Summary
Electroejaculation successfully retrieves sperm in most anejaculatory men, offering a viable fertility option. Pregnancy rates were achieved through intrauterine insemination and in vitro fertilization, though sperm motility was low.
Area of Science:
- Reproductive Medicine
- Andrology
- Infertility Treatment
Background:
- Anejaculation, the absence of ejaculation, presents a significant challenge for male fertility.
- Causes include spinal cord injury and retroperitoneal lymph node dissection.
- Assisted reproductive technologies (ART) are crucial for achieving fertility in affected individuals.
Purpose of the Study:
- To evaluate the efficacy of electroejaculation combined with assisted reproductive technologies for treating anejaculatory infertility.
- To assess sperm retrieval success and pregnancy rates in men with anejaculation.
- To analyze the quality of electroejaculates.
Main Methods:
- A cohort of 26 anejaculatory men underwent 84 electroejaculation procedures.
- Sperm retrieval success was defined by specific sperm count and motility thresholds.
- Female partners underwent controlled ovarian hyperstimulation for intrauterine insemination (IUI) and in vitro fertilization (IVF).
Main Results:
- Electroejaculation achieved a 92% success rate for sperm retrieval.
- Intrauterine insemination resulted in a 10% pregnancy rate per cycle, leading to four term infants.
- One pregnancy was achieved via IVF with micromanipulation, and two couples conceived using donor sperm.
Conclusions:
- Electroejaculation provides a promising avenue for fertility in anejaculatory men.
- Significant asthenospermia (low sperm motility) was noted in electroejaculates, requiring further investigation.
- Improving understanding of electroejaculate quality may enhance pregnancy outcomes.

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

01:23Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
