BACKGROUND: In mare, different methods of earlier cyclicity induction and hastening first ovulation of the year have been reported. OBJECTIVES: The goal of present study was to investigate the effect of progesterone (Cue-mate®) on synchronization and acceleration the first ovulation of the year in winter anestrous mares under artificial lighting system. METHODS: After detection of anestrus mare...

Background: With all the recent advances in cancer treatments, many young cancer patients find themselves facing the prospect of losing their fertility after aggressive chemotherapy or radiotherapy. Cryopreservation of ovarian cortical tissue has emerged as a potential option to restore fertility in these young women. Materials and Methods: Because autotransplantation of cryopreserved ovarian c...

The Pacific white shrimp Litopenaeus vannamei is an economically important penaeid species worldwide. Under farming conditions, the full ovarian maturation of L. generally depends on combination artificial ablation unilateral eyestalk and feeding high-quality natural diets, suggesting that nutrient accumulation to maturation. In this study, we aimed investigate gene expression related nutrition...

A 32-year-old woman (gravida 2, para 1) became pregnant after induced ovulation with human menopausal gonadotrophin and artificial insemination. At 5 weeks' gestation, she reported right lower abdominal pain was diagnosed ovarian hyperstimulation syndrome transferred to this hospital. gestational sac present in the uterus, tumors 11.6 × 5.6 cm on 4.7 4.1 left were noted. The gradually decreased...

Bactrocera minax (Enderlein) (Diptera: Tephritidae) is a major citrus pest in China, whose artificial rearing technology of the adult is not well documented to date. In this study, we tried to determine if supplementing proteins to the adult diet could result in the enhancement of some fitness parameters of B. minax. Four feeds with varying protein source were provided as F0 (water), F1 (sucros...

Populations of Coilia nasus demonstrate asynchronous ovarian development, which severely restricts artificial breeding and large-scale cultivation. In this study, we used a combination of transcriptomic and metabolomic methods to identify the key signaling pathways and genes regulation affecting ovarian development. We identified 565 compounds and generated 47,049 unigenes from ovary tissue. Fi...

BACKGROUND Ovarian tissue cryopreservation followed by transplantation after cancer remission is the most commonly applied fertility restoration approach in very young girls and women who require immediate cancer therapy. However, clinicians strongly advise against reimplantation of one's own ovarian tissue when there is a high risk of recurrence after grafting. For these patients, development ...
