Relationships between total length (TL) and fecundity, body weight and fecundity, ovary length and fecundity, and ovary weight and fecundity of hilsa shad, Tenualosa ilisha Hamilton, collected from Kuakata, Patuakhali, Bangladesh, were studied. During the sampling period, the fecundity of hilsa was found to range from 169,000 (fish TL=28.0cm, weight=250g) to 1,088,000 (fish TL=40.5cm, weight=955g) with a mean of $520{\pm}53{\times}1,000$. The number of eggs per gram of ovary for samples collected from the anterior, middle, and posterior regions of the ovary were also recorded, but no significant variation was found among ovary regions at the 5% level of significance. Fecundity increased with fish TL and weight. The regression equations obtained in arithmetic forms of relationships between TL and fecundity (F), body weight (BW) and fecundity, ovary length (OL) and fecundity, and ovary weight (OW) and fecundity were $F=-887,896+40,511{\times}TL(r=0.85)$, $F=67,577+755.44{\times}BW(r=0.85)$, $F=-562,070+87,668{\times}OL(r=0.75)$ and $F=124,815+6,596.7{\times}OW (r=0.84)$, respectively. The relationships between fecundity and TL, body weight, ovary length, and ovary weight were linear, and the 'r' values were highly significant (p<0.01). These results provide valuable data for the restoration of hilsa resources, which are economically important but have shown reduced productivity in nations adjacent to the Bay of Bengal.

Objectives: The objective of this study is to evaluate weight change and analyze adverse events in overweight and obese women with polycystic ovary syndrome (PCOS) who were prescribed with Gamitaeeumjowee-tang. Methods: A retrospective chart review was conducted for medical records of patients with PCOS, who were administered with Gamitaeeumjowee-tang for a period of 12 weeks between January 2019 and December 2021. Outcomes were total weight loss/weight loss rate, the percentage of patients who lost more than 5% and 10% of their baseline weight. Adverse events (AEs) reported by patients were evaluated by severity, causality and system-organ classes. Results: A total of sixty-seven patients were included (mean±standard deviation, Age 28.78±5.25 years, weight 76.78±12.84 kg, body mass index 29.2±4.26 kg/m²). The average total weight loss in PCOS patients was 6.57±3.07 kg and the average weight loss rate was 8.55±3.65%. The percentage of patients with more than 5% and 10% weight loss compared to their baseline weight was 86.56% and 25.37% respectively. The analysis of adverse events are as follows: Causality assessment with World Health Organization-Uppsala Monitoring Centre of AEs showed 'Unlikely' was the most common (71.7%) and severity evaluations with Common Terminology Criteria for Adverse Events showed almost all symptoms were mild (98.9%). Conclusions: Gamitaeeumjowee-tang helps to lose weight of PCOS patients, which is overweight or obese, and no serious adverse events have occurred. Additional well-designed clinical studies are recommended.

Objectives: This study is to review the effect of Korean medicinal herbs on treatment of polycystic ovary induced rat models reported in domestic & foreign journals. Methods: 7 electronic databases (Pubmed, CNKI, EMBASE, Oasis, RISS, CENTRAL, Koreankt) were searched with term as polycystic ovary, and study reports on polycystic ovary impairment with Korean medicinal herbs. After selecting several studies, the analysis was focused on items reflected in the Rotterdam criteria for diagnosis of polycystic ovary syndrome such as hyperandrogenism (HA), ovarian weight, the number of follicle cysts, estrous cycles, and etc. Results: 15 studies were reviewed. As a polycystic ovary induction material, estradiol valerate (EV) was used in 9 studies, testosterone propionate (TP) in 2 studies and dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), Poretsky's method and letrozole (LE) was used in rest 4 studies, respectively. Tribulus terrestris (TT), Nardostachys jatamansi (NJ), Lycii cortex (LC), Cinnamomum cassia kees (CCK) and Atractylodis macrocephalae koidz (AMK) produced statistically significant results related to hyperandrogenism. In ovarian weight, Silybum marianum (SM), AMK and Alllium sativum (AS) were statistically significant. In the the number of follicle cysts, SM and TT were statistically significant. In estrous cycles, AMK, NJ, TT and Coix lacryma-jobi (CL) were statistically significant. Conclusions: Based on the diagnosis criteria of Rotterdam, TT, NJ, AMK, SM, AS, and CL produced statistically significant results in rat model.

A total of 69 ovaries were collected from 345 camels slaughtered in Maiduguri abattoir, North-Eastern part of Nigeria, to study the influence of season on ovary weight and corpus luteum count in the dromedary (single humped) camel (Camelus dromedaries). Right ovary was significantly heavier (p<0.01) and had more follicular fluid than the left. Although corpus luteum count increased gradually throughout the study period, no camel had 3 active corpora lutea and only 53 out of the total number had two. Ovarian activity seem to be higher in the cold dry harmattan season, November/December, than during the warmer post rainy season, September/October. These periods can be exploited by farmers, especially peasants who rely heavily on natural mating, to obtain greater conception rates and reduce the chance of failure during mating.

Objective: Tributyltin (TBT), an endocrine disrupting chemical, has been reported to decrease ovarian function by causing apoptosis in the ovary, but the mechanism is not fully understood. Therefore, we examined whether TBT increases the expression of adipogenesis-related genes in the ovary and the increased expression of these genes is associated with apoptosis induction. Methods: Three-week-old Sprague-Dawley rats were orally administered TBT (1 or 10 mg/kg body weight) or sesame oil as a control for 7 days. The ovaries were obtained and weighed on day 8, and then they were fixed for terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) or frozen for RNA extraction. Using the total RNA of the ovaries, adipogenesis- and apoptosis-related genes were analyzed by real-time polymerase chain reaction (PCR). Results: The ovarian weight was significantly decreased in rats administered 10 mg/kg TBT compared to that in control rats. As determined by the TUNEL assay, the number of apoptotic follicles in ovary was significantly increased in rats administered 10 mg/kg TBT. The real-time PCR results showed that the expression of adipogenesis-related genes such as $PPAR{\gamma}$, ${\alpha}P2$, CD36, and PEPCK was increased after TBT administration. In addition, apoptosis-related genes such as $TNF{\alpha}$ and TNFR1 were expressed more in the TBT-administered rats compared with the control rats. Conclusion: The present study demonstrates that TBT induces the expression of adipogenesis- and apoptosis-related genes in the ovary leading to apoptosis in the ovarian follicles. These results suggest that the increased expression of adipogenesis-related genes in the ovary by TBT exposure might induce apoptosis resulting in a loss of ovarian function.

Petroleum ether, benzene and alcohol extracts of seeds of C. juncea administered orally at the dose level of 25mg/100g body weight to adult female mice for 30 days, resulted in irregular estrous cycle with prolonged estrus and metaestrus and reduced diestrus and proestrus during the experimental period. Histological studies of the ovary indicate increases in the number of atretic follicles but decreases in the number of developing follicles, Graafian follicles and corpora lutea. The total cholesterol content of the ovary is increased, whereas ascorbic acid content is decreased. The weight of the uterus and its micrometric measurement in all experimental mice are increased significantly. The alcoholic extracts showed estrogenic activity in immature mice by early opening of the vagina, premature cornification of the vaginal epithilium and increases in uterine weight. However, alcohol extract of seeds of C. juncea was more effective in causing these changes compared to other extracts. After subjecting to preliminary phytochemical screenings alcohol extract showed positive; test for alkaloids, steroids, glycosides, flavones, phenols and tannins.
