Royal jelly for unexplained male infertility
This trial tests whether taking royal jelly supplements for 3 months can improve sperm quality and fertility in men with unexplained infertility. It might help if you and your partner have been trying for a baby for over a year without success, and all standard tests are normal.

Varicocele surgery for unexplained infertility in men
This trial tests whether surgery to remove a varicocele (enlarged veins in the scrotum) can help men with unexplained infertility and a normal sperm count become fathers. It's for men who have no other known cause of infertility.
Kafr ash ShaykhAges 18–45 - NCT07404969Recruiting
Integrative medicine for unexplained infertility after treatment
This trial studies whether combining traditional Chinese medicine with standard care can help women with unexplained infertility after previous treatments. It looks at aging markers in your blood to see if they affect your chances of getting pregnant.

Artificial intelligence to improve egg and embryo testing in IVF
This trial uses artificial intelligence to assess the quality of eggs and embryos during IVF. It aims to help doctors select the best embryos for transfer, potentially increasing the chance of a successful pregnancy.
PragueAges 18–49 - NCT06821685RecruitingPhase 1
Natural killer cell therapy for infertility and pregnancy problems
This study tests a treatment using your own immune cells (natural killer cells) to improve pregnancy chances. It's for women with infertility, repeated miscarriages, or other pregnancy complications linked to abnormal natural killer cell function.
Nanjing, JiangsuAges 22–40 - NCT05080569RecruitingPhase 4
Extra support after IUI for couples with unclear infertility
This study tests whether adding support in the period after ovulation (the “luteal phase”) helps people who are starting IUI (intrauterine insemination) because their infertility is unexplained. It’s designed to see if the added care improves chances when mild ovarian stimulation is used.
UtrechtAges 18 years+ - NCT04169451Recruiting
Letrozole with IUI versus natural cycle IUI
This study compares two ways of timing intrauterine insemination (IUI)—using letrozole medicine to help schedule ovulation versus using a natural (untreated) cycle. It may help couples who are trying to conceive with mild or “unexplained” infertility see which approach works better for pregnancy chances.

Study gut and pelvic microbiome in endometriosis surgery
This study looks at differences in the body’s microbes in people with endometriosis (and sometimes infertility) who are having key procedures through a laparoscopy (a small-camera surgery). It may help doctors better understand what’s going on and improve future treatment choices.

- Does it cost anything to join a infertility unexplained trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
