OBJECTIVE To evaluate and compare IVF outcomes of patients within different age categories who had a normal basal FSH level with outcomes of patients with an elevated day 3 FSH level. DESIGN Retrospective analysis. SETTING Large, private IVF center. PATIENT(S) We analyzed 2,708 patients. Of these, 2,477 had normal basal FSH levels, and 231 had elevated basal FSH levels (> or =13.03 IU/L)....

Basal and LH-RH induced plasma FSH and LH levels were determined longitudinally in 41 patients aged 4 to 22 years with Turner's syndrome and in 4 male patients with prepubertal castration. In 12 patients with Turner's syndrome over 18 yrs of age without pubertal change, basal and LH-RH induced FSH levels studied at age 11--22 yrs were all significantly increased over normal levels. However, som...

BACKGROUND Detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of FSH is one of the most important goals in assisted reproductive technique (ART). OBJECTIVE To evaluate whether high level of anti-mullerian hormone level is related to success of ART in patients with temporarily or consistently elevated early f...

Kallmann's syndrome is a neuronal migration disorder characterised by anosmia/hyposmia and hypogonadotropic hypogonadism. We present a case of a 21-year-old man who was unable to sense smell since birth and who displayed non-development of secondary sexual characteristics for the past 10 years. Blood investigations showed low basal levels of serum follicle stimulating hormone (FSH), serum lutei...

BACKGROUND During the course of assisted reproduction treatment, a number of women exhibit a "poor response" to ovulation induction, or demonstrate an elevated basal FSH level (> or =10 IU/l) at a young age. We sought to determine whether these women are at increased risk of early menopause and poor reproductive performance. METHODS A retrospective cohort study included 118 "poor responders" ...

CONTEXT Basal FSH is a marker for ovarian reserve. OBJECTIVES The objective of the study was to investigate the predictive value of basal FSH on spontaneous ongoing pregnancy in subfertile ovulatory women. DESIGN This was a prospective cohort study. SETTING The study was conducted in 19 fertility centers in The Netherlands. PARTICIPANTS Subfertile ovulatory women without two-sided tubal...

BACKGROUND To evaluate basal testosterone (T) levels during follicular phase of the menstrual cycle as a predictor for ovarian response and in vitro fertilization (IVF) outcome. METHOD We analyzed data retrospectively from hospital-based IVF center including one thousand two hundred and sixty Chinese Han women under their first IVF cycle reached the ovum pick-up stage, without polycystic ovar...

OBJECTIVE To analyze IVF outcomes in patients with a history of one or more elevations in basal FSH who have a normal basal FSH at the start of their IVF cycle, compared with the general IVF population. DESIGN Retrospective clinical study. SETTING University hospital. PATIENT(S) General IVF patient population. INTERVENTION(S) Patients received standard IVF gonadotropin protocols, oocyte...

An appropriate clinical evaluation and a proper treatment of women are essential for a positive outcome of assisted reproductive technology (ART) cycles. In order to obtain good results it is necessary to assess ovarian reserve before planning treatment. The determination of ovarian reserve by measuring day 3 basal FSH among normal cycling women is one of the most commonly used tests for predic...

background: the ability of the ovary to respond to exogenous gonadotrophin stimulation and development of several follicles is essential in assisted reproductive technology. neither age and regularity of menses nor follicular phase fsh and estradiol concentrations are reliable predictors of ovarian response. day 3 serum inhibin-b level, during induction ovulation, has been proposed as a predict...
