Question

E. Give reasons for the following 1. The sperms are mixed with fluids before ejaculation

​

Answer 1

Explanation:

Pre-ejaculatory fluid is released from the male urethra in amounts of up to 4 ml during sexual arousal, prior to ejaculation. It is said to originate from Cowper’s glands and the Glands of Littre, which open at different sites along the length of the urethra. These glands secrete an alkaline fluid containing numerous enzymes and mucus but no sperm. Despite this lack of sperm, current advice is that any fluid emanating from the penis prior to ejaculation could be contaminated with sperm and therefore should be regarded as potentially fertile and capable of resulting in an unwanted pregnancy. Indeed, the NHS Choices website (2010) states that ‘Millions of sperm are also found in the liquid produced by the penis as soon as it is erect (hard). This means that a man doesn’t have to ejaculate for pregnancy to occur’. Identical statements are found on many other websites. Guidelines therefore recommend condom use from the very first moment of sexual contact (NHS Clinical Knowledge Summaries, 2010) and limit the opportunity for foreplay, hence reducing the popularity of condom use.

Nearly 60% of women aged 15–44 in the USA who have ever had intercourse have used coitus interruptus (withdrawal) as a form of contraception at some time, and among women at risk of unintended pregnancy, 4.6% use withdrawal as their primary method and a further 4.4% use withdrawal plus another method (Mosher & Jones, 2010). In the UK, 5% of women at risk for unintended pregnancy use withdrawal (Lader, 2009). Guidelines for withdrawal (Withdrawal Method. Planned Parenthood, 2004) recommend withdrawing the penis from the vagina when the man feels ejaculation is imminent, but it is not remotely clear how a man would know when he is leaking pre-ejaculatory fluid or indeed spermatozoa.

The source for the claim that pre-ejaculatory fluid contains sperm is entirely unclear. Masters and Johnson stated in Human Sexual Response that there were ‘large numbers of active spermatozoa in the pre-ejaculatory secretion’. However, they were unable to produce data to substantiate that claim (Masters & Johnson, 1966). In fact, to date, no study has found motile sperm in the pre-ejaculate.

This study was designed to establish whether motile spermatozoa are indeed released with pre-ejaculatory fluid and therefore whether the fluid poses a risk for unintended pregnancy.

Answer 2

Well the answer to your question is answered below –

Semen, also called seminal fluid, fluid that is emitted from the male reproductive tract and that contains sperm cells, which are capable of fertilizing the female’s eggs. Semen also contains liquids that combine to form seminal plasma, which helps keep the sperm cells viable.

In the sexually mature human male, sperm cells are produced by the testes (singular, testis); they constitute only about 2 to 5 percent of the total semen volume. As sperm travel through the male reproductive tract, they are bathed in fluids produced and secreted by the various tubules and glands of the reproductive system. After emerging from the testes, sperm are stored in the epididymis, in which secretions of potassium, sodium, and glycerylphosphorylcholine (an enegy source for sperm) are contributed to the sperm cells.

So, the conclusion is that the fluid mixed with sperm is an energy source for sperm and helps in smooth flow of sperm in the reproductive tract of a female...

Hope it's helps
