Is there a relationship between necrozoospermia and ectopic pregnancy?

By Laura García de Miguel M.D., M.Sc. (gynecologist on Clínica Tambre).
Last Update: 07/15/2022

Necrozoospermia is the presence of dead spermatozoa in the semen, which may be due to poor seminal quality caused by, for example, severe infections, external factors such as alcohol consumption and other drugs, treatments such as radiotherapy and chemotherapy, hormonal treatments to increase muscularity (anabolic steroids) and also low frequency of ejaculation.

On the contrary, ectopic pregnancy is the implantation of a pregnancy and is related to hydrosalpinx (fluid in the fallopian tubes), IUD use, and in vitro fertilization. The most frequent site of ectopic or extrauterine gestation is the fallopian tube, but it can also be the cervix, the horn of the uterus, the ovary.......

Therefore, there is no association between necrozoospermia and ectopic pregnancy. A large amount of dead sperm in the ejaculate is associated with IVF failure and poor semen quality.

To avoid necrozoospermia, it is recommended to have a healthy diet, with good habits (moderate exercise, no smoking, alcohol or taking drugs) as well as having a semen analysis to negatively confirm it.

To avoid ectopic gestation, during the in vitro fertilization procedure called embryo transfer, it is important to leave the embryo in the middle third of the uterus and not at the bottom of the cavity, where it has a higher probability of implanting in the tube. However, the causes of ectopic gestation are often not known, such as intermittent hydrosalpinx, and therefore if they are not previously identified, they cannot be avoided.
