Follicular activation in women previously diagnosed with poor ovarian response: a randomized, controlled trial.

Objective: To investigate whether ovarian fragmentation for follicular activation (OFFA) improves ovarian reserve markers and in vitro fertilization (IVF) outcomes in women with poor ovarian response (POR).

Design: Randomized, controlled trial, with parallel assignment.

Setting: University hospital.

The Use of Vaginal Lubricants and Ultrasound Gels Can have Deleterious Effects on Sperm Function.

Context: Some vaginal lubricants and ultrasound gels are known to be detrimental to sperm function and therefore could negatively affect fertility.

Aims: The aim of the current study was to develop a sperm motility index (SMI) to test the sperm toxicity of ultrasound gels and vaginal lubricants used in reproductive medicine.

Settings And Design: Two ultrasound gels (Aquasonic and Kefus) and five vaginal lubricants (Vaginesil™, Velastisa, K-Y Jelly, Control, and Durex) were studied.
