Direct intraperitoneal insemination and controlled ovarian hyperstimulation in subfertile couples
Direct intraperitoneal insemination with superovulation and washed spermatozoa was performed in 162 couples, yielding pregnancy rates of 21.9% for cervical factor, 20.9% for idiopathic infertility, 4.9% for oligospermia, and 15.5% for ovulatory dysfunction.

The paper evaluated direct intraperitoneal insemination combined with superovulation using washed husband sperm in 162 subfertile couples across 360 cycles, addressing infertility due to oligospermia, cervical subfertility, ovulatory dysfunction, or idiopathic causes. Pregnancy rates per couple were 21.9% for cervical-factor infertility, 20.9% for idiopathic infertility, 4.9% for oligospermia, and 15.5% for ovulatory dysfunction, with an overall pregnancy rate of 33.3% per all couples and 15.0% per all cycles. The main limitation explicitly reflected by the design is that the outcomes are reported by infertility subgroup without any randomized comparison to other assisted reproduction strategies. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
