Necrozoospermia is a condition where dead sperm is found in a fresh semen sample. Read to know more about necrozoospermia treatment offered at Indira IVF!

Necrozoospermia is the medical term that describes presence of dead sperms in fresh semen sample. It is a common cause of male infertility.

Definition:Necrozoospermia is a condition in which there is a low percentage of live sperms and a very high percentage of immotile spermatozoa in semen.

It can be classified into :
Moderate –50 to 80% dead sperms
Severe –>80% dead sperms

Causes of Necrozoospermia

Several pathological mechanisms may be involved which can be due to

1. Testicular cause:Abnormally high Temperature as in Hyperthyroidism, varicocele, hot tub baths

2. Post testicular:Epididymal necrozoospermia, vasectomy reversal, anti-sperm antibodies, seminal plasma abnormalities, adult polycystic kidney disease

3. Toxins:Exposure to toxins such as lead, pesticides, mercury or cadmium

4. Hormonal:Hypogonadotropic hypogonadism

5. Infectionsof male reproductive tract

6.Advanced Paternal age

7.Testicular cancer

8.Spinal cord injuries

9.Prolonged periods of no ejaculation




It can be diagnosed by a semen analysis done in a Laboratory by using an Eosin test or Hypo-osmotic flagellar coiling test.

However it should not be confused with Asthenozoospermia where sperms are non-motile but they are not dead.

Also there can be a possibility of False Positive diagnosis in cases where
1.Sperm is collected in condoms having spermicidal cream
2.Sperm is collected by using lubricants that are spermicidal
3.Sperm is collected in an unsterile container

In cases where in Necrozoospermia is given in a report, it should be rechecked by doing a repeat semen analysis and avoiding possible spermicidal exposure and can also be done by giving 2 semen samples in a day.

Treatment options

1. Etiologicali.e. directed towards the cause by avoiding exposure to high temperatures or toxins and giving antibiotics to treat the infections.

2.Some medications likeAntioxidantsorAnti-inflammatory drugscan be used but there are currently no guidelines to recommend their use.

3. IVF with ICSI:Fertilization rates are lower with Necrozoospermia but in vitro fertilization with ICSI improves the chances of conception.

4. IVF with TESE & ICSI:Also in cases of Necrozoospermia due to post testicular causes, IVF with ICSI using sperm sobtained by TESE is the best treatment possible wherein sperms are obtained directly from the Testis by taking a small incision and removing a small tissue.

5. IVF with DONOR SPERMS:Alternatively in vitro fertilization with Donor sperms should be considered if other treatment fails.
