An infertile couple was referred for intracytoplasmic sperm injection (ICSI) because of primary infertility and oligoasthenoteratozoospermia (OAT) in the male. It was observed that although the sperm cells presented with an unusual head size and multiple tails they were able to fertilize the oocytes after ICSI. Subsequent molecular cytogenetic analysis(More)
BACKGROUND The measurement of circulating anti-Müllerian hormone (AMH) has been applied to a wide array of clinical applications, mainly based on its ability to reflect the number of antral and pre-antral follicles present in the ovaries. AMH has been suggested to predict the ovarian response to hyperstimulation of the ovaries for IVF and the timing of(More)
The clinical use of anti-Müllerian hormone (AMH) has increased exponentially due to its unique relationship with the ovarian reserve and ability to predict ovarian response, facilitate pretreatment counselling and individualize treatment strategies to minimize the risk of ovarian hyperstimulation syndrome. There is now a rapidly increasing literature(More)
OBJECTIVE To determine the frequency of clinical discordance between antimüllerian hormone (AMH, ng/mL) and follicle-stimulating hormone (FSH, IU/L) by use of cut points defined by response to controlled ovarian stimulation in the same serum samples drawn on estradiol-confirmed, menstrual cycle days 2 to 4. DESIGN Retrospective analysis. SETTING(More)
Knowledge about the status of the female reproductive system is important for fertility problems and age-related family planning. The volume of these fertility requests in our emancipated society is steadily increasing. Intravaginal 3D ultrasound imaging of the follicles in the ovary gives important information about the ovarian aging, i.e. number of(More)
The ability to predict the response potential of women to ovarian stimulation may allow the development of individualized ovarian stimulation protocols. This tailored approach to ovarian stimulation could reduce the incidence of ovarian hyperstimulation syndrome in women predicted to have an excessive response to stimulation or could improve pregnancy(More)
Gonadotrophin-releasing hormone (GnRH) agonists are widely used in the treatment of women with symptomatic leiomyomas. The effectiveness of this treatment, as far as symptoms are concerned, is well established, and in recent years many studies have contributed to defining the optimal role for GnRH agonists. Side-effects and health risks prohibit the(More)
In this randomized, controlled, open-label, phase IV study, ovarian response after a follitropin alfa starting dose determined by the CONSORT calculator was compared with a standard dose (150 IU). Normo-ovulatory women (aged 18-34 years) eligible for assisted reproductive techniques were recruited (23 centres: nine European countries and Chile); 200 women(More)
Drugs produced through the use of recombinant DNA techniques have become an integral part of medical practice. Before recombinant FSH (rFSH) was introduced in 1996, FSH purified from the urine of postmenopausal women had been commercially available since the 1960s. We analysed the diffusion and the substitution patterns of the different FSH preparations in(More)
The possibilities and limitations of basal body temperature (BBT) records as an adjunct in the management of infertility were re-evaluated. To assess its accuracy as an index of ovulation, 172 charts were analyzed by three different physicians. While the average true positive rate was 90%, the false negative rate was only 2%. The remaining graphs (8%) were(More)
