LONDON, Jan. 7, 2026 – A couple, previously told their only path to parenthood involved sperm donation, are now expecting a baby thanks to a groundbreaking fertility technique.ItS a story that flips the script on what’s possible, and it’s happening now.
Hope Rekindled: Frist Accomplished Pregnancy After Complete Globozoospermia
A new fertility treatment, ICSI SPARK, has achieved what was once considered impossible: a confirmed pregnancy in a man diagnosed with complete globozoospermia.
- A couple with a history of infertility and 37 failed IVF cycles are expecting a child.
- The male partner was diagnosed with complete globozoospermia, a severe form of infertility where sperm cannot activate an egg.
- ICSI SPARK, a new fertilization technique, achieved successful fertilization, blastocyst development, and an ongoing pregnancy.
- This marks the first documented successful pregnancy worldwide using ICSI SPARK.
For over a decade, the couple navigated a heartbreaking fertility journey, enduring multiple IVF cycles and facing the devastating reality of repeated failure. The male partner received a diagnosis of complete globozoospermia, one of the rarest and moast challenging forms of male-factor infertility. In this condition, sperm lack the ability to penetrate and fertilize an egg, leaving few viable options for biological parenthood.
“Our fertility journey was long and extremely challenging,” the couple shared.”Over more than ten years, we consulted several clinics and specialists, which was emotionally exhausting and deeply affected our wellbeing. With globozoospermia, where outcomes are uncertain, it was very arduous to remain hopeful.”
ICSI SPARK: A New frontier in Fertility Treatment
Persistent to explore every possibility, the embryology team at Avenues applied ICSI SPARK, a next-generation fertilization technique specifically designed for cases where conventional ICSI and artificial oocyte activation have failed.By combining advanced micromanipulation, double artificial oocyte activation, and AI-enhanced laboratory precision, the team achieved a remarkable feat: normal fertilization, blastocyst development, and an ongoing pregnancy in a case of complete globozoospermia.
From a history of zero fertilization to multiple healthy embryos and a confirmed pregnancy, this represents the first documented ongoing pregnancy worldwide achieved using ICSI SPARK.
“For patients who have been told there is no hope of biological parenthood,this opens an entirely new chapter,” said Dr. Halil Ruso, Director of Laboratory Innovation at Avenues. “It shows that even in the most severe male-factor cases, innovation can fundamentally rewrite what is absolutely possible.”
The couple emphasized the difference in their experience this time around. “From the very beginning, this experience felt different,” they said. “For the first time, there was a genuine willingness to explore innovation and research tailored to difficult cases like ours, which restored our hope.”
This breakthrough coincides with growing recognition for Avenues’ research team. They have had 24 abstracts accepted to the 2026 British Fertility Society Conference,including 11 oral presentations and seven shortlisted for national prizes,highlighting their leadership in AI-powered,patient-centered fertility care.
