The term sub fertility means decreased fertility or having a decreased chance of getting pregnant. A sub fertile person has some chances of getting pregnant when compared to an infertile person who might need medical assistance in getting pregnant. A married couple not resorting to any contraceptive measures and sexually active do not have a child even after 12 months may be considered to be sub fertile.
- Ovulation Disorders could be because of an inherent defect of the ovaries (polycystic ovaries), or hormonal imbalance (hormones secreted from pituitary, thyroid or adrenal glands). This can be treated by surgical ablation of cysts in case of polycystic ovaries or medications to generate eggs.
- Blockage of fallopian tubes caused by previous history of operations, infections of the uterus, ovaries etc or appendicitis could cause sub fertility. If one of the two tubes are normal then conception may be possible. In case both the tubes are blocked, then surgery might be required to remove the block or other techniques like in vitro fertilization can be opted for.
- Endometrial disorders: Adhesions or fibroids may hinder the implantation of the embryo within the uterus. This can be diagnosed using ultrasound or hysteroscopy. Removal of the adhesions of fibroids can improve chances of conception.
- Male infertility due to lack of or faulty sperm. If hormone treatment or correction of varicocele do not rectify sperm defects, then techniques such as intrauterine insemination, in vitro fertilization etc can be considered.
Sub fertility can be treated and provide desired results. Simple methods are employed initially. When no cause for sub fertility has been diagnosed techniques like IUI (intrauterine insemination), IVF (in vitro fertilization are also opted. Such methods should be used only when necessary and be performed by an infertility specialist at an approved facility.
