The Whelan method is an "intercourse timing" method that advocates the opposite of the Shettles method. The Whelan method suggests intercourse four to six days prior to ovulation to increase the likelihood of fertilization by male sperm.

[34] On the other hand, the Chinese company Nantong Egens Biotechnology recommends using their test twice per day. [35]
It necessitates the test of surge immunity in electrical or electronic equipment. IEC 61000-4-5 defines test set-up, procedures, and classification levels. In particular, it standardizes the required surge voltage and current waveforms for laboratory testing, with the "1.2/50-8/20 μs" impulse being the most frequently used surge waveform.
The LH secretion most noticeable as a LH surge lasting 48 to 72 hours in the middle of the ovarian cycle. [3] Meiosis in the dominant follicle resumes and follicle ruptures shortly after the LH surge. [27] Ovulation can only occur if GnSAF is absent and the mid-cycle LH surge occurs. [3] [27]
