Summary

This trial is testing if it's possible to use a cell called a round spermatid to create a pregnancy, without using sperm. They will also test the safety of this method and what effects it has on the embryo.

Who is the study for?
This trial is for couples facing male infertility due to non-obstructive azoospermia, where the man lacks mature sperm in his semen. Men must have round spermatids present and be over 18 years old. Women partners should be between 18-38 years or have an AMH level above 2 ng/ml.Check my eligibility
What is being tested?
The study tests if injecting round spermatids directly into eggs (ROSI) can lead to pregnancy in cases of severe male infertility. It compares ROSI with using half donor sperm to see which is safer and more effective at creating viable embryos.See study design
What are the potential side effects?
Potential side effects are not specified but may include risks associated with IVF-like procedures such as multiple pregnancies, emotional stress, and complications from egg retrieval or embryo transfer.

Trial Design

2Treatment groups
Experimental Treatment
Group I: ROSI onlyExperimental Treatment1 Intervention
Option 1: injecting extracted round spermatids (less mature form of haploid germ cells than elongated spermatid or spermatozoon) from male partner into the harvested egg of a female partner
Group II: Half ROSI-half Sperm Donor FertilizationExperimental Treatment1 Intervention
Option 2: Harvested eggs from the female partner will be separated in two groups, with one group being fertilized with round spermatids and the other group fertilized with donor sperm

Other Research
Common treatments for male infertility often involve assisted reproductive technologies (ART) that directly manipulate sperm or spermatids to facilitate fertilization. Intracytoplasmic sperm injection (ICSI) involves injecting a single sperm directly into an egg, which is particularly useful for men with low sperm count or poor sperm motility. Round Spermatid Injection (ROSI) is a similar technique where immature spermatids are injected into oocytes to create embryos, offering hope for men with non-obstructive azoospermia who lack mature sperm. These treatments are crucial as they provide viable options for achieving pregnancy in cases where natural conception is not possible due to severe male infertility factors.
