Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age characterized by chronic anovulation and polycystic ovary morphology and/or hyperandrogenism. Management of clinical manifestations of PCOS, such as menstrual irregularities and hyperandrogenism symptoms, includes lifestyle changes and combined hormonal contraceptives (CHCs). CHCs contain estrogen that exe...
In the time of transition from premenopausal state to postmenopausal state the capacity of ovary producing sex hormones including estrogens, progesterone and testosterone cuts down [1]. Due to the menopause the level of serum oestrogen dramatically decreases, which increases the production of bone-resorbing cytokines and osteoblasts and then increases the number and activity of osteoclast, ther...
The present review summarises knowledge of the reproductive response of anoestrous ewes to the introduction of rams - in other words, the ram effect. The ovarian and endocrine response, the factors that determine whether ewes will respond or not (associated with both the stimulus and the receptivity of the ewes) and some aspects of practical management are discussed. Information on the use of t...
Estradiol (E2), estrone (El ) , progesterone, LH and prolactin concentrations were determined by radioimmunoassay in blood plasma samples from parous ewes treated with medroxyprogesterone acetate (MAP) or melengestrol acetate (MGA) orally, with MAP by intravaginal sponge, or progesterone by intramuscular injection. Treatment was begun on Day 10 of the estrous cycle and continued for 14 days. Bl...
Recent research has not been able to demonstrate close endometrial morphological correlations with specific abnormalities of menstrual bleeding, but has pointed to an increasing number of molecular mechanisms that may be involved in the occurrence of certain forms of abnormal uterine bleeding. Ovulatory and anovulatory dysfunctional uterine bleeding (DUB) and progestogen-related breakthrough bl...
In a survey of 461 women routinely attending family planning clinics, those taking oral contraceptives had significantly higher mean systolic and diastolic blood pressures than those using non-hormonal contraception. There appeared to be a dose-response relation of blood pressure to the progestogen component of 2 oral contraceptives with an identical 30 micrograms ethinylestradiol component. ...
With the purpose of measuring the duration of the functional life-span (FLS) of the anovulatory follicle in women under continuous low-dose progestogen treatment, the oestradiol curve of Norplant implant users was retrospectively analysed. From all the data collected during the previous 5 years at the Department of Biomedical Research at the Family Planning Clinic of Profamilia, Santo Domingo, ...
BACKGROUND Preterm birth is the principal factor contributing to adverse outcomes in multiple pregnancies. Randomized controlled trials of progestogens to prevent preterm birth in twin pregnancies have shown no clear benefits. However, individual studies have not had sufficient power to evaluate potential benefits in women at particular high risk of early delivery (for example, women with a pre...
CONTEXT Several areas exist in the practice of contraception where evidence for practice is deficient, yet clinical decisions need to be made. OBJECTIVES The aim of the study was to find the practice habits of lead practitioners in the area of contraception in specific clinical scenarios where the published evidence is inadequate to provide clear guidance to clinicians. Results can provide 'L...
