Diabetes decreases the fertility of females, but the mechanisms are not completely understood. In our investigations, we have found that 13% of the female BB Wistar rats that spontaneously developed chemical diabetes had persistent estrous. In this study the ovaries of these rats were examined by scanning electron microscopy(SEM) and compared to normal-cycling controls as well as to rats that had developed polycystic ovaries(PCO) by exposure to constant 1ight.

Background: Polycystic ovarian syndrome (PCOS) is a condition characterized by menstrual abnormalities (oligo/amenorrhea) and clinical or biochemical features of hyperandrogenism and may manifest at any age. It is a common cause of female subfertility. All the dimensions of PCOS have not been yet completely explored. Methods: It was a cross sectional comparative study carried out at-GOPD of Shaheed Suhrawardy Medical College & Hospital from January, 2016 to December 2016 on 162 subfertile women. Among them 54 were PCOS group and 108 were non PCOS group. PCOS was diagnosed by (Rotterdam criteria 2003) (i) Oligo or anovulation (ii) hyperandrogenism (iii) Polycystic ovaries. Study was done to evaluate and compare the demographic characteristics, clinical, biochemical and ultrasoundgraphic features of sub-fertile women with and without PCOS. Results: A total of 162 sub-fertile women aged 16-36 years. Mean age was 29.5±5.4. There were significant differences between the two groups in terms of (oligo/amenorrhea), hirsutism, WHR and ovarian ultrasound features. There were no significant differences between two groups in correlations between the level of obesity with the incidence of anovulation, hyperandrogenism or with hormonal features. Conclusion: PCOS is one of the important factors causing Infertility. It is an ill-defined symptom complex needed due attention. There is a need to increase awareness regarding. The clinical features of PCOS are heterogenous thus can be investigated accordingly of selection of appropriate treatment modality. J Shaheed Suhrawardy Med Coll, June 2019, Vol.11(1); 17-23

Hyperprolactinemia is a common endocrine disorder of hypothalamic-pituitary axis. It affect about 4-17% of women in reproductive age and about 3-10% of patients with polycystic ovaries. Vitamin B6 is an effective prolactin inhibitor that is extremely cheap and safe.it exerts hypothalamic dopaminergic effect which causes a significant reduction in prolactin level. The aim of the study is To evaluate the effectiveness of vitamin B6 in reducing serum prolactin in Hyperprolactinemic patient. Compare this effect to that of cabergoline.
