F2α (PGF2α)and gonadotrophin releasing hormone (GnRH) during non-breeding season. The estrous cycle was synchronized using controlled internal drug release (CIDR) for 12 days. The ewes were randomly assigned to...
متن کاملVariations in patterns of follicle development in prolific breeds of sheep.
Prolific breeds of sheep (Romanov, Finn and Booroola Romanov crosses heterozygous for the Booroola gene (F+) were compared with breeds of lower prolificacy (Ile-de-France, Finn X Scottish Blackface, Merino X Blackface and Booroola X Romanov not carrying a copy of Booroola gene (++] by in-vivo monitoring of follicular kinetics by ink labelling during the late luteal phase and follicular phase of...
متن کاملHuman chorionic gonadotrophin luteal support overcomes luteal phase inadequacy after gonadotrophin-releasing hormone agonist-induced ovulation in gonadotrophin-stimulated cycles.
Gonadotrophin-releasing hormone agonist (GnRHa)-induced ovulation after gonadotrophin ovarian stimulation is used to prevent ovarian hyperstimulation syndrome and multiple pregnancy in polyfollicular cycles. However, one of the major problems to be resolved is corpus luteum function after follicular maturation and ovulation by mid-cycle GnRHa administration. The present report investigated the ...
متن کاملFertility Rates of Ewes Treated with Medroxyprogesterone and Injected with Equine Chorionic Gonadotropin plus Human Chorionic Gonadotropin in Anoestrous Season
The aim of the present paper was to investigate the efficiency of the equine chorionic gonadotropin (eCG) plus human chorionic gonadotropin (hCG) associated with medroxyprogesterone acetate (MAP) to estrous ewes synchronization. Ninety Texel ewes were investigated during seasonal anoestrous. The ewes received intravaginal sponges containing MAP (60 mg) for nine days. At the time of sponges' wit...
