You are not alone. 1 in 4 infertile couples in Hyderabad have normal reports yet cannot conceive. "Unexplained" does not mean hopeless — it means the cause is hidden. And with the right advanced testing and IVF, we find it and fix it.
Unexplained infertility is the diagnosis given when a couple has been trying to conceive for 12 months (6 months if over 35) without success, and all standard fertility tests return normal results. It is not a rare situation — it is the diagnosis for 1 in 4 infertile couples.
At Mother Hospitals, when standard tests are normal, we go further. Here is what additional testing can reveal:
A semen analysis can be normal while DNA inside sperm is highly damaged. High DFI (above 25%) causes fertilisation failure and early miscarriage. Simple blood/semen test — not done routinely in standard workups.
Tests whether the uterine lining is receptive at the exact day of embryo transfer. If your "window of implantation" is displaced, embryos fail to implant even when perfect. ERA identifies the right transfer day.
A camera inside the uterus can find small polyps, subtle adhesions, or a minor septum that ultrasound misses. Even minor uterine cavity abnormalities can block implantation.
Checks the uterine microbiome — bacteria living in the endometrium. An imbalanced uterine microbiome (lack of Lactobacillus) significantly reduces implantation. ALICE tests for chronic endometritis (silent uterine infection).
Elevated uterine NK cells attack embryos at implantation. This immune factor is invisible on standard tests and may explain repeated IVF failures or recurrent miscarriage with normal embryos.
Only diagnostic laparoscopy can confirm or exclude minimal endometriosis — which is present in 20–40% of women with unexplained infertility and causes no ultrasound abnormality. Treatment during laparoscopy improves conception rates.
Treatment is matched to your age, how long you have been trying, and investigation findings. Here is the standard progression:
For young couples with recent-onset unexplained infertility: CoQ10 for egg quality, folic acid, Vitamin D3, sperm antioxidants, no smoking, limit alcohol, maintain healthy weight. Spontaneous pregnancy rate is 30–40% over 2 years in this group — not zero. But do not wait if you are over 35.
Letrozole or FSH injections to produce 2–3 follicles, combined with intrauterine insemination (sperm placed directly into the uterus). Bypasses some cervical and timing factors. Adds a 10–15% pregnancy chance per cycle for unexplained infertility. Recommended for 3 cycles before advancing to IVF.
IVF simultaneously investigates and treats. In the lab we see: how many eggs are mature, how many fertilise, how embryos develop day by day, whether they reach blastocyst at day 5. Each of these reveals what standard tests cannot. If embryos are good but transfers fail, ERA and EMMA/ALICE testing guide the next step.
If embryos look good but pregnancies are not establishing, PGT-A tests the chromosomes of each embryo before transfer. Only chromosomally normal embryos are selected. This can transform a repeated failure pattern into a successful pregnancy — especially if egg quality issues (invisible to the eye) are the hidden cause.
If repeated good embryo transfers fail, we add the ERA test (to find the exact transfer window), EMMA/ALICE (to treat uterine microbiome), and if NK cells are elevated, immunotherapy with intralipid infusion or steroids. This "personalised transfer" approach significantly improves outcomes in refractory unexplained infertility.
