Omega‑3 fat­ty acids per­form important func­tions in the body and are, among other things, com­pon­ents of cell mem­bra­nes. They are also being sci­en­ti­fi­cal­ly stu­di­ed in con­nec­tion with try­ing to con­cei­ve and fer­ti­li­ty. Some stu­dies indi­ca­te pos­si­ble links bet­ween omega‑3 sta­tus and repro­duc­ti­ve fac­tors. Howe­ver, it has not yet been cle­ar­ly pro­ven whe­ther addi­tio­nal omega‑3 inta­ke increa­ses the likeli­hood of pregnan­cy.

Which foods con­tain omega‑3 fat­ty acids?

Omega‑3 fat­ty acids are poly­un­sa­tu­ra­ted fat­ty acids and are, among other things, an important com­po­nent of cell walls. The­re are three dif­fe­rent types of omega‑3 fat­ty acids:

  • ALA (alpha-lin­o­lenic acid)
  • DHA (doco­sa­he­xa­enoic acid)
  • EPA (eico­sapen­tae­noic acid)

EPA and DHA are found main­ly in fat­ty fish and cer­tain algae. The body can pro­du­ce a small amount from ALA.

Omega-3 sources

The fol­lo­wing foods con­tain ALA and/or DHA and EPA:

  • Flax­seed oil & flax­seeds
  • Hemp oil
  • Chia oil & chia seeds
  • Wal­nut oil & wal­nuts
  • fat­ty salt­wa­ter fish (her­ring, sal­mon, macke­rel)
  • Algae

When choo­sing fish, pos­si­ble con­ta­mi­nant expo­sure should also be taken into account.

Omega‑3 fat­ty acids: Effects when try­ing to con­cei­ve

Omega‑3 fat­ty acids are invol­ved in various meta­bo­lic pro­ces­ses and are com­pon­ents of cell mem­bra­nes. Pos­si­ble links with fema­le and male fer­ti­li­ty are also being inves­ti­ga­ted.

Some stu­dies sug­gest that good omega‑3 sta­tus could be asso­cia­ted with cer­tain para­me­ters of sperm qua­li­ty as well as out­co­mes in fer­ti­li­ty tre­at­ments. Howe­ver, the evi­dence is not con­sis­tent. At pre­sent, it is the­r­e­fo­re not pos­si­ble to say with cer­tain­ty that addi­tio­nal omega‑3 inta­ke increa­ses the likeli­hood of a natu­ral pregnan­cy or the suc­cess of IVF or ICSI tre­at­ment.

Endometriosis and trying to conceive

Omega‑3 fat­ty acids: Effects during pregnan­cy?

During pregnan­cy, DHA in par­ti­cu­lar plays an important role in the deve­lo­p­ment of the child’s brain and eyes. The Ger­man Nut­ri­ti­on Socie­ty recom­mends a dai­ly inta­ke of 200 mg DHA for pregnant women. This can be achie­ved, for exam­p­le, by eating one to two por­ti­ons of fish per week, inclu­ding fat­ty fish. Women who do not eat fish can obtain DHA through a sui­ta­ble sup­ple­ment.

Omega-3 supplements

Do omega‑3 sup­ple­ments make sen­se?

Whe­ther an omega‑3 sup­ple­ment is useful depends, among other things, on your indi­vi­du­al diet. EPA and DHA can be obtai­ned, for exam­p­le, from fat­ty fish; for peo­p­le who do not eat fish, algae-based sup­ple­ments are also available.

In the con­text of try­ing to con­cei­ve, indi­vi­du­al stu­dies show pos­si­ble posi­ti­ve asso­cia­ti­ons bet­ween omega‑3 inta­ke and fer­ti­li­ty. Howe­ver, no gene­ral recom­men­da­ti­on can curr­ent­ly be deri­ved to take omega‑3 spe­ci­fi­cal­ly to increase the likeli­hood of pregnan­cy.

The ratio of omega‑3 to omega‑6

Omega‑3 and omega‑6 fat­ty acids are both poly­un­sa­tu­ra­ted fat­ty acids and per­form important func­tions in the body. Becau­se cer­tain fat­ty acids from both groups are part­ly meta­bo­li­zed via the same enzy­me sys­tems, the ratio of omega‑6 to omega‑3 has long been dis­cus­sed.

Howe­ver, the key is not to redu­ce omega‑6 as much as pos­si­ble. More important is an over­all balan­ced diet with an ade­qua­te inta­ke of omega‑3 fat­ty acids. Good sources of EPA and DHA are fat­ty salt­wa­ter fish in par­ti­cu­lar; for peo­p­le who do not eat fish, algae pro­ducts are also an opti­on.

Based on cur­rent rese­arch, no direct link can be deri­ved bet­ween a spe­ci­fic omega‑6 to omega‑3 ratio and a hig­her likeli­hood of pregnan­cy.

Omega‑3 in women’s health

The pos­si­ble influence of omega‑3 fat­ty acids is also being inves­ti­ga­ted in PMOS (form­er­ly PCOS). Stu­dies indi­ca­te effects on indi­vi­du­al meta­bo­lic, inflamm­a­to­ry, and hor­mo­ne para­me­ters. Howe­ver, it is not suf­fi­ci­ent­ly pro­ven whe­ther this results in a rele­vant bene­fit for fer­ti­li­ty or the likeli­hood of pregnan­cy. When try­ing to con­cei­ve with PMOS, indi­vi­dua­li­zed dia­gno­stics and tre­at­ment are the­r­e­fo­re cru­cial.

Posi­ti­ve effects of omega‑3 fat­ty acids

Omega‑3 fat­ty acids also per­form important func­tions in the body regard­less of whe­ther you are try­ing to con­cei­ve. EPA and DHA con­tri­bu­te, among other things, to nor­mal heart func­tion. DHA also con­tri­bu­tes to the main­ten­an­ce of nor­mal brain func­tion and visi­on.

A balan­ced diet with sui­ta­ble omega‑3 sources can help ensu­re an ade­qua­te sup­p­ly. Whe­ther sup­ple­men­ta­ti­on bey­ond this is advi­sa­ble depends, among other things, on your indi­vi­du­al diet and life situa­ti­on.
