Background: The purpose of the study was to assess whether the coadministration of 150 of recombinant LH instead of 75 in women aged 35-39 improves the results in agonist ICSI cycles stimulated with 300 of recombinant FSH.
Methods: In this study, two ovarian stimulation protocols coexisted which were identical except in the administered dose of recombinant LH, for which some patients received 150 (n=231) and some received 75 (n=216). Both groups received 300 of recombinant FSH.
Objective: To evaluate the influence on sperm parameters and in vitro fertilization (IVF) outcomes of the administration of 400 mg/day of vitamin E for 3 months to men from infertile couples who are undergoing IVF.
Design: Double-blind, placebo-controlled, randomized study.
Setting: Human reproduction unit of a university hospital.
Objective: To relate the glutathione peroxidase (GPX) activity level in human seminal plasma with standard semen parameters and spermatozoa fertilization potential in terms of fertilization and pregnancy rates in an IVF program.
Design: Prospective study.
Setting: Human Reproduction Unit at Cruces Hospital (Vizcaya, Spain).
Objective: To assess the value of the levonorgestrel-releasing intrauterine device (LNG-IUD) in the treatment of pelvic pain in patients with endometriosis in which previous medical and surgical treatments have failed.
Study Design: This prospective study evaluated pelvic pain by means of both a visual analog grading scale and a verbal descriptive grading scale. Pain was evaluated before insertion of the LNG-IUD and afterwards, at 3-month intervals.
Objective: To compare the pregnancy rates (PRs) in intrauterine insemination (IUI) using recombinant FSH (rec-FSH) or highly purified urinary FSH (HP-FSH).
Design: Systematic review and metaanalysis.
Setting: University hospital.
Background: The objective of this study is to investigate the influence of male age on human fertility, defined as the birth rate for a given population.
Methods: Data from the Spanish National Statistics Institute (INE) for the year 2004 from a total of 454,753 newborn infants and sorted by male and female age groups were evaluated. In order to correct the influence of female age-related fertility, a different analysis was performed considering only women under 30 years of age.
Objective: To ascertain if the daily activity in the in vitro fertilization (IVF) laboratory is related to pregnancy rates (PR) and fertilization rates (FR) in an IVF program.
Study Design: A retrospective study was performed to compare the PR and the FR obtained in 845 oocyte retrievals (OR) and 713 embryo transfers (ET), according to the daily workload. Different cutoffs were established: < or = 3 OR per day vs.
Background Information: The execution phase of apoptosis is characterized by extensive blebbing of the plasma membrane, which usually results in secondary lysis in vitro. To analyse the permeability of cellular membranes during this process, we induced apoptosis in human melanoma A375 cells that had been transfected with fluorescently tagged proteins which were targeted to different subcellular locations.
Results: The dual treatment of resveratrol and butyrate produced a synergistic induction of apoptosis by blocking different phases of the cell cycle.
Background: The aim was to ascertain whether using ultrasound guidance during intrauterine insemination (IUI) could increase pregnancy rates (PRs).
Methods: The population under study consisted of 73 consecutive couples subjected to IUI in our Human Reproduction Unit, between June and December 2006, with a total of 231 IUI cycles performed. The patients were randomized using a computer-generated random numeric table into two groups: ultrasound-guided IUI group (n = 33) and clinical IUI group (n = 40).
