Comparison of the Administration of 150 or 75 of Recombinant LH in Agonist ICSI Cycles Stimulated with Recombinant FSH in Women Aged 35-39: A Comparative Study.

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.

Effect of vitamin E administered to men in infertile couples on sperm and assisted reproduction outcomes: a double-blind randomized study.

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.

Glutathione peroxidase activity in seminal plasma and its relationship to classical sperm parameters and in vitro fertilization-intracytoplasmic sperm injection outcome.

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).

Efficacy of the levonorgestrel-releasing intrauterine device in the treatment of recurrent pelvic pain in multitreated endometriosis.

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.

Mid-follicular LH supplementation in women aged 35-39 years undergoing ICSI cycles: a randomized controlled study.

This single-centre, randomized, parallel group, comparative study aimed to identify potential benefits of mid-follicular recombinant human LH (r-HLH) supplementation in women aged 35-39 years undergoing ovarian stimulation for intracytoplasmic sperm injection (ICSI). The main endpoint was the number of metaphase II oocytes retrieved. After pituitary suppression with a gonadotrophin-releasing hormone agonist, ovarian stimulation was initiated with recombinant human FSH (r-HFSH; 300-450 IU/day).
