Active clinical trials for "Infertility, Male"

Worldwide infertility affects about 15 % of reproductive-age couples. In many cases, infertility can't be treated, new treatment options with promising value were involved in the recent clinical trials.

This is a prospective non-randomized unicentric clinical trial, characterized by the inclusion of obese (BMI> 35) male with subfertility (sperm count showing low sperm counts and / or motility and / or morphology and / or DNA fragmentation). Patients selected at the endocrinology obesity HC-FMUSP outpatient will be submitted to very low calorie diet (VLCK) for 6 months, being reassessed clinically and laboratorially monthly.

The study was conducted to assess the impact of coenzyme Q10 and selenium on seminal fluid parameters and antioxidant status in infertile men.

This is a RCT to test the outcome of two protocols used for preparation of the endometrium for frozen blastocyst embryo transfer

Comparing second ejaculate and physiological ICSI (PICSI) as strategies for improvement of abnormal sperm DNA fragmentation in patients undergoing ICSI.

The purpose of the study is to determine whether administration of dietary supplement of astaxanthin with vitamin E improves the quality of sperm, fertilization and embryo development in Assisted Reproduction Techniques (ART) procedures.

Intracytoplasmic Morphologically Selected Sperm (IMSI) is a modification of IntraCytoplasmic Sperm Injection (ICSI) with a choice of the spermatozoon to be injected done at a 6000x magnification instead of 400x commonly used in ICSI. The purpose of this study is to evaluate the efficiency and the indications of IMSI through a multicentric randomised trial.

Background: The number of multiple pregnancies is considered to be the most important adverse effect of in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI). IVF or ICSI with transferring only one embryo, elective single embryo transfer (eSET), will reduce this incidence remarkably. Unfortunately, former research has documented that cycles with SET maintain lower pregnancy rates compared to double embryo transfer (DET). Implementation of eSET will require a carefully chosen and thoroughly defined implementation strategy focussed on the couple undergoing the subfertility treatment. This trial will investigate the (cost)effectiveness of a combined patient centred implementation strategy. Objective: The main aim is to compare the effectiveness and costs of implementation of elective single embryo transfer (eSET) in in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), between usual care and a combined patient-centred strategy. Study design: A randomised controlled trial Study population: Couples with a female age less than 40 years ongoing an IVF/ICSI treatment in 2 of the 13 Dutch IVF centres and their 4 satellite/transport centres. Intervention A combined patient centred implementation strategy for eSET in IVF/ICSI. The strategy consists of counselling through an evidence based decision aid and reimbursement of a 4th cycle if couples have chosen for eSET in the first 2 cycles. Primary study parameters/outcome of the study: the eSET occurrence rate, pregnancy outcomes and cost-effectiveness of the combined strategy. Secondary study parameters/outcome of the study: patient knowledge patient decisional conflict patient satisfaction IVF/ICSI treatment outcome.

This is an exploratory, single center, randomized, parallel, double-blind placebo- and active-controlled trial in adult males ages 18 to 35 years of age who have male infertility of unknown cause. Approximately 50 men will be randomly assigned to one of two treatment groups according to a 1:1 ratio. About half of the men will receive 25mg Androxal and half of the men will receive a placebo (non-active pill) for 16 weeks. This study will last approximately 4 months and involve up to 7 visits. The purpose of this study is to determine the effect the Androxal on sperm production.

Sperms are prepared by sperm washing techniques before used in assisted reproductive technologies. Most commonly used sperm preparation methods are the swim up and the density gradient. Recent studies shows that the DNA integrity status of the spermatozoa is related to the success in assisted reproduction techniques. Sperm preparation methods may theoretically cause damage to sperm DNA. Therefore it is important to select the optimum method of sperm preparation causing least sperm DNA damage. Aim of our study is to investigate and compare the effect two different sperm preparation techniques on DNA fragmentation.
