What is Oligoasthenoteratospermia or OATS?

OATS designates a set of abnormalities found during the spermogram during a male infertility assessment. The OATS groups together a low concentration of sperm (oligo) with therefore too few spermatozoa to naturally fertilize an oocyte, too low mobility of these spermatozoa (astheno) which does not allow them to join the oocyte and too large a proportion abnormal sperm (terato). However, OATS can present varying degrees. It can be severe, with very low mobility and concentration indices while the malformation index is very high. It can be moderate with indices closer to normal. Intermediate forms exist with indices of the same degree or which may be of different degrees: severe for one or two types of indices (eg: mobility and concentration) and moderate for the third.

What happens after diagnosis of the OATS?

Once the OATS is discovered, the doctor will look to determine if there are any causes for these abnormalities. Indeed, OATS can be reduced, at least in part, depending on its origin. He will look first for signs of infections, old or recent. Some infections, such as chlamydia,  can cause a decrease in male fertility. Their treatment can help regain better fertility. Likewise, the treatment of a  varicocele (varicose veins in one or both testicles) or stopping smoking may improve the results of a spermogram. Further research will be carried out to find out if there is a malformation in the testes or seminal tract. In all cases, a second spermogram will be done because it is possible that significant variations appear and allow to hope for other opportunities for natural fertilization.

What to do to have a child in the event of OATS?

If the diagnosis of OATS is confirmed, the possibility of natural fertilization is reduced. However, it does exist, especially if it is a moderate form. However, certain factors, such as the woman's age or the length of time contraception has been stopped must be taken into account and assisted reproduction (ART) may be considered. Depending on the case, it will be an in utero insemination (IUI) where the sperm is introduced directly into the uterus, and in vitro fertilization (IVF) where the sperm is brought into contact with one or more oocytes in the laboratory or an intracytoplasmic sperm injection (ICSI) where sperm is introduced directly into an oocyte in the laboratory. These different techniques will be offered depending on the degree of OATS. The success of IVF or ICSI is of the order of 25 to 30% which leaves hope to those who are concerned by this difficulty.

Asthenospermia is an abnormality of the sperm that is characterized by insufficient mobility while their number remains normal. Also called asthenozoospermia, this sperm fatigue is one of the possible causes of male fertility problems. What are the main causes? How is asthenospermia diagnosed? What treatment is there to promote procreation?

What is asthenospermia due to?

The main causes that can explain unsatisfactory sperm mobility are:

  • a morphological anomaly of the male gametes,
  • an infection,
  • presence of anti-sperm antibodies
  • medication,
  • a  varicocele,
  • a dietary deficiency,
  • a renal failure,
  • liver failure
  • chemotherapy,
  • exposure to radiation,
  • excessive alcohol consumption,
  • a deficiency in calcium,  vitamin D, or trace element ...

How is asthenospermia diagnosed?

A semen analysis, or spermogram, is used to assess the mobility of the sperm. It should be remembered that only mobile gametes can fertilize the egg. Many medical analysis laboratories rely on the classification decreed by the World Health Organization to classify spermatozoa:

  • Level A (or I): progressive rapid sperm advance quickly and in a straight line,
  • Level B (or II): the slow progressive spermatozoa advance slowly or in a curved line,
  • Level C (or III): non-progressive spermatozoa move but do not progress,
  • Level D (or IV): the sperm are immobile.

To be qualified as normal, the spermogram must show a minimum of 40% of motile spermatozoa and 32% of spermatozoa showing progressive mobility.

What solutions to have a child?

The management of asthenospermia varies mainly according to its origin. Thus, an infection will have to be treated according to its nature with appropriate antibiotic drugs while certain testicular abnormalities may, in some cases, be the subject of surgery. While there is no curative treatment for asthenospermia, certain drugs help improve the quality of sperm: vitamins, hormones, alternative medicine (herbal medicine, homeopathy, aromatherapy, etc.). When the treatments do not give satisfactory results, in vitro fertilization with donor sperm or an intracytoplasmic injection of sperm may be considered in the context of Medically Assisted Reproduction ( MAP).) when the couple wants a child.
