OBJECTIVE: To evaluate the effectiveness of IVF in couples with infertility. DESIGN: Two hundred forty-five consecutive couples with infertility were randomized to receive one cycle of IVF treatment (experimental group) or to wait for a period of 6 months before receiving IVF treatment, during which time other infertility treatments could ...
Moeloek F A - - 1993
It has been reported that there exists a correlation between endometriosis and the luteal phase defect (LPD) as one of the determinants in infertility. In some theories, the hampered maturation of the corpus luteum is believed to be caused by the reduction of LH receptors, increase in prolactin, prostaglandin and ...
Doody M C - - 1993
The life table analysis of infertility study data uses information from patients who drop out and are lost to follow-up. The fact that drop-out patients were not pregnant when last seen has been taken to be useful information that has been entered into the calculation of cumulative pregnancy rates for ...
Harrison R F - - 1993
On the basis of LH and FSH data the incidence of PCOS in a series of 33 infertile women with hyperprolactinemia due to differing causes was found to be 39%. Where the elevations of prolactin were intermittent (spikers), the incidence was 44%, compared to 33% in a control population and ...
Jansen R P - - 1993

RESULTS: One hundred cycles were started; 93 ...
Lobo R A - - 1993
Unexplained infertility is a nebulous diagnosis that is justified only after a thorough and meticulous investigation of both partners. Even if the five basic tests constituting the infertility investigation have not revealed an abnormality, there may be a specific cause. Diagnosing unexplained infertility in this setting is somewhat arbitrary. In ...
Eggert-Kruse W - - 1993

Consideration of symptoms reveals serious shortcomings in pathology-based classifications of endometriosis. Premenstrual spotting may be associated with the underlying physiologic or biochemical disturbance. Once the biochemical basis for spotting can be established, noninvasive tests may be developed for diagnosis and assessment. Endometriosis-related infertility is best assessed by its duration. A ...
Fluker M R - - 1993
This retrospective study evaluated conception rates in 18 women with refractory anovulatory infertility undergoing hMG ovulation induction in the presence of persistent mild to moderate semen abnormalities. Logistic regression analysis showed no relationship between conception (9.6% cycle) and the age of either partner, primary versus secondary infertility, or lowest sperm ...
Peters A J - - 1993

Hull M G - - 1992
The effectiveness of infertility treatments is still questioned, particularly the assisted conception methods because of their complexity and cost. Furthermore, pregnancies often occur independent of treatment but many treatments have not been properly evaluated. The most basic audit of outcome with or without treatment requires pregnancy and preferably birth rates ...
Simpson C W - - 1992
